通过逐步回归分析表明 ,影响粗枝云杉人工幼林生产力的主导气象因子是年平均温度 ,林分生产力与年平均温度呈正相关。按林分生产力的差异显著性 ,将四川省粗枝云杉人工林划分为三个产区 ,其生产力大小排序为 类 > 类 > 类 ,粗枝云杉中心分布区并不一定是中心产区。 The results of stepwise regression analysis showed that the dominant meteorological factor affecting the productivity of young spruce plantations was the annual average temperature, and the stand productivity was positively correlated with the annual average temperature. According to the difference in stand productivity, the plantation of the rough spruce plantation in Sichuan Province is divided into three producing areas, and the order of their productivity is Class> Category>. The distribution area of ​​the center of the spruce is not necessarily the central producing area .
