| 摘 要： | 目的]认清黄土高原矿区的水环境承载力,科学合理地利用有限的水资源。方法]以黄土高原典型矿区——山西省古交市为例,基于其水文、生态、社会、经济的实际情况,选取了水资源利用率、人均水资源可利用量、人均供水量、生态需水率、生活需水定额、需水量模数、供水量模数、耕地灌溉率和万元工业产值需水量9项评价指标,构建水环境承载力量化模型,对试验区2000,2010,2020和2030年的水环境承载力水平进行评价和预测。结果]各年综合评判结果显示其水环境承载力属于中等偏低的不安全水平,试验区不仅存在资源型缺水,还存在水质型缺水和工程型缺水的状况。结论]水资源的开发利用要注重开源节流、巩固基础工作和重视生态目标以提高黄土高原区域及类似地区的水环境承载力水平。

| Abstract: | Objective] To recognize the water environmental carrying capacity in mining areas in Loess Plateau in order to use the limited water resources scientifically and efficiently.Methods] Taking Gujiao City of Shanxi Province, a typical mining area in Loess Plateau as a case study, based on its hydrological, ecological, social and economic conditions, we selected nine evaluation indexes including utilization rate of water resources, per capita available volume of water resources, per capita water supply quantity, ecological water requirement quantity, water demand quota of lives, modulus of water requirement and supply, irrigation rate of cultivated land and water requirement quantity of industrial output per ten thousand yuan. We then constructed a quantitative model to evaluate and predict the water environmental carrying capacity in 2000, 2010, 2020 and 2030, respectively.Results] According to the final integrated evaluation values in each year, the carrying capacity in the area was in moderate level, and weak and unsafe due to the scarcity of water resources water pollution and incomplete water-providing engineering constructions.Conclusion] Some countermeasures were proposed for the development and utilization of water resources, including opening up the source and regulating the flow, the consolidation of foundation work, the consideration of ecological aims and so on, to improve water environmental carrying capacity in study area and other similar regions of Loess Plateau. |
