【摘要】：根据1964—2015年辽宁省23个气象站点的逐日平均气温、相对湿度及平均风速资料,采用人体舒适度指数法计算人体舒适度指数,在季尺度上分析辽宁省不同等级舒适日数演变情况及典型旅游城市最佳旅游期;运用旋转经验正交函数分解法(REOF),分析人体舒适度指数季尺度空间变化特征,并应用Arc GIS软件进行舒适区域划分。结果表明:(1)辽宁省多年平均冷不舒适日数呈降低趋势,舒适日数呈增加趋势,热不舒适日数也呈微弱增加趋势;舒适程度夏季秋季春季冬季;(2)除冬季外5座典型旅游城市均适宜旅游,夏季为最佳旅游期;其中,沈阳、本溪更适宜春季旅游,大连更适宜秋季旅游。(3)辽宁省四季舒适度变化情况可大致划分为辽西、辽中、辽东三个区域,具体划分情况随季节有相应变化,总体舒适度由辽宁东部向西部逐渐递减。
[Abstract]:Based on the daily mean air temperature, relative humidity and average wind speed data of 23 meteorological stations in Liaoning Province from 1964 to 2015, the human body comfort index was calculated by the method of human comfort index. On the seasonal scale, the evolution of comfort days of different grades in Liaoning Province and the best tourism period of typical tourist cities are analyzed. The rotation empirical orthogonal function decomposition method (REOF),) was used to analyze the spatial variation characteristics of the comfort index of the human body on a quarterly scale and the comfort region was divided by Arc GIS software. The results show that: (1) the average number of days of cold discomfort in Liaoning Province is decreasing, the number of days of comfort is increasing, and the number of days of thermal discomfort is slightly increasing, the degree of comfort is summer, autumn, spring and winter, and the number of days of comfort is increasing slightly. (2) all five typical tourist cities except in winter are suitable for tourism, and summer is the best tourist period; Among them, Shenyang and Benxi are more suitable for spring tourism and Dalian is more suitable for autumn tourism. (3) the changes of comfort degree of Liaoning Province in four seasons can be roughly divided into three regions: Western Liaoning, middle Liaoning and eastern Liaodong. The overall comfort gradually decreased from eastern Liaoning to western Liaoning.
