摘　　要：城市化对城市气候和环境产生了负面影响,从城市气候角度进行可持续城市规划是城市规划者和决策者关注的热点问题。已有很多城市使用气候图法将城市气候信息纳入城市规划中,但这些研究集中于发达城市,对喀斯特山地城市的相关研究较少。以喀斯特山地城市贵阳市为例,在城市气候图编制的基础上,分别增加了引起喀斯特城市“异常热岛”和影响山地城市通风潜力的评估因子,采用空间自相关理论中的半方差函数确定空间气候分析单元,运用熵权法计算评估因子的权重。这些改进方法更加客观和精准地反映城市气候环境。最后,通过GIS空间分析得到贵阳市环境气候分区图,提供了缓解和改善气候条件的措施,为可持续气候空间规划发展提供建议。Urbanization has already generated a negative impact on the urban climate and environment.How to develop sustainable urban plans from the perspective of urban climate has become a hot issue for urban planners and policymakers.A large number of cities have incorporated urban climate information into urban planning and construction through urban climagram.However,most research focuses on developed cities,but few are they involved in Karst mountain cities.In the paper,the karst mountain city Guiyang is taken as an instance,the assessment factors that cause“abnormal heat islands”in karst mountain cities and those that affect the ventilation potential of mountain cities are added on the basis of the existing urban climate maps.The semi-variance function in spatial autocorrelation theory is used to determine the spatial climate analysis unit in order to fully consider the impact of different urban morphological characteristics on the urban climate.The weights of the assessment factorsare calculated using the entropy weight method.Those reflect the urban climatic environment more objectively and accurately.Finally,the GIS spatial analysis is based on to obtain the environmental climate zoning map of Guiyang,which is conducive to providing measures for improving the climate conditions and scientific advices for the sustainable climate spatial planning and development of Guiyang.
