基于熵值法的洛阳旅游气候舒适度研究

Study on Luoyang Tourism Climate Comfort Based on Entropy Method

利用1981—2010年洛阳月平均气温、月平均相对湿度和月平均风速等气候要素资料,在选取温湿指数、风寒指数和穿衣指数等旅游气候舒适度评价指标的基础上,基于熵值法构建洛阳综合旅游气候舒适度指数,分析洛阳旅游气候舒适度,确定舒适、较舒适、较不舒适、不舒适旅游月份。结果表明:将熵值法应用于洛阳综合旅游气候舒适度指数评价指标权重,体现了以样本数据为基础,避免了运用层次分析法等产生的主观随意性,能更客观地反映各月气候舒适程度。洛阳气候舒适度年内变化呈M形,舒适月是4—5月、9—10月,较舒适月是6、8月,较不舒适月是2—3月、7月和11—12月,不舒适月是1月。

Based the meteorological data in Luoyang during the period from 1981 to 2010,the main tourism climatic factors,such as temperature,relative humidity and wind speed were analyzed. After calculating and analyzing the temperature humidity index,wind-chill index and clothing index,Luoyang integrated tourism climate comfortable index（ short for Luoyang index） was established based on entropy method. According to Luoyang index,the climate environment of Luoyang was evaluated. The results were as follows： entropy method,using sample data as the basis to determine the weight coefficients of evaluation indexes of Luoyang index,avoided the subjective randomness by using analytic hierarchy process. It could objectively reflect the climate comfort degree of each month.It indicated that Luoyang climate comfort degree change during the year was M-type,the comfortable months were from April to May,and from September to October,the more comfortable months were from June to August,and the less comfortable months were from February to March,July,and November to December,the uncomfortable month was January.
