摘要
运用因子分析与点群分析相结合，研究划分立地类型的主导因子，能实行立地控制，提高工程总体设计的科学性及质量．研究取得的初步成果是：分析导出土层厚度、坡向和土壤速效磷是划分立地类型的主导因子，经定位监测土层厚度与坡向的土壤湿度效应后，确立６个立地类型。
Applying factor and cluster analysis,main factors in division of forest site type were studied. This is able to implement the control of site type and increase scientific quality of the whole project design. The primary results including soil depth,aspect of soil and quick-acting P were the main factors of site type devision. By determining soil depth,aspect and soil humidity,6 site types were divided and basic data were provided for the implement of forest and ecological engeneering in the dry-hot river valley of Yuanmou.
