Study On The Construction Of Rural Greenway Network In Southern Jiangsu Province Under The Dual Guidance Of Ecology And Recreation

With the speeding up of the new urbanization in our country and the advancement of the Yangtze river delta integration strategy,the development of rural areas in southern Jiangsu is quickly.Due to the change of external natural environment and the influence of human activities,the contradiction between the deterioration of environmental quality caused by the rapid development of rural areas and the increasing recreational needs of residents is becoming increasingly prominent.On the one hand,rural areas in southern Jiangsu are the pilot areas of new-type urbanization in China.The interference of artificial construction is constantly strengthened,and the problems such as river network shrinkage,habitat fragmentation and characteristic landscape loss of water towns are prominent.On the other hand,with the improvement of people’s material living standard,urban and rural residents’ demand for leisure and recreation has gradually increased,and the environmental quality requirements for leisure and recreation have also been improved.At present,the construction and planning of greenway network is gradually changing from single orientation to dual orientation and multi-objective.The compound greenway network under the dual orientation of ecology and recreation can coordinate the relationship between rural ecological environment protection and recreational needs of rural residents,which is an important way to promote the sustainable development of rural areas.Therefore,this study takes rural areas in southern Jiangsu province as the research object,proposes a systematic approach to construct the rural complex greenway network under the dual guidance of ecology and recreation.With the goal of protecting the ecological environment and improving the recreational function of rural areas,this study provides reference for the construction of rural greenway network in southern Jiangsu Province.This study firstly sorts out the relevant research on greenway network,analyzes the problems faced by the rural greenway network in southern Jiangsu,and summarizes the construction principles of the rural compound greenway network in southern Jiangsu.This paper analyzes the relationship between ecological greenway network and recreational greenway network in the south of Jiangsu province from the structural and functional levels,and provides the basis for the construction of complex greenway network under the dual orientation of ecology and recreation.Secondly,based on the theories of human settlement environment,environmental behavior,landscape ecology and other related theories,the greenway network under the single orientation of ecology and recreation was constructed,and the compound greenway network under the dual orientation of ecology and recreation was constructed from the perspectives of structural coupling and functional optimization.Finally,taking Lili town in southern Jiangsu as an example,the paper applies the construction of rural greenway network in southern Jiangsu under the dual guidance of ecology and recreation.The main contents of this study are as follows:(1)Based on the analysis of the problems facing the rural greenway network in southern Jiangsu,it is concluded that the rural greenway network in southern Jiangsu has strong fragmentation and insufficient recreational resources,and there are challenges in the construction of the greenway network.The relationship between ecological greenway network and recreational greenway network in rural areas of southern Jiangsu province was studied from structural and functional levels,and clarify the construction path of the composite greenway network under the dual orientation of ecology and recreation.(2)In order to coordinate ecological environmental protection and people’s recreational needs,this paper studies the construction of a rural complex greenway network in southern Jiangsu province under the dual guidance of ecology and recreation from the structural coupling and functional optimization aspects on the basis of ecological and recreation greenway network.Construction of Ecological greenway network: Using MSPA and In VEST model identify ecological sources,the MCR and gravity Model are used to extract ecological corridors to construct ecological greenway network.Construction of recreation greenway network: using recreation demand and resource evaluation identify recreation nodes and extract recreation corridors based on suitability evaluation to construct recreation greenway network.Construction of complex greenway network under the dual orientation of ecology and recreation: Plan the layout of complex greenway network from the structural coupling level by using coupling coordination model and network structural index;At the level of function optimization,combined with rural characteristics of water network,the compound greenway network was optimized from three aspects: node protection,corridor connectivity and network integration.(3)Taking Lili Town of Suzhou city as an example,it is feasible and typical to construct a complex greenway network in Lili town under the dual guidance of ecology and recreation.At the structural coupling level,according to the coupling coordination degree between ecology and recreation functions,the composite source area was divided into ecological dominant type,recreation dominant type and balanced type.Through network analysis method,the optimal superposition scheme of greenway is selected to plan the network layout of compound greenway in Lili Town.At the function optimization level,the path optimization of the complex greenway network in Lili town is carried out from three aspects: node layout is balanced,corridor control is refined,and network function is complex.
