| Industrialization and urbanization in our country is developing rapidly,in promoting the system of material civilization,civilization and the development of the humanistic spirit at the same time,there are different levels of problems: production,living space constantly occupy ecological space,increasingly serious environmental pollution,ecological system damage;The urban space is highly expanded and the land is not intensive,the industrial structure is lagging behind,and the proportion of the tertiary industry is low.The unreasonable allocation of urban and rural infrastructure and the imbalance between urban and rural welfare supply lead to the contradiction between ecological environment and social and economic development.Current of zhengzhou is a comprehensive accelerate the construction of national center city,therefore need to constantly enhance the level of ecological construction,promote the city "Production-Living-Ecological" Spaces overall layout,"Production-Living-Ecological " function coordinated development,solid foundation for the construction of national center of zhengzhou city.Optimizing the spatial pattern of "Production-Living-Ecological Spaces" and promoting the integration of urban functions become an important task to maintain sustainable land use and social and economic sustainable development.Therefore,based on the analysis of zhengzhou "Production-Living-Ecological" Spaces spatial pattern of the internal contradictions of the first to measure the abilities of zhengzhou city resources environment for capacity,economic activity and social development of the "good" space bearing capacity evaluation,building in zhengzhou city "Production-Living-Ecological Spaces" bearing capacity evaluation index system of urban and rural space,from the perspective of functional integration to build "Production-Living-Ecological " space multifunctional evaluation researches on the two aspects of content,combined with the two aspects of research urban districts and counties function orientation and optimization development direction,feasibility to "grow" space optimization Suggestions.The main conclusions are asfollows:(1)In 2015,the current state value of ecological carrying capacity of all districts and counties in zhengzhou exceeded the carrying capacity value of the ideal state,of which the two or seven districts,the upper block and the high-tech zone were more overloaded than those in other counties.The ecological carrying capacity of the surrounding counties is not serious compared with that of the surrounding area.In2015,the current status of production capacity of each district and county in zhengzhou is higher than the ideal value,and it is in overload condition.Zhongmou county,central urban area and high-tech zone,jingkai district,zhengdong new district,aviation port area overload situation is serious;In 2015,the current status of life carrying capacity of 15 districts and counties in zhengzhou was lower than the ideal value,and the actual value of zhongmu county was higher than the ideal value,but the overload situation was not serious.(2)The areas with high ecological maintenance function value in zhengzhou are successively dengfeng,gongyi,huiji district,zhongmou county and xingyang,and the proportion of ecological land has a large influence on ecological maintenance function.Economic development function value is relative taller area mainly concentrated in the central city,the area of agricultural production function strong concentration distribution in surrounding the central city and counties,the spatial distribution of agricultural production and economic development presents basic instead of spatial pattern;The areas with greater function value of residential areas are jinshui district,xinmi,dengfeng,xinzheng and zhengdong new district.Social security function strong areas of zhengdong new district,jinshui district,tube city,high-tech zone,for residential homes function and the social security function is influenced by economic development function,so the present certain relevance.(3)"Production-Living-Ecological Spaces" feasibility optimization Suggestions and strategies for specific:(1)Optimize Optimization of external and internal ecological space;(2)The combination of reasonable planning industrial production space,promote the fusion of the production space and living space;(3)Building a coordinated interaction between production life space,to establish urban and rural complex ecosystem.In view of the city in different function type,put forward theconcrete leading,agricultural production function leading to ecological function,economic development leading,residential homes leading regional functions improve advice. |
