Rural Residential Consolidation Mode Selection Research Based On Location Conditions In Poyang County

In land consolidation, rural residential land consolidation is important, and also the result of future urban and rural development and new rural construction, because of the important role of optimization of the rural residents layout and to achieve the balance of arable land, it becomes the key of the land consolidation. The rural residential consolidation mode select studying, provides an important theoretical basis and guidance for the village planning. In order to guarantee sustainable development of agriculture, effectively protecting cultivated land, we must implement the effective measures, and limit residential construction continuing extensive expansion, combined with constraint guidance of town planning, residential land consolidation is a favorable way to protect cultivated land.Based on the study of domestic and foreign theory and practice, in this paper, taking Jiangxi Province Poyang County as an example, through the literature review method to summarize and analysis the theory of rural residential land consolidation, through investigation, with the help of GIS spatial statistical analysis tools, study and analysis the present situation of rural residents and the existing problems in Poyang County, and on this basis, evaluate the rural residential location conditions, and select the mode for rural residential land consolidation in the area.Studying on the rural residential land consolidation mode of Poyang county, the results are obtained as follows:(1)Summarize the main features of land use in Poyang County, the quality of the cultivated land gradually decreased, farmland infrastructure backward; The disasters are frequent surround Poyang Lake region, the structure of land use is unstable; The land reserve resources are short and the development potentiality is small.(2)By using Voronoi diagram of Cv value method, nearest distance method, the dispersion index method to analysis the spatial distribution characteristics of rural residents in Poyang County, the results showed that: most of the township of Poyang County rural residents show cluster distribution, and also a little less part of the township rural residents is distributed relatively decentralized.(3)Analysis each location influence factors of rural residents in Poyang County, construct the location evaluation index system of rural residents, evaluate the location conditions of 7406 rural residential patches, divided to 5 grades. Overall, residents location in the South are superior than those in the North, with the decline of location evaluation grade, the number and area of rural residential patches decrease gradually. Grade 1 area is the largest, which is 6125.40hm2, accounting for 29.16% of the total area of residential; grade 2 residential patch number is the most, which is 1870, accounting for 25.25% of the total residential patches; grade 5 residential patch number and area are the minimum, which proportion are only 13.23% and 7.18% respectively.(4)Based on the results of rural residential patches evaluation, using the area weighted method to summary to each administrative village, and divided 529 administrative villages in Poyang County into 5 grades. Overall, the southern location grade is superior than that in northern, the southern and central west north of the administrative villages are in grade 1, and the more remote northern administrative villages are in grade 5. Each grade area reduces gradually from high to low, grade 1 area is the biggest, which is 90203.95hm2, accounting for 25.77% of the total evaluation area, grade 5 area is the minimum, the proportion is 13.54%. From the number of administrative villages, with the grade decline, the number of administrative village also gradually reduce, grade 1 number of administrative villages is the most, which is 176, accounting for 33.27% of the total number of administrative villages, grade 5 administrative villages is the least, which is only 26, and the proportion is only 4.91%.(5)From the village development, organization and management, financing three aspects summarizes our country’s rural residential land consolidation mode. On the basis of location evaluation results, combined with actual situation of Poyang County, divided the consolidation mode of rural residential into five, respectively: urbanization development mode, reform development mode, internal potential mode, migration village and point mode, overall migration mode. Among them, the urbanization development mode mainly includes the administrative villages near the county or township, and involving 92 administrative villages in 18 townships; reform development mode and internal potential mode are applicated with the widest range, almost involving all villages and towns; while the overall migration mode in light of the administrative village at the more remote or mountainous areas which location conditions is poor, the total number is 61.
