Reconstruction Of Rural Living Space In Hilly Areas From The Perspective Of Rural Revitalization

Rural living space is a representation of human-land relationship in the countryside,and is the main component of rural space.China has a large population base and even though the urbanisation rate of our population has increased significantly,rural living space will remain a place for rural citizens to live and a spatial carrier for agricultural production for a long time to come.For a long time,due to the lack of rural planning,the layout of rural living space has been scattered and the utilization of land for rural living space has been rough.In the context of the implementation of the rural revitalization strategy,the construction of beautiful villages has been accelerated,the construction of urban and rural infrastructures has been remarkable,the interconnection of regional urban and rural infrastructures has been basically realized,the change of rural production methods and the massive transfer of rural population have accelerated the change of rural living space,and the spatial pattern of rural living space is still dominated by natural distribution.In the context of rural revitalization,hilly areas should rely on their good ecological endowments and strengthen the development of"forestry and fruit"special industries while stabilizing food.Optimizing the land use of rural living space can provide guarantee for rural revitalization.Based on this,the thesis takes Guang’an City in Sichuan Province as the research area,takes rural living space as the research object,uses the third national land survey database and DEM data as the basis,applies the conventional Voronoi diagram method,the kernel density estimation method and the landscape pattern metrics,and uses the spatial visualization ability of Arc GIS to analyse the characteristics of rural living space pattern in Guang’an City,and introduces the MCR model to evaluate the suitability of rural living space land in Guang’an City.Finally,according to the evaluation results and the actual situation of Guang’an City,the types of rural living space reconstruction in Guang’an City are classified,and corresponding suggestions are made for the optimization of different types of rural living space reconstruction.The study shows that.(1)Only the spatial distribution type of rural life in Guang’an City is random,and the spatial distribution type of the rest of the townships and towns(streets)is agglomerative;the areas with high values of spatial nuclear density of rural life in Guang’an City are mainly located in Fei Long Town,Mang Shan Town,Leshan Town,Peng Craftsman Township,Baimiao Town,Pingtan Town,Longnui Town,Wanlong Town,Center Town,Chaoyang Street and Zhenyu Town in the western region,in addition,Longtai Town,Huaqiao Town in the northern part of Guang’an City,Yanghe Town,Yongxing Town,Hualong Street and Lushi Town in the central part of Guang’an City also have high nuclear density values.,Huaqiao town,central Yanghe town,Yongxing town,Hualong street,Lu Shi town nuclear density value is also larger.In contrast,the estimated nuclear density values in the eastern part of Guang’an City are relatively small;the rural living space map of Guang’an City is irregularly shaped,and the boundary shape is more complex,which is not conducive to the intensive management of rural living space in the region;at the same time,the current situation of rural living space land in Guang’an City has three problems:the area of rural living space land is over the standard,the contradiction between human and land is intensified,the land utilization rate is low,and the layout of rural living space is scattered and lacks centripetal guidance.(2)Topographical factors such as elevation,slope and slope direction,and location factors such as distance from water,roads and administrative centers have a great influence on the layout of rural living space in Guang’an.The area of rural living space land in Guang’an is the largest in the range of elevation 82-353m,slope 5°-10°,slope direction is sunny,within 500m from water,within 1000m from road,and within 1500-3000m from administrative center.(3)On the whole,the land use conditions of rural living space in Guang’an are good.Based on the suitability evaluation results,Guang’an City is divided into five suitability zones:highly suitable zone(329355.75hm~2),more suitable zone(147693.27hm~2),generally suitable zone(93679.13hm~2),unsuitable zone(42686.41hm~2)and extremely unsuitable zone(20496.45hm~2).(4)Based on the results of the suitability zoning,the types of rural living space in Guang’an were classified into four types:suburban integration(4186.51hm~2),agglomeration enhancement(20483.48hm~2),controlled development(11772.10hm~2),and relocation and demolition(3426.27hm~2).The rural living space in the suburban integration category can be used as a potential reserve area to reduce the population pressure in the town and for economic development;the rural living space in the agglomeration and upgrading category can be used as an area to move in for the rural living space in the relocation and demolition category in the future;the rural living space in the controlled development category can be renovated and upgraded on its original scale according to local conditions or relocated and demolished after its spontaneous decline;the rural living space in the relocation and demolition category can only be relocated and merged into the The relocation and demolition of rural living spaces can only be done by relocating to areas with better living conditions,strong environmental carrying capacity,and complete supporting infrastructure.
