| Abstract: | The paper, based on the observed data from typical agro meterological observatory in Huzhu County of eastern Qinghai Province, has analyzed the average soil moisture characters year after year, and in rainy years and dry years; has studied the effective water storage variation within 0~2 cm, 0~50 cm and 0~100 cm soil layers in dry and rainy years; eventually has obtained the transporting law and evolution characters of precipitation in soil layers both vertically and horizentally. |
