摘要
选取1971—2020年洛阳市的9个气象站点的月数据,分别对50年间的舒适度指数进行统计分析和空间可视化,从时空演变的角度对洛阳市旅游气候的舒适度实现精细化评估。结果表明,各舒适度指数的舒适月集中分布于4—5月和9—10月,在50年间,温湿指数逐年上升,着衣指数逐年下降,风效指数和综合舒适度指数在春、秋和冬季逐年上升,夏季呈平稳波动下降趋势。在空间分布上,温湿指数为东北高、西南低的空间格局,风效指数呈西南部和东北部低,东南部至西北部高的带状分布趋势,着衣指数为东北低、西南高的空间格局。综合舒适度最佳时间为4月和10月,主要分布于洛阳市东北部区域;5月和9月舒适度较好,以西南部的栾川和东北区域为主。洛阳市的气候趋于暖湿化,舒适度在50年间呈波动上升趋势。
The monthly data of 9 meteorological stations in Luoyang from 1971 to 2020 were selected to carry out statistical analysis and spatial visualization of the comfort index in the past 50 years.From the perspective of temporal and spatial evolution,the comfort degree of Luoyang′s tourist climate was carefully evaluated.The results showed that the comfort months of each comfort index were concentrated in April to May and September to October.In the past 50 years,the temperature and humidity index increased year by year,the clothing index decreased year by year,the wind efficiency index and the comprehensive comfort index increased year by year in spring,autumn and winter,and showed a steady fluctuation and decreasing trend in summer.In terms of spatial distribution,the temperature and humidity index was high in the northeast and low in the southwest,the wind efficiency index was low in the southwest and northeast,and high in the southeast and northwest,and the clothing index was low in the northeast and high in the southwest.The best time of comprehensive comfort was in April and October,which mainly distributed in the northeast area of Luoyang;the comfort level was good in May and September,and Luanchuan in the west and south and Northeast China are the main areas.The climate of Luoyang tended to be warm and humid,and the comfort level showed a fluctuating rising trend in the past 50 years.
