Study On Carrying Capacity And Sustainable Utilization Of Land Resource In Beijing

Based on the development strategy of Beijing city and the statue of land development and utilization, this study combined the evaluation of present situation and analyses of the future forecast, evaluated and analyzed the carrying capacity of the land resource in Beijing, and proposed the Sustainable using pattern of land resource. Since the fact that the problem of land resource has become a"bottleneck"to the modernization construction of Beijing, the study provides scientific theory source for establishing a steady, coordinated and sustainable relationship between population and land using.This paper based on the carrying capacity of land resource and Sustainable Utilization of study and review. The advanced theories both at home and abroad, such as Resource Scarcity Theory , Sustainable Development Theory, Regional Industrial Distribution Theory , Property Theory and World City Theory and so on, are used to evaluate and analyze the land resource capability, including population capability, ecology capability, construction scale capability, ecology capability, comprehensive capability and the model of the sustainable utilization. Both quantitative and qualitative evaluating methods are employed, and the former is major.On the basis of analysis and research of the development status of Beijing City and land development and utilization, establishing the carrying capacity of land resources integrated evaluation index system, respectively evaluate the land resource population capability, ecology capability, construction scale capability, ecology capability. In the population capability evaluation part, the average per land area and food demand is adopted to evaluate the present situation of construction land and farmland capability in Beijing. Per capita index method used to evaluate the urban construction land population capability in the sub-region. The conclusion is that the existing population scale has exceeded the reasonable capability of the core area of the capital function, and there is some construction potentiality in functional development district. Land carrying capacity in the evaluation of the rural population, 400kg per capita share of grain for the evaluation criteria, the carrying capacity of land resources has been basically to meet the food needs of agricultural population in Beijing, and a small part of the urban population. According to the ecological suitability assessment of the amount calculated in Beijing, the amount of land for construction is small surplus. There is great construction potentiality in urban construction land resources. Because of the deficiency of natural condition and the city development policy, the land economic carrying capacity of Beijing has fallen behind the level of some development international cities. Comprehensive evaluation of each single capacity, the study used "decision-making analysis of variance were", obtained the overall carrying capacity of land resources in Beijing which is middle powerful. Through analysis the utilization of Land Resources in Beijing, the study put forward sustainable using of land resources and a series of suggestion to realize the strategy model of Sustainable using of land resources.
