摘要
以内蒙古自治区西乌珠穆沁旗为研究区域,针对典型草原区水文地质条件和地下水开发利用现状,建立适用于典型草原区的地下水脆弱性评价指标体系,并将典型草原区地下水脆弱性划分为低、较低、中等、较高和高5个等级,对研究区现状地下水脆弱性进行评价,结果表明:该旗典型草原区地质条件复杂,5个地下水固有脆弱性等级均有分布;受人类长期过量开采地下水影响,地下水特殊脆弱性等级为高或较高的区域主要集中在旗政府所在的巴拉嘎尔高勒镇和西部农牧业、工业重镇巴彦花镇;西乌珠穆沁旗地下水脆弱性综合评价等级为高或较高,划分地下水开采控制区和制定地下水开采管理方案是改善研究区地下水脆弱性的有效途径。
Taking west Ujimqin Banner in Inner Mongolia as research area,considering the complex hydro-geological conditions in typical grassland and the current situation of groundwater excessive exploitation,the assessment model of groundwater vulnerability in typical grassland was established. The degree of groundwater intrinsic vulnerability could be divided into five levels of low,lower,middle,higher and high. The present situation of groundwater vulnerability in research area was analyzed. The research results show that the geological condition is so complex that the vulnerability degree of every management zone varies from low to high. With the driving force of excessive artificial groundwater exploitation,the higher or high assessment degree of groundwater specific vulnerability is located in Blag Town,which is the central capital of west Ujimqin Banner and Bayanh Town,which is the base of agriculture and industry. In a word,the comprehensive assessment of the whole Banner is in higher or high degree,so establishing the groundwater exploitation division and making a scientific groundwater management plan are a key way to improve the groundwater vulnerability in west Ujimqin Banner.
