通过对侧柏林分结构特性、林地立地条件、林分密度的研究分析,证实了植被盖度、林地立地条件、林分密度对土壤侵蚀有重要影响。采用挑选主导因子分析的方法,筛选出郁闭度、草本盖度、灌木盖度三个主导因子,并将其林分划分出高结构型、高中结构型、中结构型、中低结构型、低结构型5个水土保持结构类型,为河南省太行山区营造水土保持林提供了依据。
Through the analysis of the structure characteristics, the site conditions and the stand density of the forest, it was confirmed that the vegetation cover, the site condition of the forest land and the stand density had an important influence on the soil erosion. The main factors of canopy density, herbaceous coverage and shrub coverage were selected by the method of selecting leading factor analysis, and the stand was divided into three types: high structure type, high structure type, middle structure type, middle low structure type, Five low-structure types of soil and water conservation structures provide the basis for the construction of soil and water conservation forests in Taihang Mountainous area in Henan Province.
