initial condition models - Opis:
- Tested are three approaches to development of site dependent height age model based on published Scots pine tabular data. The approaches included fitting four−parameter modified Gompertz function individually to all site productivity classes; fitting a one−parameter anamorphic dynamic site index equation to all the data; and fitting a three−parameter polymorphic dynamic site index equation with variable asymptotes to all data. The common fit to all data was based on a base−age invariant approach, in which the site−specific parameters different for each of the site productivity classes are estimated simultaneously with the global model parameters that are common to all site productivities. The best model proved to be based on the polymorphic dynamic equation with variable asymptotes by Cieszewski [2001, Three methods of deriving advanced dynamic site equations demonstrated on Inland Douglas−fir site curves. Can. J. For. Res. 31(1): 165−173], which fitted the data best and provided one common model for all the site classes. The produced model was concluded to be superior to the other models and to the original tables. The presented approach is recommended for modeling of other stand growth attributes.
