| Abstract: | In order to assess performance of soil moisture sensors of different working principles and models, a field test for 15 soil moisture sensors was carried out at Pishihang evaporation station at Liuan in Anhui province, the station lies in subtropical monsoon climate zone. All sensors were buried for half a year, and assessed by three indexes of stability, flexibility and accuracy, and through a grade method. The results show that the three evaluation indexes are simple, feasible and easy to calculate, and the method can offer objective evaluation of sensor performance. The test is useful to perfection of evaluation system, wide application of soil moisture sensor and construction of drought monitoring system. |
