Study On Spatial Layout Of Urban And Rural Land

At present, China's national condition is densely populated and serious shortage of land reserve. Along with the further development of economic and social ,and rapidly increasing level of urbanization, the contradiction between people and land has become increasingly conspicuous. For the questions arising in the course of landuse,for example, each construction occurred a large number of high-quality arable land, the low efficiency of land use, the structural imbalances of land use and other irrational land use,so it is effective to ease the contradiction between people and land and to protect national economic development that forecasting scientific and reasonable land use demand, allocating optimally land resources, Structure and layout of urban and rural land use is one of the important elements in land use planning. In the background that broadcasting a new round in the current National Land Use Planning, optimizing the layout is both strategic choice of mitigating urban and rural land use land conflicts and improving the efficiency of land utilization,and an important way to promote land conservation, and also essential end result of urban and rural development.The thesis is based on urban and rural land-use space layout optimization. First ,make sure the target of urban and rural land-use space layout, through lulong situation analysis, point out the urban and rural land-use problems. On this basis, take the contradiction between the cultivated land protection and economic development as the starting point, trying to build urban land space layout optimization theory method in hebei province, and take Lulong County as an example . Main conclusions are as follows:1)Through the comprehensive metheods such as the regression analysis, GM (1,1)grey models, the quota and so on, it forecasts the need of urban and rural areas and on the basis of the linear optimize the use of models. It gets the results of the number of urban and rural structure in 2020 by optimizeing:town with an area of rural 954.08 hm2;settlement land area is 8808.82 hm2;residential quarters and industrial and mining land area is 1034.21 hm2:the transport land area is 832.71 hm2;the area for water space 958.38 hm2;other construction land area is 118.78 hm2. It provids a basis reference for the construction sites Lulong county scientific,reasonable indicators for the use of urban and rural areas.2)By applying the evaluation method of combination the suitability for the arable land and consruction land on urban and rural areas,it takes Lulong country as an empirical research and gets the results:First level for 3735.34 hm2 ;the second area of land for 17277.17 hm2 ;The third levels of the 41512.51 hm2 ;The fourth levels of 24205.78 hm2 ;The fivth categories for 8840.63 hm2.According to arrangements for land with the results of evaluations, the way of land use conflict between cultivated land protection and economic development can be solved.It also provides good theoretical basis and technical support for construction rational development..3)By using geographic information systems(gis)for platform,according to urban and rural land evaluation,follow the priority of land occupied by way of high-grade, the number of urban and rural land use structure optimization will result in the space layout.By using Lulong County in order for empirical study,get spatial structure and layout are Lulong County. The results show that: urban and rural land distribution is more concentrated, small area of scattered rural settlements and a significant reduction in industrial land, traffic land and water distribution sites in the current situation to be extended, other sites concentrated in tourism planning within the project area.Making urban and rural areas to Lulong county more optimized space layout, and effective avoidance of the high suitability of the land cultivated, occupied land for construction of priority of land suitable for high, achieve land protection and economic development win-win, protected the sustainable use of land resources of Lulong County.And for protected rural and urban land use structure optimization results of the implementation, relevant policy recommendations put forward.
