Study On The Spatial Variation Characteristics And Conflicts Of Living-production-ecological Space In Kunming

With the acceleration of urbanization,the intensity of people’s development of land resources has gradually increased.During the process,the function of land has changed,and the contradiction between life,production and ecological space is becoming more and more prominent,leading to the intensification of space conflicts.Therefore,it is of great significance to study the spatial pattern and the situation of space conflicts of living-production-ecological space for the rational use and sustainable development of national space.The article takes Kunming city as the research area,based on the land use data in 2000,2010 and 2018,and divides the land space into production-ecological space(referring to space with production function as the main and ecological function as the supplement),living-production space,ecological-production space and ecological space.Based on the methods of spatial transfer matrix,dynamic change model and superimposing terrain factors,the spatial pattern and evolution characteristics of livingproduction-ecological space in Kunming were analyzed,and the spatial conflict measurement model was constructed according to the landscape ecological index.Analyze the differentiation of the conflict level on different spatial types and terrain gradients,divide the area to analyze the influencing factors of the conflict and put forward corresponding optimization suggestions.The main conclusions are as follows:(1)The spatial pattern and evolution characteristics of living-production-ecological space in Kunming.(1)The ecological space dominates in the Kunming City’s livingproduction-ecological space,followed by the production-ecological space,and the area of living-production space and ecological-production space is small.(2)The dynamic change of living-production space is the most active,there is a mutual transformation between ecological-production space and production-ecological space,and the change of ecological-space is relatively stable.(3)The distribution of different space types on the terrain gradient is quite different.The production-ecological space is mainly distributed in the area of 1500-2500 m and 0-25 ° slope.The living-production space is mainly distributed in the area of 1500-2000 m and the slope is less than 15 °.The spatial distribution of the ecological space is wide and has obvious distribution advantages in areas with high altitude and steep slopes.The ecological-production space is mainly distributed in areas with an altitude of less than 2000 m and a gentle slope.(2)The spatial conflict and differentiation characteristics of living-productionecological space in Kunming.(1)The level of spatial conflict in living-productionecological space in Kunming City is dominated by the general level,accounting for more than 70%.During the study period,there was conflict intensification in general.The intensity of conflict increased significantly during 2000-2010,and the change was milder during 2010-2018.(2)The conflict levels of different space types from high to low are: ecological-production space,production-ecological space,living-production space,and ecological space.(3)The level of regional conflicts between low t terrain and lower terrain levels is higher,and it shows the characteristic that the level of conflicts decreases as the terrain level increases.(3)Influencing factors and optimization suggestions for the spatial conflict of living-production-ecological space in Kunming.The limitation of terrain conditions and the large increase of urban population are the important reasons for the spatial change and the intensification of conflicts in Kunming.According to the influencing factors,the research area is divided into ecological-production functional area,productionecological functional area,and living-production functional area,and corresponding zoning optimization suggestions are proposed.
