Research On Layout Optimization Of Rural Residential Areas In Shufu County Based On GIS

This paper takes Shufu County of Kashgar as the research area,collects relevant statistical data and data,obtains relevant data such as the digital elevation map and land use planning data of Shufu County,and uses the collected data in the spatial analysis function of ArcGIS software.Support analysis of slope and slope data of Shufu County and buffer analysis of river and road data.In further research,the spatial distribution characteristics of rural settlements in Shufu County were analyzed by the calculation of landscape index and the results of conventional Tyson polygon maps.The suitability evaluation index is established to determine the suitability evaluation,and the classification of rural residential areas is classified by the suitability evaluation results,and the optimization plan for the rural residential area layout and urban and rural development and new villages in Shuilian County is proposed.Provide reference for rural settlements and centralized living of villagers.The main content and conclusions are as follows:According to the comparative analysis of the rural residential areas in Shufu County in 2009 and 2014,we can see the changes in the layout of rural residential areas.The analysis shows that the scale of rural residential areas in 2014 has expanded significantly.The main form of conversion is from bare land to rural residential areas.The main conversion form of rural residential areas with reduced scale is urban construction land.Comprehensive application spatial analysis,conventional Voronoi diagram,landscape pattern analysis and other methods are used to derive the distribution characteristics of rural settlements and the impact degree of factors affecting the distribution of settlements.The research results show that the rural residential areas in Shufu County belong to a highly clustered distribution,which is closely related to the natural geographical conditions,the convenience of transportation,and the law of resource allocation.Through the buffer analysis,the results show that the rural residential areas are larger in scale and relatively concentrated in the range of 500-1000 m from water resources,roads and towns.Atthe same time,the distribution patterns of rural residential areas in Shufu County are summarized as follows: satellite distribution,band distribution,block aggregation and free distribution.In this study,six indicators were extracted to establish a suitable evaluation system for rural residential location.According to the influence of various index factors on the distribution of rural residential areas,the suitable areas were divided into the following five types: suitable area,suitable area,and general suitable area.Less suitable areas and unsuitable areas.Finally,according to the results obtained,the types of remediation of rural settlements are divided.On the basis of a series of results,it provides reasonable and reliable advice for the organization of scattered and disorderly rural residential areas.Finally,the types of remediation of rural settlement optimization are: urbanization,development expansion,recommended retention,and migration consolidation.According to the actual situation of Shufu County,the combination of quantitative and qualitative methods is used to divide the rural residential area optimization plan and remediation suggestions.1 For residential areas suitable for urbanization,it is recommended to plan close to the urban and urban construction land clusters,and include the future of rural residential areas as urban land.2 Develop extended rural residential areas to propose key development strategies,and guide small-scale,discretely distributed residential areas to be gathered in the central village.3 It is recommended that the reserved rural residential areas first ensure that they will not be expanded again.The follow-up plan will be gradually approached to the central village or merge with the larger rural residential areas around it.4 Relocation and consolidation of rural residential areas will be abandoned by means of relocation and other means,and will be moved closer to the central villages with better environmental conditions,contributing to land planning and effective land use.
