摘　　要：利用甘肃省37个气象台站的气候资料,采用温湿指数、风寒指数、着衣指数及综合舒适度指数等气候舒适度指标和反距离权重空间插值分析方法,对甘肃省气候舒适度的时空分异特征进行了详细分析,研究表明,4—10月气候舒适度都比较优越,6—8月气候舒适度最佳,1月、12月气候舒适度较差。气候舒适度整体呈纬度地带性变化,由东南向西北递减,同时垂直地带性影响显著,导致海拔较高的南部和中部地区气候舒适度较差,其中陇南市、天水市和白银市气候舒适度最好,其次为平凉市、庆阳市等地区,比较差的有甘南藏族自治州、张掖市和金昌市等地区。研究结果全面反映了甘肃省气候舒适度的时空分异规律,对于研究区旅游规划、人口分布研究等有一定参考价值。In this paper,temperature-humidity index,wind-chill index,clothing index,the comprehensive index of climate comfort,and inverse distance weighted spatial interpolation analysis are used to analyze spatiotemporal variation of the climate comfort based on the climatic data from thirty-seven weather stations in Gansu province. The results show that the climate comfort from April to September is better,and the best period appears from May to August. But the climate comfort in January and December are relatively bad. The climate comfort is gradually decrease from southeast to northwest as latitudinal zonality. Furthermore,vertical zonality of the climate comfort causes climate comfort in the south and central part region with higher altitude on the province is worse and climate comfort in the cities of Longnan,Tianshui and Baiyin is better. Then following the listed cities,such as Pingliang,Qinyang,and etc. But the climate comfort in the areas of Tibetan Autonomous Prefecture,Zhangye,and Jinchang are relatively poor. The results of this paper reflect spatiotemporal variation of climate comfort in Gansu province,and have contain certain reference value for the tourism planning,the research of population distribution,and etc.
