摘要
通过对近些年来干旱半干旱地区土壤含水量测定研究情况进行综述,总结了国内外常用的测定土壤含水量的方法及其原理,并对各类测定方法的优缺点进行了评述;介绍了一些新兴的土壤含水量测试技术,并针对其中存在的主要问题提出了展望。
The national and international theories and methods for measuring soil water content in arid and semiarid region for recent years were summarized in this paper. The advantages and disadvantages of all the methods mentioned were discussed. Some new powerful techniques of soil water content measuring were described, and the main problems in this field are proposed as well.
