摘要
选取1971—2020年山西省忻州市15个国家气象站逐日观测资料,根据人居环境气候舒适度评价标准,应用线性倾向率、滑动平均、Mann-Kendall突变检验等方法分析忻州市人居环境气候舒适度变化特征。结果表明:忻州市整体的人居环境气候舒适度为寒冷,6—8月为舒适月,7月为最舒适月,年舒适日数为102.2 d。1971—2020年忻州市风效指数和温湿指数均呈显著的上升趋势,分别于1986年和1997年突变增大,人居环境舒适度提升;忻州市人居环境气候舒适度随海拔升高而降低,舒适日数随海拔升高而减少。5月底至9月上旬五台山风景区舒适度较好,7月舒适度最好。整体上,忻州市人居环境气候舒适区和较舒适区位于海拔较低的忻定盆地和黄河沿岸,舒适度较差区为高寒山区。
This study selects daily observational data from 15 national meteorological stations in Xinzhou city of Shanxi province from 1971 to 2020.Using methods such as the linear trend rate,moving average,and Mann-Kendall sudden change test,it analyzes the characteristics of changes in the climate comfort of residential environments in Xinzhou city.The results indicate that the overall climate comfort of the residential environment in Xinzhou city is cold,with June to August being the comfortable months and July being the most comfortable month,totaling 102.2 comfortable days per year.From 1971 to 2020,both the wind efficiency index and the temperature-humidity index in Xinzhou city showed significant upward trends,with sudden increases in 1986 and 1997 respectively,enhancing the residential environmental comfort.The climate comfort in Xinzhou decreases with increasing altitude,as does the number of comfortable days.The comfort level is relatively higher in the Wutai Mountain scenic area from late May to early September,with July being the most comfortable.Overall,the climate comfort zones and relatively comfortable zones in Xinzhou city are located in the lower-altitude areas of the Xinding Basin and along the Yellow River,while the less comfortable areas are in the high-altitude cold mountain regions.
