| 摘 要： | 基于辽宁省25个气象测站1984~2013年6~8月的逐日平均气温、平均风速、相对湿度以及日照时数等数据,以温湿指数、风效指数及着衣指数综合加权法与旋转经验正交函数分解法（REOF）相结合,分析辽宁省夏季舒适程度,并对舒适度变化趋势进行舒适区域划分。结果表明：① 温湿指数、风效指数及着衣指数均呈现出6月指数最低,7月指数相对较高的特点,年际变化特征不明显,且3个指数各个月空间分布上呈现的趋势并不相同。② 6月全省均处于“舒适”等级,而7月和8月处于“比较舒适”等级,说明6月是辽宁省夏季旅游最佳月份。6月和7月在空间分布中呈现出由西北向东南递增的趋势,但8月却呈现出相反的趋势。③ 根据旋转经验正交函数分解方法对前3个载荷向量旋转后的结果,将辽宁省划分为3个舒适区域,分别为辽宁中部及西北部区域、辽宁东部区域和辽东半岛区域。 |

| Abstract: | Based on the 25 weather stations data in Liaoning Province in summer (June, July and August): average temperature, average wind speed, relative humidity and sunshine duration between 1984-2013 and combined with THI, K, and ICL and revolving experience orthogonal fashion (REOF) to divide Liaoning Province into different parts by comfort level of climate and analyze change tendency. Results indicated that: 1) THI, K and ICL both showed characteristic of the lowest index in June and relatively high in July , intrannual variability is not obvious, and the trend of spatial distribution of each month’s three indices is not the same; 2) The "comfortable" level is in June, while July and August are “less comfortable” level. So it indicate that June is the best month of summer tourism in Liaoning Province. June and July showed the spatial distribution increasing from nort hwest to southeast trend, but in August preached the opposite trend; 3) According to the first three REOF results, Liaoning Province will be divided into 3 comfort zones, the three zones are the central and northwestern regions of Liaoning, the eastern region of Liaoning, and the Liaodong Peninsula region. |
| Keywords: | Liaoning Province summer comprehensive index of comfort REOF climatic regionalization |
