Study On The Optimal Allocation Of Land Resources In Hotan

Research purposes: The speed of urbanization has been accelerated, because of today’s rapid economic development. China is a country which typical of it’s population, the population is very large but available land is little, the development of the city are increasingly faced with the shortage of land resources, hinders the development of city’s economy, society and the improvement of people’s living standards. Hotan, located in the northwest arid desert region,which is short of land resources and water resources. In recent years, due to the unreasonable development and utilization of land and environmental pollution, such as excessive grazing, unreasonable irrigation, industrial land pollution and so on, intensified the contradictory of man-land. In order to solve some of the problems existing in the present situation of land use, to make land resources be fully protection and utilization, adjust and planning Hotan land resources is around the corner. Integrated ecological, social and economic benefits, combining the concrete facts of Hotan to optimal allocation land resources, so as to make the utilized land achieve it’s maximum output, and can be well adapt and protect to the local vulnerable ecological environment.Research methods: In combination with previous research method and make full analysis on optimal allocation of land resource,this study proposed to use the method of grey multiobjective dynamic programming model. Analyzing the present situation and problems of land use in Hotan, building land resource adjustment and optimization model, and to obtain land schemes by solving the model, to achieve the reasonable configuration of land resources. Reference The Hotan Land-Use Planning and the trend of future development, set up the decision variables, build three objective function and constraint equation, and using WINQSB software to solve the model, obtain the structure adjustment schemes of land use, finally by analyze the grey correlation degree to choose the land resources optimization solution of Hotan.Results: Based on the analysis of the current situation of Hotan, finding out some of the problems existing in the present situation of land use in Hotan. In order to solve the problem, this study considers the mutual coordination of economic, social and ecological benefits, optimization evaluation index system is established, finally it is concluded that the optimization solution of land use. According to optimization solution of land resources by 2020, to protect the city’s food supply, arable land in agricultural land increase 251.99 hectares; garden plot and forest land increase 97.28 hectares and 40.3 hectares, is conducive to improve the city environment of Hotan; grassland increase 57.14 hectares, provides a reliable basis for the development of animal husbandry. In recent years, the acceleration of urbanization and the population growth are rapid, urban and rural construction land in construction land increase 345.57 hectares by 2020; the traffic land increase 34.8 hectares; other construction land increase less, increase 12.96 hectares. Natural reserve sharply reduced 17427.69 hectares by 2020.Research conclusions: Overall, according to the scheme of optimization, on the one hand, the increase of agricultural land improve the ecological environment effectively; on the other hand, the increase of construction land, meeting the rapid population growth and people’s living standards improved with the increase of social demand. But it’s not unlimited increase, it should be improve the quality of construction land use overall plan during the expansion of construction land at the same time, with the least amount of land to create the biggest benefit. The reduce of nature reserve, not only can improve the land utilization, and to a certain extent, ease the contradiction between the contradictory of man-land. Analysis present situation of land use is capable of a good understanding of the problems existing in the current land use, provide a scientific basis for the future land planning. The research of the optimal allocation of regional land resources, play a certain role in improve the land use structure and comprehensive benefit of land use, is conducive to sustained use of land resources,and achieve sustainable and healthy development of the national economy.
