重庆万盛2014-2018年不同海拔旅游气候舒适度分析

Climate Comfort Analysis of Chongqing Wansheng Tourism at Different Elevations from 2014 to 2018

基于重庆万盛2014—2018年25个自动气象站的逐小时气温、相对湿度和平均风速等资料,计算出了万盛经济技术开发区不同海拔高度的修正人体舒适度指数。结果表明:万盛经开区修正人体舒适度指数随着海拔高度的增高成降低趋势,不同海拔高度下人体舒服天数不同,海拔在400~800m,人体感觉舒服的日数最多,占全年比例最大。从舒适度空间分布来看,春季和秋季是万盛经开区旅游的最佳季节,仅东南部高海拔地区处于"凉爽、凉"等级,大部分地区处于"舒服"等级;夏季万盛经开区大部地区处于"暖和"等级,但东南部高海拔地区"舒服",尤其是黑山谷景区是体感"舒服",是夏季旅游避暑纳凉最佳地区之一;冬季全区处于"凉、冷"等级。
