城市增长边界划定方法研究——以西咸新区为例
|
摘要
城市增长边界的划定可以有效地控制城市发展规模,缓解人地矛盾.本研究对城市增长边界的划定方法按正反规划和定性定量两种思路进行了分类,并以西咸新区为例,结合GIS技术,首先从反向思路出发,确定刚性指标因素因子,明确不宜建设区,从而划定研究区的刚性增长边界;再从正向思路出发,预测2020年和2030年研究区城镇人口和城镇用地规模,结合其土地建设适宜性评价和空间扩展结构,分别划定2020年和2030年的弹性增长边界;将刚性和弹性边界划定结果相叠加,得到西咸新区最终城市增长边界.
The demarcation of urban growth boundary can effectively control the development scale of cities and alleviate the conflict between population and land resources. In the paper, the demarcation method of urban growth boundary has been classified as two planning ways: the combination of pros and cons approach and the combination of qualitative and quantitative method. Taking Xixian New District as an example, with GIS technology, the rigid index factor has been chosen, the unsuitable construction area and delimits nonflexible boundaries of Xixian New District have been made clear from negative thinking. Then from positive thinking, based on the evaluation of land suitability to construction, urban population and urban land scale in 2020 and 2030 of Xixian New District have been studied, taking into account the spatial expansion structure of Xixian New District, and the flexible boundaries of Xixian New District in 2020 and 2030 have been delimited. Finally, the paper superimpose the results of nonflexible and flexible boundaries in order to ascertain the final boundaries.
