摘要: 简要回顾了有关荒漠植被对土壤水文过程影响的试验研究,介绍了荒漠地区土壤水文过程研究的主要方法以及基本的土壤水分平衡方程,并对特定区域土壤水分动态与植被结构之间的关系进行分析,以期对今后从事该领域的研究与管理者有所启示。由于荒漠地区土壤水文特性具有极高的变异性,因此,阐明荒漠植被区土壤水分动态,确定这一特殊生态系统内植被格局与土壤水文过程的关系,可在理论上回答雨养型人工植被建设与荒漠地区生态恢复工程中,土壤水文过程影响植被结构与格局的基础性科学问题。

关键词: 土壤水分, 荒漠生态系统, 雨养植被

Abstract: The main impacts of desert vegetation on soil hydrological processes are briefly reviewed in order to highlight needs and perspectives for research and management goals. This review is based upon the distinct influences of desert vegegtation on soil hydrological processes. Precipitation, as the sole source of water replenishment in the semi-arid area, plays a pertinent role in sustaining the desert ecosystem. The objective is to describe and model the transportation of soil moisture between the elements of this integrated artificial system and to understand how these transporting paths influence and are influenced mainly by vegetation patterns and stability. The aim of the activities is to give a theoretical answer for the basic scientific problems of how the soil water dynamics influencing the vegetation construction and pattern in the establishment of rainfed artificial vegetation and the ecological recovery of desert area in western China.

Key words: soil water, desert ecosystem, rainfed vegetation
