南水北调中线水源区水文特征分析及其 水资源适应性利用的思考

南水北调中线调水工程是为了解决华北地区缺水问题而采取的特大型调水工程,水源区地理特征是调水水量和水质的重要基础。然而,从目前的研究现状看,对水源区边界、面积、河流长度等主要特征参数和水资源特征系统梳理不足,水资源利用仍存在一些问题。基于此,从地理学的角度,借助地理信息技术和统计学方法,结合实地调研,对南水北调中线水源区主要特征参数进行系统梳理;分析和总结水资源特征、水资源开发利用演变过程以及存在的问题;基于水资源适应性利用理论,结合南水北调中线水源区实际,提出其水资源适应性利用的研究思路和战略措施建议。研究成果对保障南水北调中线可持续调水、支撑水源区水资源开发利用和协同管理提供技术支撑。
