摘要
利用芦山1981~2020年气象观测及生态质量监测等资料,计算出近40年及各月人居环境气候舒适度,结合归一化植被指数(NDVI)评价其旅游气候适宜性。结果表明:4~11月为芦山县人居环境气候舒适期,负氧离子等级高;近40年气温呈增加趋势,相对湿度和风速呈减小趋势;温湿指数呈上升趋势,风效指数呈下降趋势,人居环境舒适度增加,NDVI缓慢增长;温湿指数、风效指数均与平均气温呈显著正相关,与相对湿度呈显著负相关,说明气温升高、相对湿度减少是气候舒适度增加的主要影响因素。
Based on the meteorological observation and ecological quality monitoring data of Lushan from 1981 to 2020,the climate comfort of human settlements in the past 40 years and each month was calculated,and the tourism climate suitability was evaluated com-bined with the normalized difference vegetation index(NDVI).The results showed that the climate comfortable period of living environ-ment in Lushan County is from April to November,and the negative oxygen ion level was high.In the past 40 years,the temperature showed an increasing trend,while the relative humidity and wind speed showed a decreasing trend.Temperature and humidity index showed an upward trend,wind efficiency index showed a downward trend,the comfort of living environment increased,NDVI increased slowly.The temperature and humidity index and wind efficiency index were positively correlated with the average temperature,and negat-ively correlated with the relative humidity,indicating that the increase of temperature and the decrease of relative humidity are the main factors affecting the increase of climate comfort.
