Study On Land Suitability Evaluation And Improvement Strategy Of Rural Residential Areas In County Area

Under the background of accelerating the construction of ecological civilization,the implementation of territorial spatial planning is an important measure for the protection of ecological resources.The suitability evaluation of land spatial development is the basis of compiling land spatial planning.Reasonable determination of the layout of rural residential areas in land spatial planning is one of the contents of in-depth study on suitability evaluation of land spatial development.Based on the division of the suitable degree of rural settlements and the combination of policy orientation and regional characteristics,this paper analyses the problems that need to be solved in the process of utilization of rural settlements land and puts forward remedial measures to optimize the spatial distribution of rural settlements,so as to achieve the goal of land spatial planning.The rational distribution of residential areas in middle rural areas provides scientific basis.We should thoroughly study the domestic and foreign research results related to the suitability evaluation of rural residential areas and summarize and analyze them.We put forward that the research on suitability evaluation of rural residential areas needs to be supplemented and improved,further enrich the research on Evaluation indicators,scientifically define the concept of suitability evaluation of rural residential areas,and reasonably determine the suitability evaluation method of rural residential areas.Taking Dahua Yao Autonomous County(hereinafter referred to as Dahua County)in Guangxi as the research area,with the help of GIS software and guided by scientific theory,this paper makes an empirical analysis of the suitability evaluation method of rural residential areas in the county and puts forward reasonable remedial measures,which provides a reasonable basis for the allocation of land and resources in Dahua County.The main conclusions of the paper are as follows:(1)The suitability grade of rural residential areas in Dahua County is divided into five grades.Among them,the unsuitable area is 35588.20 hm~2,the critical suitable area is 74831.60hm~2,the general suitable area is 78791.89hm~2,the more suitable area is 65058.79 hm~2,and the highly suitable area is 20606.35 hm~2,which accounts for 12.95%,27.22%,28.66%,23.67%and7.50%of the total area of the county.From the overall level of the county,the suitability distribution of rural residential areas is relatively low except in the southeastern region,which is obviously restricted by topographic conditions and ecological environment.Generally,the most suitable areas and the least highly suitable areas.From the level of each township,the suitability grading structure of rural residential areas within each township is different,and the proportion of suitability area at all levels is different.(2)There are five types of rural settlements renovation in Dahua County,which are urban-rural integration,key development,internal optimization,migration and integration and special renovation.Among them,the area of rural residential areas of urban-rural integration type is 4.84 hm~2,and the main measures are as follows:(1)adjusting land use types in conjunction with land planning;(2)developing modern agriculture to enhance the driving force of economic growth;(3)helping farmers increase their income and protect their rights and interests;(4)improving the construction of public infrastructure.The area of key developing rural residential areas is1760.18 hm~2.The main measures are as follows:(1)Developing large-scale agriculture to enhance the potential of agricultural development;(2)Perfecting the construction of public infrastructure services,especially communication facilities;(3)Strengthening the construction of central villages through various measures.The area of internal optimized rural settlements is 2811.88 hm~2.The main measures are as follows:(1)control the expansion of rural SETTLEMENTS’boundaries;(2)reclamation of abandoned construction land in rural settlements and optimize the land structure;(3)increase the productivity of agricultural land,develop green agriculture and construct ecological agricultural space;(4)further promote the construction of transportation facilities.The area of relocation and amalgamation rural residential areas is 53.93 hm~2.The main measures are as follows:(1)relocation of this part of rural residential areas to highly suitable areas;(2)reclamation of relocated residential areas to increase the area of agricultural land and enhance the function of regional ecological services.The area of special renovation rural settlements is270.43 hm~2.The main measures are as follows:(1)making reasonable renovation plans to preserve the original rural style as far as possible;(2)building cultural protection bases to inherit Yao Township culture and promote tourism development.
