Study On The Delimitation Of The Ecological-production

In the process of rapid urbanization,China's resource constraints have continued to intensify and the pressure on the ecological environment has increased,and the territorial development and protection are facing severe challenges.With the continuous expansion of urban and rural construction land,the space for agriculture and ecological land is being squeezed,the contradiction between construction development,agricultural production and ecological protection become more prominent.The uncoordinated tension attaches great concern from the public over food security and ecological security.The policies of space development are faced with a difficult choice,and the pattern of land space development needs to be optimized.In view of this,the government proposes to scientifically delimit ecological-production-living space in order to optimize the spatial structure and establish a harmonious relationship between protection and development through the definition of the boundaries of the ecological-production-living space.In order to scientifically optimize the pattern of land use and development,it is necessary to determine the rational proportion of the ecological-production-living space,which is the important means of spatial planning and modernization governance.On the premise of guaranteeing the safety of ecological pattern and meeting the needs of development,delimitation of the ecological-production-living space provides a theoretical foundation and technical support for making different land space management policies,which has great influence on realizing the new urbanization strategy and promoting the construction of ecological civilization.Henan,as a big province in agriculture development,is one of pilot provinces of spatial planning,so it's significant to take Henan province as a typical case to delimit the ecological-production-living space in this paper.Ecological-production-living space is the important means of realizing space control and optimizing the spatial pattern which is mentioned in the policy document.However,there are still many issues that need to be explored,such as how to truly put the delimitation of the ecological-production-living space into concrete practice.And agricultural production and life functions are highly coupled and indistinguishable.Therefore,this paper takes the complexity of spatial functions into consideration,which means the existence of cross-functional and fuzzy areas in the land space.In view of this phenomenon,this paper divides the ecological-production-living space into single-space and complex-space,and then further classifies the complex elastic space based on land suitability assessment to solve the problem of undefined boundary of space due to the spatial functional compounding.Delimiting the ecological-production-living space makes the coordinated and sustainable development of urban development,food security,and ecological protection.And it is conducive to the implementation of different land space management policies for different functional space and the informatization and refinement management of land space.The research results show that:(1)The hierarchical classification method is used to determine the classification system of ecological-production-living space,and the detailed classification and delimitation of complex space is conducive to distinguishing the functional connotations of different spaces and then implementing effective spatial management.(2)According to the results of the delimitation,the ecological protection space area is 10973.32 k12,the production space area is 73345.04 km2,and the living space area is 2845.30 km2.In the complex space,the area of space which is regarded ecological protection function as the dominant function accounts for 26.34%of the total area of Henan Province,the area of ecological-production space is 36286.84km2,the area of ecological-living space is 7428.53 km2.The area of space which is regarded agricultural production function as the dominant function accounts for 11.86%.The area of production-living space is 11220.l4km2,the area of production ecological space is 8459.28km2.The area of space which is regarded construction development function as the dominant function occupies 8.48%,the area of living-production space is 9766.80km2,the area of living-ecological space is 4305.26km2.The area of the space which is suitable for all of the three function is 1340.06km2,accounting for only 0.81%of the total area of Henan Province.(3)According to the theoretical basis and practical requirements,this paper uses combination of qualitative and quantitative research methods to delimit ecological-production-living space,which shows the delimitation has great potential for application and plays an important role in the future spatial planning and management.
