Abstract:
With undertaking the continuous deepening of Beijings decontamination task with extracting Beijings non-capital functions, population agglomeration and industrial development in Miyun district promote the demand growth of construction land.Taking the method of fractional step calculation, the quantity, grade division and spatial distribution characteristics of the reserved constructive land of Miyun district are assessed by using GIS spatial analysis techniques. The results show that: (1) the total reserved constructive land area is 79.99 km2, which accounting for 3.59% of total area. The reserved constructive lands mostly are distributed in southwestern and northeastern region of the district, and southwestern region is more concentrated and suitable for large-scale development. (2) Based on the development intensity of current construction land and exploring potential of reserved constructive land, the district can be divided into 4 categories,that is, high intensity-high potential (HI-HP) area, high intensity-low potential(HI-LP) area, low intensity-high potential (LI-HP) area and low intensity-low potential (LI-LP) area. HI-HP area and LI-HP area could be the main construction area in the process of urbanization and industrialization in the future. To achieve the goal of reducing construction land and enhancing ecological function in low potential area, the HI-HP area could play supportive roles in promoting the accumulation of population and industries. LI-HP area could be the second driving force of sustainable development of Miyun district, which should emphasize coordination between ecosystem stability and economic development. (3) Based on the spatial pattern of suitable construction land and the classification of “intensity-potential” of towns and villages, the centralized construction space is demarcated. The area within the space is 482.19 km2, accounting for 21.66% of the total district. This area will be an important space for the future urban development of Miyun district.
