摘要
城市发展规模与发展水平离不开城市的地质基础条件。因此,城市地质环境承载力分析是城市发展与规划必需的基础工作。在分析了昆明盆地的地质基础条件之后,从正负两面阐述了影响昆明城市发展的主要地质环境条件,并对其影响程度进行了分析。在此基础上,采用GIS的空间叠置技术,对昆明市市域区和规划区新建、扩建区域进行了地质环境承载力的分级。本区域共分为三级:第一级为适宜建设区,第二级为适度控制建设区,第三级为中度控制建设区。同时认为,从地质环境条件来看,昆明盆地内没有严格控制建设的区域。该研究为昆明城市的发展与规划提供了很好的参考。
The development scale and level of an urban area relies on its geological factors. Hence, study on urban geoenvironment load capacity is necessary for urban development and planning. After study on its basic geological situation, the positive and negative geological factors affecting urban development of Kunming were pointed out. And their affecting degrees were also examined. Afterwards, for ranking urban geoenvironment load capacity of different areas, GIS software was used to overlay dif ferent geological factors layers. And the urban and planning areas are ranked to 3 levels, the best level area is suitable for building, the secondary area is moderatcly suitable for building . and the third area is not suitable for building unless more safety protects are available. And from the geoenvironment point of view. there is no area under strict control for urban building in the Kunming Basin. This study can offer good reference for the urban development and planning of Kunming City.
