汾河中下游河道水生态修复方案分析

Analysis on Water Ecology Restoration Scheme for Midstream and Downstream River Channel of the Fen River

近十几年来,随着经济的发展,用水量的增加,汾河中下游河道流量减小,加之污水的排放,使汾河中下游的水质及水生态环境恶化,影响了河道水生态系统的健康发展。文中通过对汾河中下游水生态现状的分析,并结合美国Cosumnes河的治理经验,提出生态修复的方案,并进行了综合分析。

In recent ten-odd years, in pace with the economy development and the increase of water use amount, the decrease of water inflow in midstream and downstream river channel of the Fen River, in addition, the draining of wastewater make the water quality and the water ecology environment in these river reaches deterioration. All of these have influenced the healthy development of ecological system of river channel. Through analysing the present situation of these river channels＇ water ecology and in combination with the regulation experience of American＇ s Cosumnes River, the paper presents an ecological restoration scheme and conducts comprehensive analysis.
