Study On The Evaluation Of The Use Of Ecological Corridor In Zhengzhou Based On The Background Of "Urban Double Repair"

Based on the "urban double repair" policy,the construction of urban ecological corridor is in full swing.Urban ecological corridor plays an indispensable role in the life of urban residents,and its design rationality and convenience become the main issues of research.Since 2012,Zhengzhou has built 69 ecological corridors,with a total length of 3588 km and a total greening area of 300 million square meters,initially forming a network ecological corridor pattern of two rings and 31 radiation.Through the research on the evaluation of Zhengzhou ecological corridor after its use,to promote its optimization and construction,and to provide reference for the construction of the ecological corridor after,has become an important problem to be solved.This paper takes the urban ecological corridor of Zhengzhou Central City as the research object,through the field investigation and analysis,constructs the evaluation system of urban ecological corridor use,analyzes the current situation and existing problems of Zhengzhou urban ecological corridor use,and carries out targeted optimization strategy research,in order to provide theoretical reference for the design and construction of urban ecological corridor in the central city.The thesis is divided into three parts.The first part is to raise questions,explain the background of the topic,the purpose and significance of the research,the existing theoretical results,research content and framework.The second part is the analysis of the problem,respectively from the macro,meso,micro perspective of Zhengzhou urban ecological corridor qualitative and quantitative research.First of all,the paper defines and analyzes the concepts of "urban double repair",urban ecological corridor and related concepts.From a macro perspective,it is found that under the current background of "urban double repair",urban ecological corridor faces a series of common problems,such as weak ecosystem network,serious damage to ecological environment,real urban cultural memory,and lack of humanistic care.Secondly,from the perspective of meso analysis,it is concluded that Zhengzhou urban ecological corridor has begun to take shape,but there are many existing problems.Then,from the microcosmic point of view,the fuzzy comprehensive method is used to evaluate the satisfaction of the four criteria layers and twenty-four factor layers of the ecological corridor of Huayuan Road,Dongfeng Road,navigation road and Zhongyuan Road in Zhengzhou.The analysis shows that the users have high recognition of the natural environment of the ecological corridor in Zhengzhou and the service function of the ecological corridor in Zhengzhou The evaluation of cultural attribute and later maintenance is low.The third part is to solve the problem,combined with the investigation and data analysis,the paper puts forward targeted optimization strategies in plant configuration,space construction,service facilities,cultural refining,management and maintenance.And select the typical section of Huayuan road ecological corridor to optimize the design scheme,guide the design from the aspects of urban ecological corridor space repair and urban ecological corridor ecological repair,and carry out the detailed design from the design concept,design drawings,as well as plant configuration,logo design,seat design,trash can design,lighting design and other details,so as to promote the city of Zhengzhou The ecological restoration of the ecological corridor,giving full play to the regional cultural attribute,realizes the multi-dimensional urban renewal design.
