摘　　要：气候舒适度持续时间的长短,是影响旅游地旅游季节长短及旅游地开发的重要因素.利用了华东地区132个气象站点30年的月均气温、月均相对湿度、月均日照和风速等气候要素数据,利用ArcGIS平台,基于克里格和协同克里格插值方法,计算温湿指数和风效指数,获得华东地区栅格单元为1 km的气候舒适度评价图,并对其空间分布规律及各月份气候的舒适性进行了分析.结果表明:(1)我国华东地区温湿指数与风效指数的总体分布趋势是随纬度及海拔高度由南向北、由低到高而递减.风效指数的舒适区比温湿指数的偏大;(2)华东地区的旅游气候舒适期,地域差异显著,最高值分布在福建.气候舒适期为5个月的区域最大,占华东地区总面积的62.7%.舒适期在3个月的地区最少,占华东地区面积的比例不足1%.The duration time of climate comfort level is an important factor that influence the length of tourism season and development of tourism destination.This paper used the monthly average climatological data of 30 years from 96 whether station in East China,calculated THI and K based on software interpolation technology,got the climate comfort charts of East China at a 1km×1km grid size,furthermore analyzed the spatial distribution regularities and comfortableness of each month.Results show that THI and K of East China decrease gradually from south to north,from low altitude to high altitude.The annual period of comfortable climate is longer when analyzed in terms of K rather than THI.The tourism climate comfortable period of East China shows significant regional difference,the maximum value distributed around Fujian province.The predominant length of climate comfortable period in China is five months per year which covering 62.7% of the total area,while areas that have climate comfortable period for 3 months are most limited,covering less than 1 % of East China.
