摘要
为量化人类活动对地下水水位的影响,本文以新疆开都-孔雀河流域为研究区,选取人口数量、机井数量等作为评价指标,采用改进的TOPSIS法构建评价模型。评价结果表明:机井数量、地下水灌溉面积、年地下水开采量与区域国民生产总值是影响地下水位的主要因素;焉耆县、博湖县与和静县人类活动对地下水水位的影响微弱,和硕县为中等,尉犁县为高,库尔勒市为严重,当地政府应当采取有效措施加以遏制。研究结果对于指导当地地下水资源的合理开发利用具有一定的参考作用。
In order to quantify the impact of human activities on groundwater level,this paper takes Kaidu to Kongque River basin in Xinjiang as the research area,selects the population number and the number of wells as evaluation indexes,and uses the improved TOPSIS method to construct an evaluation model.The results show that the number of wells,the area of groundwater irrigation,the annual groundwater exploitation and the regional gross national product are the main factors that affect the groundwater level.The influence of human activities on groundwater level is weak in Yanqi County,Bohu County and Hejing County,medium in Heshuo County and high in Yuli County.Korla is serious,and the local government should take effective measures to contain it.The research results have certain reference value for guiding the rational development and utilization of local groundwater resources.
