基于GIS的楚雄市主城区开敞空间布局优化研究

Research on the Optimization of Open Space Layout in the Main Urban Area of Chuxiong City Based on GIS

摘要: 开敞空间作为与城市实体建筑空间相对应的灰空间，提供了人们应急避难的场所，关系到一个城市的发展。本文研究基于卫星影像图，利用GIS空间分析技术，开展了楚雄市主城区开敞空间的空间分布研究，得出如下结论：楚雄市主城区开敞空间分布不均匀，中部分布密集，西北部、东南部较薄弱；从开敞空间的类型来看，研究区以城市学校开敞空间为主；从级别来看，以小型开敞空间为主；部分区域未覆盖到，存在服务盲区。最后针对存在问题提出建议，为优化研究区开敞空间做参考。

Abstract: As the gray space corresponding to the urban physical building space, open space provides people with a place for emergency refuge, which is related to the development of a city. Based on satellite images and GIS spatial analysis technology, this paper studies the spatial distribution of open space in the main urban area of Chuxiong City, and draws the following conclusions: the open space in the main urban area of Chuxiong City is unevenly distributed, densely distributed in the middle, and weak in the northwest and Southeast; From the type of open space, the study area is mainly urban school open space; From the perspective of level, it is mainly small open space; Some areas are not covered, and there are service blind areas. Finally, some suggestions are put forward to optimize the open space of the study area.
