摘要
土壤水分对作物生长和微生物活动具有重要作用,对农业、工程、生态等领域均有十分广泛的影响。土壤含水率是土壤理化特性的重要参数之一,也是制定合理灌溉制度、优化水资源管理、保障土体工程施工安全的重要指标之一。本文介绍了目前国内外应用较广泛的几种土壤水分测量方法及其测量原理,对其优缺点进行了分析,并提出了土壤水分测定方法中存在的主要问题及其发展趋势。
Soil moisture plays an important role in crop growth and microbial activities,and has a very wide range of effects on fields of agriculture,engineering,ecology,etc.Soil moisture content is one of the important parameters of soil physical and chemical characteristics,and it is also one of the important indicators for formulating a reasonable irrigation system,optimizing water resources management,and ensuring the safety of soil engineering construction.This paper introduced several widely used soil moisture measurement methods and their measurement principles at home and abroad,analyzed their advantages and disadvantages,and put forward main problems and development trends in soil moisture measurement methods.
