南水北调对海河流域水生态环境影响分析

提出可定量分析研究流域水循环变化对水生态环境影响的关联分析方法 ,并对海河流域现状进行了关联分析和和评价。分析研究表明人类对水资源的过度开发利用已改变了海河流域的天然水循环并导致水生态环境全面退化。进一步对未来无南水北调和有南水北调的情况进行定量模拟计算 ,结果表明在无南水北调的情况下 ,未来海河流域将处于无法兼顾发展经济和保护生态环境的困境 ;在实施南水北调的情况下 ,水资源可支撑海河流域经济发展并影响和改善整个流域的水循环状态 ,从整体上遏制海河流域水生态环境恶化的趋势 ,但入海水量仍无法改善

Analysis of effect of South-to-North Water Transfer Project on aquatic ecosystems of Haihe River Basin

The aquatic ecosystems are closely correlated with the water cycle in a river basin. The large-scale water resources and utilization in the Haihe River basin have altered the natural water cycle, thus resulting in the overall degradation of the aquatic ecosystems in the river basin. The South-to-North Water Transfer Project may transfer water from the Yangtze River to the Haihe River basin, thus increasing flux of the water cycle and influencing the ecosystems in the river basin. This paper develops a metho...
