Strategy Research for Urban Land Reserve System under Rapid Urbanization--A Case Study on Longgang, Shenzhen
快速城市化背景下的城市土地储备策略研究——以深圳市龙岗区为例

With rapid urbanization,land reserve system has become an important means for ratio-nal land use and land optimized configuration.It has been put into practice in many cities. However,there are two basic problems in the process of putting the system into effect.One of which is capital oriented,i.e.the area and location of land reserve is usually determined and/or disturbed by capital requirement of the municipal government.The other is investment required,i.e.the area and location of land reserve is usually determined and/or distributed by the invest-ment required from the investors.Obviously,the two kinds of problems are prone to bring the gap between long-term urban planning and short-time capital shortage in urban construction.In view of the successful experiences of advanced countries and regions in urban land reserve system,a rational urban land reserve and supply plan is the key to the urban land reserve system.It is propitious for urban land reserve system to the transformation of capital oriented into function oriented and investment required into planning introductory.Using Longgang district,Shenzhen city as a case,urban land reserve plan is studied from three connected steps in the present paper.First of all,the amount of the construction land requirement in the near future is predicted using econometric and urban expansion model.Subsequently,the potential reservable land is evaluated by GIS techniques based on the establishment of the evaluating indices of potential urban land reserve.Finally,the executive short-term land reserving plan and mid-term developing land reserving plan are set down.
