| 摘 要： | 通过对粗枝云杉天然分布区的地理、气象因子统计分析 ,证明年降雨量以及降雨月份分布不是影响粗枝云杉生长的主要因子。不同的种源林分间总年平均径生长量、前 30年年平均径生长量、木材基本密度、纤维长度、纤维宽度、长 /宽比值差异显著。经过综合分析 ,在四川省将粗枝云杉纸浆材种源林分划分为 4个种源区

| Abstract: | Statistical analysis on geographical and meteorological factors innatural distribution districts of Picea asperata have shown that annualrainfall and its monthly distribution are unimportant among the factorsaffecting growth of the tree species. Of the provenance standsinvolved, significant differences demonstrate in annual diameter increment averaged over both the chronological age and its first 30years, basic density of wood, as well as fibre length and width and theirratio. On the basis of a comprehensive analysis four different provenanceareas have been divided for woodpulp stands of Picea asperata. |
