环渤海地区主要海滨城市旅游气候舒适度评价

Evaluation of Tourism Climate Comfortableness of Coastal Cities in Circum-Bohai Sea Region

气候是影响人们旅游活动的重要因子。该文利用1971—2000年月平均气温、相对湿度、风速和日照资料,计算了环渤海地区主要海滨旅游城市的温湿指数、风效指数和穿衣指数,并在此基础上,构建了一个综合气候舒适度评价模型,以分析环渤海地区主要海滨城市旅游气候舒适度。结果表明:该地区旅游舒适度为春秋舒适型,最舒适月份集中在5—6月和9—10月2个时段,是旅游的黄金时期;夏季7—8月天气较热,属较舒适等级,但环渤海海滨旅游城市仍是避暑的好去处。总体来看,环渤海海滨旅游城市旅游适宜期较长,且与纬度关系密切。大连以北地区旅游适宜期基本为4—10月,大连及以南地区延长至11月。在旅游适宜期内,旅游活动会在一定程度上受到降水、大风和雾等不利因素的影响,但总体影响较小。

Climate is the main factor in tourism development.THI（temperature humidity index）、K（index of wind effect）and ICL（index of clothing）had been calculated by mean temperature,relative humidity,mean wind speed and sunshine duration during 1971 to 2000. A comprehensive comfort index had been used based on THI,K and ICL in order to analyze the tourism climate comfortableness of coastal cities in the Circum-Bohai Sea Region. The result showed that the tourism comfort degree was the spring and autumn comfortable type. The comfortable months were from May to June and September to October,which were golden period for tourism. The air temperature was high in 7-8 month.Coastal Cities in the Circum-Bohai Sea Region were still good places for summer tourism. Overall,Coastal Cities in the Circum-Bohai Sea Region had a long tourism comfortable period.The tourism comfortable period was from April to October in the north areas of Dalian,the south area of Dalian was delayed to November. In the period,the influence of precipitation,gale and dense fog on tourism were less.
