ground water depth 地下水深度
prediction of ground water depth 地下水埋深预测
critical depth of ground water 地下水临界深度
Ever frozen ground prevents water from infiltrating to deep layer, which increases the depth of runoff and intensity of transpiration.
同时多年冻土抑制水分向深层土壤的下渗，增加了径流深度和蒸腾发强度。
There existed close relationship between ground water depth and precipitation (the correlation coefficient 0. 9036).
降水与潜水埋深有密切关系，相关系数达0.9036；
The key factors causing soil dried layers are great thickness and depth of membrane water zone under ground as well as small thickness of gravity water zone.
由降水少量决定的、埋藏深度小而厚度大的薄膜水带的存在是引起土壤干层发育的直接作用的因素。
