地下水埋藏深度

各种优化目标的最佳地下水埋藏深度探讨

Optimum Ground Water Depths for Different Optimized Objectives

全流域地表径流产生与降雨关系的试验研究，有助于分析当地气象因素以及降雨时段之初的包气带含水率和地下水埋藏深度，为污染负荷总量核算提供参考和借鉴。

The study on rainfall-runoff correlation will be good to analyze water content in air inclusion zone and depth of subsurface runoff , which provides references for total pollution loading calculation of Dianchi lake .

水分是植物赖以生存的基本因子，黄土高原大部分地区位于干旱半干旱气候区，降水量较少，加之地下水埋藏深度大，土壤水分成为植物生长发育所需水分的主要来源。

Water is the fundamental factor in plant growing . Because most area of loess plateau lies in arid and semiarid region where precipitation amount is small and groundwater table is deep , soil-water is the main water course for the vegetation .

地下水的埋藏深度是决定土地盐渍化的重要因素，在内陆干旱区则更加明显。

Ground water level dominates the formation of salinization , especially in the inland arid areas .
