黄土高原地区造林土壤水分生态分区研究

Soil Water Ecological Regionalization of Afforestation in Loess Plateau

通过对黄土高原地区土壤水分背景、地带性和非地带性因素的综合分析，采用逐步判别分析法，定量地分析了多种因素的作用，同时结合经验的定性分区方法，将整个黄土高原地区划分为六个土壤水分生态区。此外，就人工林对土壤水分生态环境的影响进行了讨论。

Based on the synthetic analysis of soil water background,zonal and azonal factors in LoessPlateau,the stepwise discriminate analysis method was used for conducting soil water ecological re-gionalization of afforestation,meanwhile,it was combined with the traditional qualitative method of di-vision,the Loess Plateau has been divided into six soil water ecological areas of afforestation. More-over,the influence of man- made forest on soil water ecological environment was discussed.
