Multiple regression analysis of the climatic and edaphic predictors of NDVI and BS retained following stepwise model simplification based on AIC.

The standardized coefficients for each variable are shown with their P for inclusion in the model. The r2 and P for the overall models and intercepts are also included (bold).Multiple regression analysis of the climatic and edaphic predictors of NDVI and BS retained following stepwise model simplification based on AIC.各变量的标准化系数及其纳入模型的P值均已展示。整体模型与截距项的决定系数（r²）及对应P值也一并给出（已加粗标注）。针对归一化植被指数（Normalized Difference Vegetation Index, NDVI）与BS的气候及土壤环境预测因子所开展的多元回归分析，系基于赤池信息准则（Akaike Information Criterion, AIC）完成逐步模型简化后所留存的分析结果。
