摘 要:南水北调工程是国家的一项战略性基础工程,受到社会各界的关注。其水源区环境质量状况影响着南水北调工程的供水安全,故而对其水源区环境质量进行科学的评价研究是南水北调工程顺利实施的基础保障。以南水北调中线工程陕西段水源区为研究对象,在实地调查和咨询专家的基础上,科学选取评价指标,运用AHP决策分析方法,构建出该地区环境质量评价体系的层次结构模型;运用信息熵法对其指标权重进行修正,应用模糊综合评判方法,经过定量与定性综合分析验证,最终得出该地区环境质量综合评价结果。该评价结果表明,水源区环境质量一般,有待进一步改善。为了确保南水北调中线工程的顺利实施,促进水源区可持续发展,必须采取有效措施尽快解决影响环境质量的现存问题。South-to-North Water Diversion Project receiving the whole society attention is a strategic foundation subject in our country.Study of the natural environment quality of its water source area is the foundation for South-to-North project smooth implementation,it also has the significant reference value and the practice significance.This article took Shaanxi water source area of the Middle Route of South-to-North Water Transfer as the object,selected evaluating indicator,utilized the AHP decision analysis method,built up the environmental quality evaluation system hierarchical structure model based on on-the-spot investigation and consultation.Its target weight was revised with information entropy method.And then through fuzzy comprehensive assessment method,combination of qualitative and quantitative analysis,the local natural environment quality synthetic evaluation results were obtained.The evaluation result shows that the natural environment quality of water source area is ordinary,it still requires further improvement.In order to ensure the smooth implementation of South-to-North Water Transfer Project,and promote sustainable development of water resources,it should take effective measures to resolve the existing problems affecting the quality of the environment as soon as possible.
