摘要
为了推进城市紧凑发展、提高城市内部和边缘地区的土地利用效率,优化城市空间形态,文中应用GIS空间分析法、生态足迹法和用地适宜性评价法,选取典型的绿洲工业城市嘉峪关市为研究对象,探索划定了嘉峪关市城市开发边界。结果表明:嘉峪关市2030年刚性城市开发边界为249.92 km^2,2020年和2030年弹性城市开发边界分别为106.78 km^2和149.35 km^2。GIS空间分析法、生态足迹法和用地适宜性评价法能够满足未来城市开发边界划定的技术方法要求。
In order to control the urban sprawl and promote the compact development of the city,and to improve the efficiency of land use within the city and its peripheries,the GIS spatial analysis,ecological foot printing and land suitability evaluation were applied in this paper to delimit the urban development boundaries of Jiayuguan city to optimize the shape of the urban space. The results showed that the rigid urban development boundary of Jiayuguan city is 249. 92 km^2 in 2030,and the flexible urban development boundary is 106. 78 km^2 and 149. 35 km^2 in 2020 and 2030 respectively.What＇s more,the method of GIS spatial analysis,ecological foot printing and land suitability evaluation can meet the technical requirements for delimiting the urban development boundaries in the future.
