| Since the reform and opening up,with the rapid development of industrialization and urbanization,China’s economy and society have undergone significant changes,according to the 2021 Seven Census data,China’s urbanization rate has reached 63.89%,becoming a city-based country,but the development of the vast rural areas is relatively backward.Compared with the developed areas in the east,the rural development of the western plateau region faces problems such as poor ecological environment,backward economy,small village size,and weak infrastructure.On the one hand,the altitude of the western plateau region is higher and the terrain is more complex,which is not conducive to the construction of infrastructure such as roads and the lives of residents.On the other hand,the western plateau area is sparsely populated,the production mode is mainly animal husbandry,and the industrial development is relatively backward.The development path of villages in the plateau area should be combined with the characteristics of the plateau area,a reasonable evaluation system should be constructed,the current situation of the village should be reasonably evaluated,and the potential of village development should be tapped to promote the development of the village.Taking Angren County,Tibet Autonomous Region as an example,this study studies the current situation of Angren County from three aspects: natural situation,social and economic development and spatial pattern,understands the distribution characteristics and existing problems of villages in Angren County,takes the administrative village as the evaluation unit,and evaluates the suitable construction of village land,the current situation of village development and the potential of village development in Angren County,based on the theory of ecological niche suitability,ecological niche posture theory and ecological niche expansion and compression theory,and classifies the villages.According to the results of the hierarchical classification of villages,the development path of villages is proposed.The main research contents and conclusions are as follows:（1）Based on the theory of ecological niche suitability,combined with the characteristics of villages in plateau areas,starting from the three aspects of site conditions,production conditions and ecological conditions,an evaluation index system for ecological niche suitability of village land is constructed.The study found that the overall suitability of land niche in Angren County was poor,and the spatial distribution of land niche suitability was obvious.（2）Based on the theory of ecological niche,from the four aspects of location conditions,village scale,facilities and economic level,a village ecological niche evaluation system is constructed to calculate the width of village ecological niche and the compression degree of ecological niche expansion.The study found that the ecological niches of the villages in Angren County were centered on the central urban area and decreased in descending order to the north.The overall degree of micro-expansion and compression of ecological niches is low,and the spatial distribution of the expansion and compression of village ecological niches is quite different,indicating that there is a situation where the development status of the village is low but the development potential of the village is large,or the level of the development status of the village is high but the development potential of the village is small,indicating that the village should be managed differently.（3）Based on the ecological niche suitability and ecological niche results,185 administrative villages in Angren County were graded,and the villages were divided into four types: high-level,medium-level,low-level and unsuitable for development,and the villages were classified based on the results of ecological niche expansion and compression,and the villages were divided into five types: characteristic protection,agglomeration and promotion,remediation and optimization,transformation and development,and relocation and merger.According to the idea of village classification and village classification,the differentiated development path of Angren is proposed.Figure [22] table [22] reference [81]... |
