Analysis On Ecological Problems In Benxi Segment Of Taizi River And Scheme Design Of Remediation

As one of the major rivers in Liaoning Province,the Taizi River is a typical mountainous river in China.In recent years,along with the country's vigorous efforts to promote urbanization,its water environment and aquatic life have been unprecedentedly damaged.Among them,the urban area of Taizi River in Benxi is the most serious.Due to the direct discharge of wastewater,city water dam,riparian zones serious damage,overfishing wild fish,heavily polluted tributary and other issues have caused many river ecological problems and severe degradation of river habitats.Research on ecological evolution and ecological restoration of rivers in northern mountainous river water quality could provide effective guidance for habitat restoration and ecological improvement in Taizi River.Based on field surveys and comprehensive analysis of water quality and aquatic organisms in Taizi River,this article provides an in-depth understanding of the basic water quality and distribution of aquatic organisms for Taizi River.And identifies the major water quality indicators in Taizi River.Through the study on the effect of dams and tributaries to Taizi River's mainstream water quality,this paper analyzed the impact of urbanization on the ecological evolution in Taizi River water quality.On the basis of the above research and the Bibliometrics,this thesis consulted methods on river restoration from domestic and international,and combined with the present situation of Taizi River,the geographical environment,the economic situation of Taizi River.I put forward several suggestions and implementation schemes for the ecological restoration of water quality,and this will provide effective solutions for the water quality ecological problems caused by urbanization.
