摘要

土壤水分是影响干旱、半干旱地区植物生长和发育的重要因素。分别采用烘干法、TDR法(时域反射计)和EC－5法这3种方法对毛乌素沙地土壤水分进行了观测。结果表明，3种方法测得的各层土壤含水率之间均无显著差异；3种方法测得结果彼此间相关性显著；EC－5在观测低含水率土壤水分中具有与烘干法和TDR法相当的效果。EC－5土壤水分传感器在组建自动化、网络化土壤监测系统中具有优势。

Abstract

Soil moisture is an important factor for plant growth and development in arid and semiarid areas． We used three methods of drying methods，TDR(time domain reflectometry) and EC-5 sensor to observe soil moisture variations in the Mu Us sandy land． The results show that there was no significant difference in the soil moisture contents measured using the three methods in different layers． The values from the three methods were significantly correlated．EC-5 sensors could be used in observation low water contented soils with a precision level similar to traditional methods like drying and TDR． Furthermore，EC-5 is more suitable in developing an automated soil moisture monitoring network．
