基于FVS的华北落叶松人工林树高生长量模型研究
Individual Height Growth Model of Larix principis-rupprechtii Based on FVS
摘要
Abstract
Based on lots of data from temporary sampling plots of artifitial stands and the data of analytic woods of Larix principis-rupprechtii, multi-linear regression function was used to simulate individual height growth of L. Principis-rupprechtii. Tree size and site conditions were selected as independent variables. The coefficient R2 of the model was 0. 516. Through stepwise multiple regression analysis,the impact of the variables on the height growth ranked as tree size, and site conditions. The model of tree growth height were tested by applying the test database,the predicitive value was 2. 77 m,slightly higher than the measured value 2. 74 m. However,t-test showed that the difference was not significant.关键词
