Evaluation of Ecological Water Conservancy Benefits for Lakeside Cities Based on Principal Component Analysis by GU Xiaohan, ZHU Shijie, MAO Jinqiao

“…Lakeside cities are important intersection areas of natural land,lakes and urban ecology.Poyang Lake plays an important role in regulating the water level of the Yangtze River,conserving water resources,improving local climate and maintaining water security.In order to objectively and comprehensively measure the ecological water conservancy benefits of the lakeside cities around the Poyang Lake,taking the Gongqingcheng City as a typical case and the statistical analysis as a basis,this paper puts forward the evaluation index system qualitatively and quantitatively from three aspects of economic benefits,social benefits and ecological benefits,and constructs the evaluation model by the principal component analysis method.The results show that the score of ecological water conservancy benefits of the Gongqingcheng City in 2019 is 1.253 8,the ecological quality grade is Class III,the regional economy is well developed,and the ecological and social benefits are remarkable,which are consistent with the current ecological status of the Gongqingcheng City.Therefore,the model is featured with good applicability and rationality.…”

Analysis and Recheck of Reinforcement Scheme of Dikes in a Polder by WU Juan, ZHANG Ming, LI Yansong

“…The dike reinforcement project in a polder has a total length of 8 873 m.There are some local problems along the dikes,such as the insufficient crest elevation,thin dikes,insufficient stability of dike slopes,leakage of dikes,and damaged pavement on the crest,which affect the flood control safety of dikes and cannot meet the normal operation requirements.Therefore,on the basis of analyzing the present situation and problems,targeted research on dike reinforcement design is carried out,and the design principles of dike reinforcement are put forward.Moreover,we implement the design contents,including the recheck of crest elevation,reinforcement design of dike sections,anti-sliding stability recheck of dike slopes,anti-seepage and reinforcement design of dikes,and effect evaluation.The reinforcement design scheme fully considers the actual local situation,which meets the overall flood control requirements of the river basin and is compatible with the local existing flood control projects for operation.The proposed dike reinforcement design scheme has certain universality and can be used as a reference for dike reinforcement in plain areas.…”
