Abstract: In recent two decades or so, time-domain reflectometer (TDR) have greatly developed in soil parameter measurement. Especially in soil water content determination, it has great practical application and developing potentiality. This paper briefly introduces recent progresses of TDR. In the mean time, its determining items and precision are also presented. Now, it is expected to use TDR in China.

Key words: time-domain reflectometer (TDR), parameters determination, review, cold regions
