Research On Stream Daylighting Strategy Based On Comprehensive Benefit Evaluation

Urban stream daylighting is an important part of urban water environment restoration.This paper mainly focuses on the topic of stream daylighting and carry out multi-dimensional comprehensive research.Firstly,this paper summarizes the academic and practical background of stream daylighting,summarizes the existing research and practice cases,constructs the method framework and practice process system of urban stream daylighting.Secondly,the main urban area of Wuxi city is selected as the case study object.On the basis of the research on the history and current environment of the water system in the city,a work framework for the stream daylighting in the main urban area of Wuxi city is proposed.The work framework mainly includes the research of region scale level and site scale level.Based on the engineering feasibility evaluation and environmental benefit prediction evaluation,the preliminary site selection and overall restoration strategy of stream daylighting in Wuxi are completed.The study of site scale level focuses on the analysis of the stream daylighting at the site scale,the research completes several specific restoration schemes of the stream daylighting.
