Abstract: TDR has been applied to the field experiments in many research projects of the Hei River Basin extensively as an effective technology to measure the soil moisture. This paper is intended to briefly introduce the development, principles and types of TDR, then mainly to analyze the characteristics, advantages and influence factors of the TRIME-TDR which is the patent product of IMKO Company in Germany. The TRIME-TDR measurement system has been installed in the different vegetation landscape zones of the Hei River Basin. As compared with the other soil moisture measurement instruments such as the capacitive moisture measurement instrument, neutron moisture instrument and traditional TDR, the TRIME-TDR has the advantage of reducing the influence of the electricity conductivity, having the large measurement range of soil moisture with various sensors, suitable for the measurement of the inhomogeneous soil and easy to handling in the field investigations. From our experience of the utilization of TRIME-TDR in the field measurement, some suggestions and recommendations are presented for the better and effectively utilization, installation and maintenance of TRIME-TDR measuring system.

Key words: TRIME-TDR technology, measurement of soil moisture, Hei River Basin
