摘要:

黄土高原地区深层土壤干燥化(土壤干层)是人工林草植被过度耗水导致土壤水分负平衡的结果。概述土壤干层的研究进展,包括土壤干层的特征、类型、量化指标、成因、分布、危害及其缓减对策,指出当前研究中存在的问题,对今后研究提出建议。

Abstract:

The desiccation of deep soil layer on the Loess Plateau results from the gradual depletion of storing water during the process of vegetation rehabilitation. The desiccation of deep soil layer related to vegetation rehabilitation on the Loess Plateau was reviewed, including its characteristics, types, quantitative indexes, contributing factors, distributions, harmfulness and countermeasures. Moreover, some problems and suggestions in the relevant researches were presented.

Key words: the Loess Plateau, desiccation of deep soil layer, vegetation rehabilitation, soil water
