Study On Evaluation And Optimization Countermeasures Of Rural Human Settlements Quality In Oasis

The quality of rural human settlement environment plays an important role to measure the level of rural regional development.To scientifically understand the basic connotation,regional differences and formation mechanism of rural human settlement environment,and to explore the type division and optimization strategy of human settlement environment quality are not only the exploration of new areas of rural geography,but also the objective needs of the effective implementation of Rural Revitalization Strategy and rural regional development.Jinchang is a heavy industrial city in China.Its economic development is in the forefront of Gansu Province.Its ecological environment is relatively fragile.It is of positive practical significance for the future development of Jinchang to study the current situation and regional differences of rural human settlements construction.Combined with land use data and remote sensing data,the ecological environment quality was evaluated.The rural living environment is evaluated from three dimensions: living environment,production environment and ecological environment,which make the evaluation system of rural human settlement environment with comprehensive,more accurately reflect the level of Jinchang City rural human settlement construction.We uses exploratory spatial analysis method to analyze the spatial differentiation characteristics of sub-system and comprehensive system of rural human settlement environment administrative villages,and further uses Pearson correlation measurement method and geographic detector method to explore the influencing factors from three aspects of natural geographical conditions,socio-economic conditions and social capital attributes,then puts forward the regional division of Jinchang city optimization strategy.(1)There are significant regional differences in the living environment subsystem,production environment subsystem and ecological environment subsystem construction level of rural human settlements in Jinchang city.The quality of living environment is significantly higher than other areas in urban surrounding areas,showing a spatial pattern of “high in the north and low in the South”.The overall level of production environment quality is lower.The production environment in Shuangwan town and Xinchengzi town is superior to other areas.There are obvious regional differences in the quality of ecological environment.The eastern region has abundant water resources,flat terrain,good climatic conditions and terrain advantages,and the overall ecological environment is better than other regions.(2)The quality of rural human settlements in Jinchang city varies greatly from region to region,and the overall level is not high.The high-level areas are mainly distributed in the north,accounting for only 11.27% of the research area.The general level areas are distributed around the high-level areas and high-level areas,mainly in Zhuwangbao town and Shuiyuan town in the East,accounting for 47.06% of the total.The comprehensive system of rural human settlements environment presents obvious spatial differences,and generally presents the spatial pattern of “high in the north and low in the south”.The higher-level areas distributed in the northern region,forming a large hot spot,which is mainly high-high value aggregation type.the construction level of human settlements in the southern mountainous areas is relatively low,forming three large cold spots,which is mainly low-low aggregation type.(3)From the three dimensions of natural geographical conditions,social economic conditions and social capital attributes,nine indicators of influencing factors of rural human settlements environmental quality are selected.The results of Pearson correlation and fa geographical detector show that the distance from the center of the city,the average altitude,the per capita cultivated land area,the collective economic income of the village and the number of villagers’ Congress have a significant impact on the quality of rural living environment in Jinchang.The results of the interaction detection of geophysical detectors show that the interaction and coupling of different factors have a great influence on rural human settle environment quality.(4)According to the comprehensive evaluation and influencing factors analysis of rural human settlements environment quality,Jinchang is divided into four major areas and 9 secondary areas.Based on the principle of the integration of rural residential environment and the principle of differentiation,the paper puts forward the corresponding construction emphases and optimization strategies for the common characteristics and main problems of each sub district.
