广德市康养区气候舒适度研究

Study on Climate Comfort of Health Care Area in Guangde City

摘要: 本研究基于广德国家基本气象站1991~2020年30年整编气象数据，通过海拔高程订正模型，换算得到广德市康养区的气候数据序列。采用温湿指数(THI)和风效指数(K)作为评价模型，系统分析了广德市康养区的气温、相对湿度、风速和日照时数的时空分布特征及变化趋势，定量评价了其年、季尺度上的气候舒适度，并计算了年舒适天数。结果表明：广德康养区四季分明，气候温和，雨热同期。年均温为14.2℃，年均相对湿度为79%，年均风速3.0 m/s，年均日照时数1710.1小时。康养区年舒适天数达201天，其中“最舒适”等级天数为89天，主要分布在春季(4~5月)和秋季(9~10月)；“较舒适”等级天数为112天。研究表明，广德市康养区气候舒适度等级高，适宜持续时间长，具有发展康养旅游产业的极佳气候条件，是长三角地区理想的康养目的地。

Abstract: Based on the 30-year integrated meteorological data (1991~2020) from Guangde National Basic Meteorological Station, this study converted the climate data series of the health care area in Guangde City using an altitude correction model. Taking the Temperature-Humidity Index (THI) and Wind Effect Index (K) as evaluation models, it systematically analyzed the temporal and spatial distribution characteristics and variation trends of temperature, relative humidity, wind speed, and sunshine duration in the health care area of Guangde City, quantitatively evaluated the climate comfort at annual and seasonal scales, and calculated the annual comfortable days. The results show that the health care area in Guangde has distinct four seasons, a mild climate, and simultaneous rainfall and heat. The average annual temperature is 14.2˚C, the average annual relative humidity is 79%, the average annual wind speed is 3.0 m/s, and the average annual sunshine duration is 1710.1 hours. The annual comfortable days in the health care area reach 201, among which 89 days are at the “most comfortable” level, mainly distributed in spring (April~May) and autumn (September~October), and 112 days are at the “relatively comfortable” level. The study indicates that the health care area in Guangde City has a high level of climate comfort and a long suitable duration, possessing excellent climatic conditions for the development of the health and wellness tourism industry, and is an ideal health and wellness destination in the Yangtze River Delta region.
