利川市旅游气候适宜性的评价和比较
Evaluation and Comparison on Climate Suitability for Tourism in Lichuan City
中文摘要：
基于中国15座主要旅游城市1960—2016年的气象资料，采用以温湿指数、风寒指数和度假气候指数为基础的综合气候舒适度指标，计算了气候舒适度指数，界定了舒适期，并对其分布规律进行了分析。结果表明：1）利川市舒适期为4—10月，多年年均综合舒适日数为153 d，占全年总天数的42%，近60年，舒适日数呈显著增多趋势，不适日数呈减少趋势；2）综合舒适期以25°N为界，以北随纬度降低而增加，以南反之，综合舒适日数随纬度降低呈现减少趋势；3）综合舒适期随海拔高度的增加，有推迟的趋势，综合舒适日数以2500 m为界，之下随海拔高度的增加而增加，之上明显减少；4）30°N附近综合舒适期基本在4—10月，综合舒适日数基本保持在150d左右。

Abstract：
Based on the meteorological data of 15 major tourist cities in China for 1960－2016, the comprehensive climate comfort index was calculated based on the temperature humidity index (THI), wind-cold index (WCI) and holiday climate index (HCI). The comfort index was calculated, and the comfort period was defined, and its distribution law was analyzed, then, based on the remote sensing and environmental data in Lichuan for recent 5 years, the air quality rate and remote sensing ecological index (RSEI) were calculated, and the ecoenvironmental quality was analyzed. The results indicate that: 1) The comfort period in Lichuan city is between April and October. The number of comprehensive comfort days are 153 days, accounting for 42% of the total days per year. The comfort days has increased significantly during the last 60 years, and the discomfort days sre decreasing. 2) in recent 5 years, the air and water environment in Lichuan has been excellent, and the ecological environment quality has been maintained steadily and steadily. 3) Compared with the main tourist cities, the regional meteorological disasters and the ecoenvironmental quality analysis show that the climate suitability is superior for Lichuan ecotourism. 4) The latitude boundary of above mentioned comprehensive comfort period is 25°N, and decreases with latitude in north. The comfortable days decreases with latitude. 5) The comprehensive comfort period has a tendency to postpone with increase of altitude, the altitude boundary of the comfort days is 2500 meters, and increases with the increase of altitude below 2500 meters, and obviously reduced with altitude above 2500 meters . 6) The comprehensive comfort period around 30°N is basically 4－10 months, and the comfortable days are about 150 days.
