四川雅安碧峰峡避暑旅游气候适宜性分析

Analysis of the climate comfort for summer tourism in Bifeng Gorge,Yaan city of Sichuan province

基于碧峰峡景区逐日气温、降水、风速、相对湿度、负氧离子浓度观测资料和距离碧峰峡最近的雅安气象观测站逐日日照观测资料,利用温湿指数(I)、风效指数(K)、人体舒适度指数(HBCI)、空气清新度(负氧离子浓度N),构建旅游气象综合指数(TMCI),分析了碧峰峡景区旅游气候资源主要组成要素和各项旅游指数的月季分布特征,探讨了极端天气和气象地质灾害对碧峰峡景区避暑旅游的影响。结果表明:碧峰峡景区夏季气温、降水、湿度、风速、日照和紫外线强度等气象要素均适宜避暑旅游;碧峰峡景区5—9月的温湿指数、风效指数和人体舒适度指数、旅游气象综合指数均适宜或非常适宜避暑旅游;碧峰峡景区空气清新,全年92.4%的时间负氧离子浓度等级在I级以上,非常适合旅游;碧峰峡全年极端天气和气象地质灾害危险不大,自然灾害对碧峰峡避暑旅游的影响较小。总体而言,碧峰峡非常适宜避暑旅游。

Based on the daily temperature,precipitation,wind speed,relative humidity,and negative oxygen ion concentration observation data in Bifeng Gorge scenic area(BGSA)and the daily sunshine observation data of Yaan meteorological observatory station closest to BGSA,this paper constructed a tourism meteorological comprehensive index(TMCI)using temperature-humidity index(I),wind efficiency index(K),human body comfort index(HBCI),and air freshness index(negative oxygen ion concentration,N).The monthly and seasonal characteristics of the main tourism climate resources and tourism indices in BGSA were explored.The impacts of extreme weather and meteorological geological disasters on summer tourism in BGSA were also analyzed.The results show that the meteorological elements such as temperature,precipitation,humidity,wind speed,sunshine,and ultraviolet intensity in BGSA are suitable for summer tourism.The temperature-humidity index,wind efficiency index,HBCI,and TMCI from May to September in BGSA are suitable or very suitable for summer tourism.The negative oxygen ion concentration level in BGSA is above level I for 92.4%of the year,making it very suitable for tourism.The risk of extreme weather and meteorological geological disasters in BGSA is not significant throughout the year,and the impact of natural disasters on BGSA summer tourism is relatively small.In conclusion,BGSA is a great place for summer tourism.
