| Abstract: | Through the analysis on the change regulation of soil moisture in arid land of Qinghai Province, it was found that the precipitation affets obviously on the naked soil moisture. The level and vertical soil moistures are more than the grassland and crops land. The soil moisture of natural grassland shallow layer (0-30cm) affected greatly by the weather condition and herbage growth. During herbage returning green, the shallow layer moisture is most less, 40-60cm soil layer is rich in moisture,it meets the moisture lack in shallow layer. During herbage growth, the 20cm soil layer moisture is in lowest period, and be the highest in 40-60cm layer,it is much stable in 70-100cm layer. |
