kyrgyzstan - Opis:
- Paper studies the influence of climate conditions on radial growth of the endemic Schrenk spruce in the Tien−Shan Mountains in Kyrgyzstan. The research was conducted in four forest regions of Kyrgyzstan, where the analysed species occupies the largest area and along altitudinal gradient. Analysed climate factors included mean monthly temperature and precipitation. Additionally, similarity of growth patterns among study sites were compared with GL ratio and pointer years were determined to characterise situations that resulted in growth extremes. The results showed that high Tien−Shan Mountains create different local conditions in individual forest regions for growth of Schrenk spruce. The most important radial growth controlling factor is precipitation. When analyzing the climate−increment reaction it was found that it is affected by the geographical location, altitude and exposure of the analyzed site. Generally, at lower altitudes the main limiting factor was precipitation, while at higher elevations – temperature. This relationship, however, was not observed in all of the investigated regions. It can be affected by a specific climate of the high Tien−Shan causing different reactions of trees in various places. Because of this, the analyses of the Schrenk spruce radial increments should be performed separately within the existing forest regions.
