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～ 2 0 cm、0～ 5 0 cm、0～ 10 0 cm土层有效水分储量年际变化 。
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.
