Study On The Optimization Strategy In The Network Space Of Green Infrastructure Under Ecological Management And Control

China has a number of cities began to practice the practice of ecological control,to explore how the process of rapid urbanization in the city to keep the "bottom line." At present,the ecological control system is often faced with the following problems: First,the planning of the ecological control area and adjacent to the centralized construction of the ecological space in the composition of the ecological space network is still a lack of connectivity research,the second is a single control And the lack of protective measures will also cause the ecological differences between urban and rural areas,urban residents can not enjoy the ecological space of the service function.In this context,through the study of the characteristics of the green infrastructure network,the author is trying to analysis the ecological control area and centralized construction area of the complete layout of the ecological network space,based on ecological control planning,and research under the control of the ecological space for the city and even regional which can play the recreational function and production function,and through the regulations,administration,economy,technology,policy several aspects to study the green infrastructure network implementation and management mechanism.This article focuses on the contents bellows:?.A Study on the Theoretical Basis of Green Infrastructure and Ecological ManagementFirst of all,the author analyzes the relationship between the core structure,the target system,the spatial scale and the carrier of the green infrastructure planning and the ecological control planning.It is concluded that the main body of the two types of planning is the urban and rural ecological network space,The former focuses on spatial optimization and functional research,the latter focuses on the conservation of ecological space research,although the role of the two types of planning is not the same but the function is relying on each other to jointly build urban and rural ecological space system,this part is not only follow-up study The author also provides a theoretical basis for the green infrastructure planning under the ecological control of the case.Secondly,the author summarizes the three aspects of the green infrastructure network based on the ecological control under the three dimensions of time dimension,spatial dimension and action subject.Characteristics,and then from the green infrastructure network elements,green infrastructure network construction technology,green infrastructure network optimization theory based on three aspects,for the subsequent case of green infrastructure network optimization to provide the relevant theoretical basis.?.Study on the Optimization of Green Infrastructure Network under Ecological ManagementTaking the northern city of Wuhan urban development area as an example,the author divides the landscape elements into the fields of farmland,forest and grassland,water,construction land and bare land by ENVI,and in Fragstats4.0,the landscape pattern index before optimization is calculated,and the ecological sensitivity analysis of ArcGIS is used to analyze the status quo within the planning scope.The results show that the ecological environment in the whole planning area is better,but the centralized construction area The construction of the scope of the higher degree of the urgent need to enhance the construction of various types of ecological patches between the connectivity;and then based on the principle of connectivity to the status of green infrastructure network space to sort out through the place and connecting the building will be And the ecological space is connected with the ecological base.Finally,after the optimized plaque,the optimized landscape pattern index is calculated in the Fragstats4.0 software,and the final CONNECT optimization is 38.10%,and LSI is improved up 14.68%,SHDI improved 7.02%,indicating that play a major ecological role is still the ecological System area range,but by improving the construction area of ecological network can be greatly improved connectivity across ecological space.?.Study on Recreational Function and Industrial Function of Ecological Space under Ecological ManagementBased on the the landscape style and the status of industrial production in the ecological control area,the author puts forward the planning of the recreational function and the industrial function of the whole ecological network based on the control of the construction content and the construction quantity in the planning area.In the recreational planning,according to the status quo delineation of the "three corridors,four heart two areas" structure,and delineated nine country parks system;in the industrial function planning plate,the author based on the country park system,set up projects in different parks Point,through tourism and agricultural tourism industry to promote the development of the industry.?.Study on the Implementation Mechanism and Long-term Mechanism of Green Infrastructure NetworkFirst of all,I put forward the establishment of ecological management system,the establishment of legislation to protect the system,the construction of ecological communities and ecological villages,the establishment of public participation in the four aspects of the implementation of the green infrastructure protection mechanism.Secondly,it discusses the technical methods of the implementation of green infrastructure space in the ecological control area and the urban construction area,and discusses the solution strategy of the corresponding problem from different perspectives of technology,economy and law.Finally,In order to protect the dynamic mechanism of the long-term health and stability of ecological space,the corresponding ecological compensation mechanism and dynamic supervision mechanism should be established to cope with the change of urban land use structure.
