哀牢山北段东侧人居生活环境气候适宜度分析

Analysis on the Climate Suitability of Human Living Environment in the East of Aailao Mountain

为科学客观评价哀牢山北段东侧(南华、楚雄、双柏)人居生活环境的气候适宜度,基于云南省126个县的气温、降水、日照时数、风等12个气象影响因子,用主成分分析法分析了各地的人居生活环境气候影响评价指数。统计了牢山北段东侧与中国气候之都“浙江丽水,贵州六盘水、贵阳,四川雅安,重庆城口”和云南知名旅游生活居住地(丽江、大理、昆明)的气温、降水、湿度、日照等极端气象影响值,并分别计算了各地的温湿指数、风效指数、人体生理舒适度。分析结果表明:哀牢山北段东侧人居生活气候适宜度指数与大理、丽江相等,略高于昆明及周边;极端气象影响和人体生理舒适度指数介于5个气候之都和昆明、大理、丽江之间。

In order to scientifically and objectively evaluate the climate suitability of the living environment of the eastern side of ailao Mountain (Nanhua, Chuxiong and Shuangbai), based on 12 meteorological influencing factors such as temperature, precipitation, sunshine hours and wind in 126 counties of Yunnan Province, Principal component analysis (PCA) was used to analyze the evaluation index of human living environment and climate impact. The influence values of temperature, precipitation, humidity, sunshine and other extreme meteorological events on the east side of the northern part of the Langshan Mountain, China’s climate capitals “Lishui in Zhejiang Province, Lipanshui in Gui-zhou Province, Guiyang in Guizhou Province, Ya’an in Sichuan Province, and Chengkou in Chongqing” and famous tourist living places in Yunnan Province (Lijiang, Dali, and Kunming) were calculated. The temperature and humidity index, wind efficiency index and human physiological comfort were calculated respectively. The results show that the living-climate suitability index of the eastern part of Ailao Mountain is equal to that of Dali and Lijiang, and slightly higher than that of Kunming and its surrounding areas;the influence of extreme weather and the index of human physiological comfort are between 5 climate capitals and Kunming, Dali and Lijiang.
