中文摘要：

探讨了TDR测定土壤含水量的原理,并对黑河上游阿柔试验样地取土样进行了土壤体积含水量测定的室内标定试验,得出相关性较好的TDR测定土壤体积含水量的关系式.结果表明:通过室内土样回填建立的TDR测定的体积含水量与土壤实际含水量相关性很好,可以利用TDR精确的测定土壤含水量,为黑河遥感项目提供精确的地面土壤水分数据,为遥感反演和验证提供基础数据.所得到的标定结果对于具有相同土质的黑河中游土壤具有参考价值.

英文摘要：

It is necessary to calibrate Time Domain Reflectometry(TDR) for a measurement that a small error is required.By calibrating,the scope of application and accuracy of TDR can be determined.In this paper,a calibration process/method of the measurement of soil water content by TDR is discussed and analyzed.In addition,the fundamental principles and theory of the measurement of soil water content by TDR has also been generally reviewed and discussed.The designed calibration experiment processes are described in ...
