黄土高原土壤水库及其影响因子研究评述

土壤是疏松多孔体,具有存蓄和调节土壤水分的功能。就目前黄土高原土壤水库及其影响因子进行了评述,重点阐述了土壤水库功能及其与三个主要影响因子(气象因子、植被因子、土壤因子)的关系,并对今后的研究做了展望。土壤水库下边界的界定、不同因子对土壤水库的影响以及土壤水库模型的构建等都有待进一步的研究。

Soil is the loose and porous body,which has the function of holding and adjusting water.This paper summarized the main problems about soil water reservoir in the Loess Plateau.The reviews are focused on four factors(climate factor,vegetation factor,soil factor and terrain factor).At last,the forecast has been made to the further study in the basis of summing up the studying in the past.The definition of soil water reservoir s bottom boundary and the construction of its related models need further study.
