【摘要】 选取南水北调中线一期工程受水区为研究对象,以受水区涉及的112座县级市(区、县城)为单元,进行生态水文分区。根据受水区的生态水文特征,建立生态水文分区的指标体系值数据库。经过SPSS聚类分析,共分为5个生态水文区。系统分析了各生态水文区的生态水文特征,尤其是对表征地下水超采严重程度的指标——地下水位的动态变化进行了重点分析。分区结果可为深入进行南水北调中线工程沿线生态影响评估及水资源可持续管理提供科学依据。更多还原

【Abstract】 The water receiving areas of the Phase I Project of the Mid-route of South-to-North Water Transfer Project are selected to be the research objects,and then 112 counties and districts in those areas are taken as the units for the analyses concerned;for which the eco-hydrological regionalization is made.Based on the eco-hydrological features within the areas,the indicator system database for the eco-hydrological regionalization is established.Through SPSS-cluster analysis,5 eco-hydrological regions are divided.Furthermore,the eco-hydrological characteristics of each region are systematically analyzed,and especially the indicator of the severity of the groundwater over-mining of the characterized groundwater—the dynamic changing of the groundwater is emphatically analyzed as well.The results of the regionalization can provide a scientific basis for the further ecological impact assessment and sustainable management of the water resources along the Mid-route of the project.更多还原
