摘要: 根据青海省东部农业区具有代表性的互助农业气象观测站观测资料,分析了多雨年、干旱年和历年平均土壤湿度特征,研究了旱年和多雨年土壤0~20 cm、0~50 cm、0~100 cm土层有效水分储量年际变化,得出了大气降水在土壤中各层次垂直和水平输送规律和演变特征。

关键词: 水分, 分布, 土壤, 青海东部

Abstract: The paper,based on the observed data from typical agro-meterological observatory in Huzhu County of eastern Qinghai Province,has analyzed the ave rage 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.

Key words: soil moisture, distribution, eastern Qinghai Province
