Opis:
The urbanisation and suburbanisation processes are considered to have a detrimental impact on the environment. Increasing the share of the impervious surfaces is one of their main negative effects, particularly in and near the cities, affecting the water relations of basins. It also results in new catchment boundaries formation and, in many cases, changes in the physiographic parameters affecting the accuracy of hydrological and hydraulic calculations of small suburban catchments. This study is an attempt to delimit the catchment boundaries located in the suburban area of Poznań city, Poland, in three variants: according to the Raster Hydrographical Map of Poland and Raster Topographical Map of Poland, digital elevation model, and rainwater sewage system. The analyses were conducted with ArcGIS software, and the results were additionally verified with geodesic measurements on site. This work focuses mainly on the impact of anthropogenic pressure on the catchment shape and the course of its boundaries. The analyses were conducted on the Rów WB stream catchment located in the Skórzewo village, Dopiewo municipality, which stands out within the Poznań Metropolitan Area as the area where the suburbanisation process is the most intensified. This study proved that the agrotechnical and drainage works performed in undeveloped, agricultural areas affected catchment shape and size as much as suburbanisation itself. According to the authors, the suburban catchment boundaries should be regularly updated due to the intensity of the new investments development and additionally verified on site.

Opis:
Leaf area is linearly correlated with sapwood area in trees. The linearity of this relationship can be affected by some biotic and abiotic factors. Mistletoes are hemi parasitic plants that take up water and mineral nutrients from their hosts and affect host physiological responses. There is no conclusive evidence to show the effect of pine mistletoe (Viscum album ssp. austriacum) on leaf area and sapwood area relationship in Scots pine trees (Pinus sylvestris L.) at tree level. The aim of this study is to determine and quantify the effect of pine mistletoe on the structural variation of leaf area and sapwood area relationship at tree level in Scots pine. A total of 18 mistletoe infected and 12 uninfected Scots pine trees were destructively sampled. All needles and mistletoes were completely removed from sampled trees to determine needle and mistletoe characteristics, biomass and leaf area. Sapwood areas at breast height (BH) and at crown base height (CBH) were determined from wood discs taken from BH (1.3m) and CBH. Sapwood area was delineated by benzidine staining method. Pearson correlation, t-test and regression analyses were conducted to determine the relationship between sapwood area and needle-mistletoe leaf area relationships. The results indicated that both the relationships between sapwood area and leaf area in uninfected, and sapwood area and total leaf area (needle plus mistletoe leaf only) in infected trees were linear. However, the slope of regression equation for mistletoe infected trees was considerably lower when compared to the uninfected trees. As for the variation of the sapwood area along the stem below live crown, there was a slight difference between sapwood area at BH and CBH. The study showed also that mistletoe infection led to a significant reduction in needle size (length, width, area and weight) in Scots pine trees. Significant relationships were found between the sapwood area and leaf area in this study. The results of this study may help fill the gap in the knowledge concerning the impacts of pine mistletoe on the dynamics of Scots pine trees.

Opis:
Zgodnie z kierunkiem zintegrowanego podejścia terytorialnego (integrated territorial approach) miejskie obszary funkcjonalne ośrodków wojewódzkich wymagają prowadzenia spójniej, całościowej i skoordynowanej polityki rozwoju. Obecnie w Polsce brakuje uregulowań prawno-organizacyjnych rozwiązujących kwestię zarządzania wielopoziomowego. W takiej sytuacji rolę koordynacyjną przypisać można planowaniu przestrzennemu w skali regionalnej i subregionalnej. Jednym z jego elementów jest ocena realnej chłonności terenów przeznaczonych pod zabudowę. W artykule przedstawiono metodę analiz będących podstawą do szacowania chłonności terenów w miejskim obszarze funkcjonalnym Wrocławia. Analizami objęto 25 gmin wiejskich i miejsko – wiejskich oraz jako obszary odniesienia gminy miejskie Oława, Oleśnica i rdzeń obszaru, jakim jest Wrocław. Przyjęto założenie, że w analizach wykorzystane zostaną ogólnodostępne dane statystyczne i na tej podstawie zaproponowano zestaw wskaźników, w podziale na przestrzenne, demograficzne i środowiskowe. Zakres analiz obejmuje lata 1995, 2005 i 2015. Celem pracy jest charakterystyka obszaru funkcjonalnego Wrocławia pod kątem jego potencjalnej chłonności oraz porównanie uzyskanych wyników w czasie i przestrzeni. Zaproponowana metoda bilansowania może być przydatna do wyznaczania racjonalnych kierunków planowania i zagospodarowania przestrzennego na szczeblu lokalnym i subregionalnym.
In accordance with the integrated territorial approach, the urban functional areas of regionalcentres require a coherent, comprehensive and coordinated development policy. Currently, there are neither legal nor organizational regulations in Poland solving the problem of multi-level management. In such situation the coordinating role can be attributed to spatial planning in both regional and sub-regional scale. One of its elements is the real capacity assessmentof the land planned for development.The article presents the method of analyses being the basis for estimating area capacity in the urban functional area of Wroclaw.The conducted analyses covered 25 rural and urban-rural municipalities, and as the reference areas the municipalities of Oława, Oleśnica and the core area i.e.Wrocław. It was adoptedthat the generally available statistical data will be used in the analyses and on this basis a set of indicators, divided into spatial, demographic and environmental criteria, was proposed. The scope of analyses covers the years 1995, 2005 and 2015. The purpose of the study is to characterize the functional area of Wroclaw in terms of its potential capacity and to compare the obtained results in time and space. The suggested balancing method can be useful for determining rational planning and spatial management directions at a local and sub-regional level.

Knowledge of surface runoff characteristics allows creating better conditions for landscape management, whether rural or urban. We focused on a determination of a volume of surface water runoff and it velocity in this paper. A direct measurement was done on an experimental area with three different slopes in a laboratory. Results of direct measurements were compared with results from a model SMODERP and NRCS method used in GIS environment. The velocity of surface runoff was also calculated by a mathematical equation used in literature. The results of surface runoff volume from GIS were equal in all cases, but not the velocity. The results of SMODERP simulation and direct measurements are similar. The calculated velocity was the highest in case of first slope, and the lowest in other cases. Differences of the velocity varied in a range 1.10 - 11.06 %. The volume of surface runoff varied more, mainly the results of NRCS Curve Number method in GIS (up to 41 %). The results show that the higher slope, the higher runoff velocity and volume is.

Opis:
Domain estimates are typically obtained using calibration estimators that are direct or modified direct. They are direct if they strictly use data within the domain of interest. They are modified direct if they use both data within and outside the domain of interest. An alternative way of producing these estimates is through small area procedures. In this article, we compare the performance of these two approaches via a simulation. The population is generated using a hierarchical model that includes both area effects and unit level random errors. The population is made up of mutually exclusive domains of different sizes, ranging from a small number of units to a large number of units. We select many independent simple random samples of fixed size from the population and compute various estimates for each sample using the available auxiliary information. The estimates computed for the simulation included the Horvitz-Thompson estimator, the synthetic estimator (indirect estimate), calibration estimators, and unit level based estimators (small area estimate). The performance of these estimators is summarized based on their design- based properties

Opis:
The article presents the essence, goals and instruments of soft (informal, non-statutory) spatial planning, developed in the countries of Western Europe and relatively new in Poland. It targets areas with fuzzy borders (soft spaces) and areas between administration tiers. The article presents conceptual issues and non-formal planning tools used in Western Europe. The planning approaches which are generally described as “soft” are characterised by non-formalised and non-binding procedures, and by their focus on achieving a consensus. In the first part of the article presents the conceptual issues and further informal planning instruments used in Western European countries at diferent spatial scales The following section presents deficits of spatial planning of metropolitan areas and against this background - the legitimacy of creating informal plans in Poland, using Metropolia Poznań as an example

This paper presents one of the approaches to solve the collision problem in restricted area for two moving objects using artificial intelligence (SACO algorithm). Although AI should be used only when the classic methods fail, a simple comparison between them is very interesting. As we know the main task of navigation is to conduct safely an object from the point of departure to destination. This problem does not seem easy, especially if we consider the movement in restricted areas such narrow passages, ports etc.

Opis:
Individual tree growth models are important decision-making tools in forestry. This study evaluated the predictive ability for basal area, of a Java program derived from the algorithm of gamma distribution function. The input value was diameter at breast height. In generating and testing the program, a stratified random sampling technique was used to select four different age classes of teak plantation, namely: 11, 13, 22 and 59 years-old, respectively. Complete enumeration of trees (n = 433) was done for all the plots selected. Diameter at breast height (DBH) was measured with the aid of diameter girth tape, which was also used for basal area computation. Data obtained were processed into tree and stand levels. Parameters α and β for Gamma Distribution function (GDF) were estimated from growth data. The java program was then written based on the algorithm of Gamma distribution function for α, β and n parameters. Values of diameter at breast height fitted into the Java program shows that it was able to predict the basal area. Therefore, the predictive ability of the developed Java Program for basal area of individual and full stand teak trees demonstrates that it can be used for prediction of yield in forest stands.

The investigated area lies in the geographical centre of Lublin Province. More specifically, it is located in the northern part of the Central Coal Region, between the Puchaczów-Urszulin route and the route leading through the village of Szczecin, which the investigated inundated area is named after, and between the town of Dratów and the ”Bogdanka” Hard Coal Mine. The Lublin Upland, with the Lublin Coal Basin located in its centre, has one of the most valuable natural environments in Poland. There are many reserves, Poleski National Park and Natura 2000 area. The process of the intensive hard coal exploitation makes subsidence of surface as its result. The process of basin subsidence is irreversible. This paper deals with the problem of forming an anthropogenic water reservoir and its development in compliance with the policy of sustainable development and biodiversity maintenance in the face of heavy hard coal exploitation. It is suggested to use fluorides ground water to organize a health resort based on water reservoir and the described natural environment.

Opis:
Cities and urban agglomerations shape the process of economic development in a significant way, both in national and regional scale,. The desire to improve the level and dynamics of economic development of an agglomeration and surrounding areas requires a coordination of actions undertaken by local governments of units forming an agglomeration. This, in turn, raises an important issue of determining the spatial extent of their impact. The aim of the study is to delimitate the boundaries of functional area of Olsztyn agglomeration. Agglomeration area is a highly integrated functional area where various functions are realized like, for example, manufacturing, consumption, administrative or commercial. These functions are realized in different parts of an agglomeration area, so in that respect it is not uniform, but there is always a high degree of integration and an intensity of relationships. Most often used, but not the only one, criterion for the delimitation of functional urban region is the spatial extent of daily commuting. The factors used to delimitate the functional area of Olsztyn agglomeration relate to morphological criteria (that is associated with the degree, intensity of use of space), the functional criterion (reflecting the degree of relationship between the center city and surrounding area) and a criterion of the dynamics of socio-economic processes taking place in the urban area (they refer primarily to the dynamics of migration processes and to the economic development of the surveyed units). One of the characteristic features of urban agglomerations is, in fact, greater intensity and variability of changes taking place in its functioning. The analyzes lead to the conclusion that the functional area of Olsztyn agglomeration consists of 12 municipalities (except the city of Olsztyn) – nine of them belong to the Olsztyn poviat (Barczewo, Dobre Miasto, Dywity, Gietrzwałd, Jeziorany, Jonkowo, Purda, Stawiguda, Świątki), two to the Szczytno poviat (Dźwierzuty, Pasym) and one to the Ostróda poviat (Lukta). The functional area of Olsztyn agglomeration at the end of 2010 consisted of 268 684 people, representing 18.8% of the population of Warmińsko-Mazurskie Voivodship. The size of the area is, in turn, 2 682 km2, which makes 11.1% of the voivodship. The agglomeration is home to the largest and most important in Warmia and Mazury region employers, government agencies and local governments, colleges and universities. In Olsztyn there are also located important for the whole region cultural and economic institutions as well as health care facilities. The production structure is dominated by the food industry, machinery, furniture and tire production. Tourism is also an important industry, because of its location and the landscape.

The paper presents the evaluation of the possibility to apply the Normalized Difference Vegetation Index (NDVI) to determine the burned area using the machine vision method. Digital analysis to determine the NDVI has been based on images obtained by transducers in visible light and near infrared (NIR). Under appropriate conditions, the described method offers an alternative to the existing methods of observation and manual measurement. As great progress has been made in the field of unmanned aerial vehicle data acquisition, the method described constitutes a possible solution especially in cases when evaluation of loss assessment caused by external fires is supposed to be prepared.
