The Study Of Spatial Pattern And Driving Mechanism Of The Counties Poor Villages In Southwest

Poverty is an objective phenomenon that runs through the historical process of human society development. It can solve the problem of poverty in rural areas, and eliminate poverty from the space, and it will be the key problem of building a well-off society in an all-round way. In southwest area of China, due to historical reasons, geographical location, ecological environment fragile factors, poor villages contiguous distribution and a closed development, It has been a major factor in economic and social development and building a moderately prosperous society in China’s western region of. And in recent years, due to the frequent occurrence of poverty population, agricultural development excessive, earthquake, rocky desertification, mudslides and other natural disasters, many areas into the vicious circle of "Poverty alleviation—Out of poverty—Re-poverty—Re-poverty alleviation".This article distribution for counties poor villages in Southwest China spatial pattern and geographical factors relations in southwest China as the research object to the county as the basic unit, based on ArcGIS spatial analysis tools integrated into the kernel density and ESDA, study spatial distribution of poor villages and spatial patterns, explore the relationship between the spatial distribution pattern and geographical factors between counties poor villages, and then search for sustainable poverty alleviation countermeasure counties poor villages in Southwest China from space, through the analysis of obtained conclusions are as follows:(1)Countiespoverty village in southwest overall spatial distribution is extremely uneven, there are seven obvious agglomeration district, including Chongqing Northeast-Northeastern Sichuan, Chongqing Southeast-Eastern Guizhou, Southeast Sichuan-Northwest of Guizhou-Northeast Yunnan, Guangxi Northwest-Southwest of Guizhou-Yunnan Southeast, Eastern of Guangxi, Western of Yunnan, Western Sichuan area,the core-periphery of poor villages dotted distribution is more obvious; regional poverty village spatial distribution characteristics, poor village of the provincial geographic concentration index for 47.75, indicating that southwest poverty village space distribution is more centralized, regional distribution is not balanced. Large number of poor village county mainly concentrated in the southwest region in central, Eastern and northeastern regions, and a focus on contiguous distribution, many poor villages in Yunnan and Guangxi in the southern area of the county was patchy distribution, the Chengdu Chongqing urban agglomeration line in the central and east of Sichuan Basin, the central Yunnan Basin area is "0" village impoverished county centralized distribution area.(2) Southwest county poverty village Global Moran’s I statistic was 0.591448, reflecting the county distribution of poor villages in southwest region there was a positive correlation between, has many poor villages and other county also has more poor village county adjacent, and in space the overall aggregated distribution characteristics; spatial association in the impoverished village, southwest poor village the distribution of highly concentrated, less impoverished village more counties and povertystricken village or no county has concentrated distribution, and there was a High-High 、 Low-Lowgathering area, whereHigh-High aggregation county 81, agglomeration area mainly distributed in the NortheastChongqing-Sichuan Northeast, Southeast Chongqing-Northeast Guizhou, Qiandongnan area, Southeast Sichuan-Northeast of Yunnan-Guizhou Northwest, Low-Low aggregation county 125, mainly concentrated in the hinterland of the Sichuan Basin, the Chengdu Plain, the main city of Chongqing area, in the central Yunnan Basin in Kunming as the representative of Yunnan central urban agglomeration area, lack of Low-High、High-Lowcounty gathered region. Poverty county village hot spot analysis, the southwestern region of the larger hot gathering area in Northeast Sichuan-Northeast of Chongqing 、 Southeast Chongqing-Northeast of Guizhou, Southeast of Guizhou and Southeast SichuanNorthwest of Guizhou-Northeast Yunnan four regional, and in the hinterland area of Sichuan Basin, central and eastern areaof Yunnan, the formation of the city to Chengdu and Chongqing, Yunnan city group as the representative of the group of counties poor villages cold point area.(3) Southwest counties poverty village space distribution pattern of the poverty mechanism, the influence of natural and geographical factors are mainly the effects of geographical location, natural ecological environment and natural resources, the natural ecological environment factors are the most important influencing factors. The geographic and cultural factors on the influence mechanism including history, culture, economic development and public facilities.(4) Based on the geographical environment, the sustainable poverty alleviation measures mainly include three aspects: the protection of the ecological environment, economic environment and social environment.
