中文摘要：

借助1971～2010年河湟地区代表性站点西宁、同仁、贵德、民和的月平均气温、相对湿度、风速、日照4个主要气象要素的观测资料,计算并分析了反映旅游气候舒适度的温湿指数和风效指数的时空变化特征.结果表明：河湟地区旅游景点的旅游舒适期较短,其中西宁、贵德、同仁的旅游舒适期主要集中于6～8月,民和旅游舒适期较长,集中于5～9月.河湟较不舒适期多在3月～5月和9～11月,多达6个月.旅游不舒适期主要在最寒冷的12～1月,对旅游出行产生严重制约.河湟地区旅游舒适期分布特征使其盛夏季节旅游度假避暑功能凸显,对高原旅游业发展极为有利.

英文摘要：

based on meteorological observations data from 1971 to 2010, this paper analyzes four main meteorological factors such as monthly average temperature, relative humidity, wind speed, sunshine of regional representative, Xining, Guide, Tongren,Minhe. Spatial and temporal variations of temperature and humidity index and wind efficiency index which reflecting tourism climatic comfortableness are also cal- culated and evaluated. The results show that： The period of Hehuang tourism climatic comfortableness is shorter. Xining, Guide, Tongren focused on 6-8, Minhe has longer period vary with 5-9. Averagely, less comfortable period is up to six months, vary from 3-5 and 9-11. Travel uncomfortable period is al- ways in the coldest December, January, which seriously constrains tourism development. Distribution characteristics of Hehuang climatic comfortableness highlight its tourism attraction in summer, which is extremely favorable to the plateau tourism development.
