| The layout of rural settlement status of the farmers stay spontaneous choice in a long time because of history、natural factors、customs and other reasons. Rapid urbanization area scattered rural residential layout,which lack of management of the state not only take up valuable land resources,but also hindered the development of regional economy to a certain extent,hindered the construction of new countryside. To improve their use of extensive land Situation,How rural residential layout optimization become an important part of scientific research. In recent years,rural land remediation work carried out throughout the supply and demand of land for construction has become increasingly evident. With the implementation of "change link" and other policies and choose the appropriate type of regulation for different types of rural settlements,it has become one of the important directions for future remediation work. In this study,we are deepening temporal Rural Residency and renovation planning theory system hilly areas to promote "urban-rural integration" and new rural construction is important. At the same time, the study of the future of rural construction land intensive use of certain reference,is conducive to promoting the process of urbanization,to further improve production and living conditions in rural areas,promote urban and rural development.Beibei District of Chongqing Municipality is the era of the outer ring and the two rivers important built-up areas,the rational use of its rural settlement not directly affect regional economic development. Beibei belongs to the Southwest Pass fold belt, Huaying Mountain barrier type anticlinorium broom arcuate structural zone Chongqing arc part of the territory of the trough of low mountains, the foothills of bare hills, valleys and along the shallow hill constituted the highest elevation of 1312 m, the lowest 175 m. It is typical of hilly areas. Beibei Districtis typical of the hilly area, the rural residential layout optimization for residential renovation Optimization of Chongqing,which has the strong representation. Beibei District Rural Settlement evolution and optimization of layout optimized for other settlements in hilly areas to provide further information. For example Beibei Districtin 2009 and 2014 based on data from the land use change data.In this paper, the use of GIS technology,landscape pattern analysis,Voronoi diagram Cv value factors and temporal variation on rural residential area was hilly layout analysis. By determining the rural settlement location suitability,which is divided into different types of remediation,and finally make the appropriate optimization measures for different types of remediation,provide a theoretical basis for future remediation work. Here are the main contents and conclusions of this dissertation:(1) The number of plaques and rural residential area of Beibei District has decreased, the average plaque area remained stable, plaque area index variation has a slight decline. The region’s settlements are mostly located in flat terrain from residential distribution,which away from the roads, water and close to the downtown area. Terrain index of 3 or less,less than 800 meters away from the road,away from the water within 1,000 meters,less than 2500 meters from the city center on rural settlements distribution greater impact.(2) The improvement of rural settlements into bag-in mode,gathering type, controlled,moved disposable based on the quantitative analysis of rural residential layout, through multi-factor comprehensive evaluation method,Based on urban land to attract the threshold of the village,such as the transformation of priority rural residential near the center of town east village Xiema town,the satellite village,village lighthouse Tsai Kong, Shuang bei village; residential area based on frequency histograms and population, disaster, economic development and other relevant information,the scope of development come to gather Beibei District will be identified as key development areas of the region; for scenic sites, such as Jinyun, partial rock town, Jindaoxia scenic settlements, to classify as controlled development; based on the distance to the center of town,population,residential area and other factors, will be distributed in remote areas and harsh conditions unsuitable for residential areas is determined to move the disposable type residential land development.(3) This dissertation proposes a distribution optimizing scheme and consolidation recommendation son rural settlement,base on GIS pre-judgement,which can provide ascientific basis for the rural construction of land consolidation and new rural communities construction. This section proposes different types of regulation types corresponding layout optimization. Delineation of the scope of the center of the village by the attractive village center evaluation method, used in the preparation of disposable move, merge type of rural residential migration direction. Finally,the use of maps show Beibei the whole area and a representative of the township optimization results provide a reference for future remediation work. |
