Research On Rural Residential Land Consolidation Based On Spatial Interaction In Wuan

Rural residential areas are a major place for peasant settlements andConfiguration of survival data. with the new rural construction of "productiondevelopment, life well-off, local custom civilization, village neatly, managementdemocracy", scientific and rational layout of the rural residential areas can not onlyincrease the efficiency of the intensive land use, ease the sharp contradiction betweencultivated land and construction land in our country, it can improve rural livingenvironment and farmers’ quality of life as well. A new round of land reclamationplanning revision is in process, as the core content of rural construction landremediation, rural residential areas is an important way to realize the integration ofurban and rural areas.Based on the geographic information system technology, this paper which takingthe WuAn in Hebei province as a case, applied spatial interaction theory into ruralsettlement space structure analysis, and then determine the rural residential spatialstructure optimization type. It will provide a reference for the rural residential areas inWu An. The main contents and conclusions are as follows:（1） Through the common words matrix and visualization analysis in spatialinteraction theory, it was kept a view of the current research hot spot of spatialinteraction. Meanwhile, it is essential to revise the gravity model to make them moreappropriate for residential spatial structure analysis;（2） In the aspect of rural residential areas, and per capita of rural residentialland scale, to summarize quantity characteristics of WuAn rural settlement; And in theaspect of the central tendency and distribution direction deviate, to describe economicand geometry spatial characteristics of rural residential areas;（3）The index system of quality concluded19indicators in the pact ofdevelopment foundation, production conditions and living environment. Through theprincipal component analysis algorithm, it extracted principal component index toconstitute the new quality factor, and the principal components variance contributionrate was used to determine the quality factor weight, finally draw a "comprehensive quality". The time distance took the place of traditional spatial distance. Based on allof the above, it is well to measure the gravity value between the rural residential areaand town. On one hand, through clustering gravity value between rural residentialareas and recently urban, to determine the urbanization rural settlements; On the otherhand, summarizing all gravity value acting on rural residential areas, which namedpotential value, to determine the type of residential space structure adjustment usingclustering analysis.In summary, as an important theory in geography and regional economics, thespatial interaction is able to analysis rural residential land use spatial structure, and thegravity model and potential model can be used to simulate the connection between therelevant factors in rural residential land, it broaden the application of the spatialinteraction theory.
