Land Zoning Based On Production-Living-Ecological Functions Of Municipal Level

At present,much attentions have been paid on the the development of land use function of the production-living-ecological space by our country.The functional division based on the land-production-living-ecological space can solve the problems arised from the inconsistent develepment between social economy and land use,and can preserve the spatial diversity of the land.In our country,the study of functional division based on the land-production-livingecological space is still in the infancy stage lacking the support of high-precision basic data.Moreover,in the third national land survey,it is proposed that we should establish a data evaluation and analysis platform,conduct networked collection of information,and integrate land resources into an information database to facilitate the analysis and utilization of land resources.In this study,we chose Zibo City as research area and established a data evaluation and analysis platform.on the basis of production-living-ecological space,functional zoning of Zibo City was conducted and an indicator system for land space zoning was constructed combined with multi-source data.The index analysis and evaluation of production-lifeecological space was carried out by the triangular model and the coupled coordination model.Then,we calculated the index of the criterion layer of each district according to the TOPSIS;and conducted the zoning via natural break point method.Finally,through the remote sensing interpretation of Zibo City,the landscape pattern analysis was carried out based on the production-living-ecological space;comprehensive analysis of the zoning results were obtained;and future development suggestions were proposed.The main research conclusions of this paper are as follows:(1)Construct an indicator evaluation system for production-living-ecological space function zoning.This paper constructed an evaluation index system based on production,life and ecological space,and selected six criterion layers including agricultural production,secondary and tertiary industry production,ecological balance,resource security,social security and life service.On the basis of the criteria layer,we further refined the indicators,integrated the functional characteristics of each space,and finally selected 23 indicators including cultivated land area,NDVI,regional GDP,per capita income of residents,etc.(2)Comprehensive evaluation of the function of production-living-ecological space in Zibo City.The time series characteristics of Zibo City are basically in the order of production function>life function>ecological function.The life function reached 0.9 in 2014 at a higher level and is still increasing.But the ecological function is the weakest.According to the analysis of the triangular model,Zhangdian District,Linyi District,Luanchuan District and Zhoucun District have experienced four stages of changes,and the production and living function space have better developed,but the development of the ecological function space is weak.Gaoqing County,Huantai County and Wuyuan County have undergone three stages of changes.The ecological and production space functions in these three areas have developed well,and the development of living function space is weak,which needs to be rectified and improved.The coupling degrees of the districts and counties in Zibo City were in a relatively low stage in 2005,and reached a stage of high coupling development in 2014.However,in terms of coupling coordination degree,the values of each district and county are low,indicating that there are still contradictions and conflicts in the land use process of Zibo City in production-life-ecological space.(3)Land functional zoning based on production-life-ecological space.The agricultural production function of Gaoqing County and Huantai County are relatively high,reaching 0.58 and 0.56.The production capacities of the second and third generations in Lizi District and Luanchuan District are relatively high,reaching 0.42 and 0.48.Boshan District and Yyuan County have strong ecological balance functions and resource security.Zhangdian District,Zhoucun District and Linyi District have strong social security functions and life service functions.According to the our analyses,Zibo City is divided into three major functional areas:Northern Plains Agricultural Production Zone,Central Life Development Zone and Southern Ecological Economic Zone.The status quo of each functional zone is analyzed.(4)Comprehensive analysis and development proposals after the land space division.Through the analysis of landscape pattern,the production space of Gaoqing County andHuantai County is the best.The number of patches,patch density and separation index are lower and the degree of polymerization index is higher which indicate that the overall landscape of production space in the area charicters high connectivity and low landscape fragmentation showing an aggregated distribution.Zhoucun District,Zhangdian District,Luanchuan District and Linzi District have slower development of ecological space and low degree of landscape fragmentation.But both production and living spaces have developed well,and the development of living space has the highest suitability.Accoding to our analysis,we suggested that Zibo City should construct a core development zone with the central living production zone as the driving axis and Zhangdian District as the center to promote the development of horizontal and vertical zones,and form a comprehensive and sustainable development pattern of the national land space that can be linked to the city.
