| 摘 要： | 本文在判明低效林分改造试验林的现实林分结构具有趋同性的情况下，采用主成份分析和谱系聚类法进行聚类，依据聚类的结果作了水土保持效应的分析。通过逐步回归分析，揭示了林分结构要素在控制水土流失方面的作用。

| Abstract: | On the basis of the fact that the fact that the structures of actual reforested stands developed in the same trend and by the clustering analysis,the author studied the effects of the reforested stands and confirmed that the crucial importance of the stands structures is to control the erosis of water and soil. |
