摘要
喀斯特地区由于其脆弱的生态环境和不合理的土地利用,造成土壤侵蚀退化严重,形成基岩裸露的石漠化景观,严重影响了当地的农业生产和生态环境,受到人们的极大关注。此文概述了中国西南喀斯特地区土壤水分存在的生态地质环境背景以及土壤水分的测定方法、时空变异性、土壤水分特征及土壤水库容特性等诸多方面的研究进展及存在问题,以期为该地区的生态恢复与重建提供一定的理论依据。
The vulnerable ecological environment and unreasonable land use have caused the soil erosion and rocky desertification in Karst regions, and have seriously affected the local agricultural production and ecologi- cal environment, which have received people＇s great attention. This paper outlined the eco-geological environ- ment background of soil moisture and the progress and the existed problems of the measuring methods, time and space variety, soil water characteristics and storage capacity of soil moisture in Karst areas of Southwest China. The objective of this paper is to offer some theoretical basis for the ecological restoration and reconstruction in the regions.
