云阳县创建中国天然氧吧的生态环境特征分析

Analysis of Ecological and Environmental Characteristics of Yunyang's Creation of Natural Oxygen Bar in China

利用云阳县1957-2018年的气象观测资料,通过温湿指数和度假气候指数分析了云阳县的气候舒适度情况和全年的适游期情况,并分析了2018年的负氧离子含量数据、环境空气质量监测数据和水质监测数据,结果表明:春季、初夏和秋季是云阳人居环境最舒适的时期,全年人居环境气候舒适度天数在138 d;云阳县度假气候指数全年均为适宜及以上等级,适宜出游;负氧离子的年平均含量在1400个/cm^(3)以上,达到清新空气的标准;空气主要污染物含量均低于国家二级标准,且呈下降趋势;云阳县地表水质质量常年保持在Ⅱ类水质.总体来说,云阳县立体气候特征明显,环境质量较好,植被较高,生态气候良好,非常适宜开展避暑养生、气候康养等方面的旅游资源的开发.

Based on the meteorological observation data from 1957 to 2018 in Yunyang,with the temperature-humidity index and holiday climate index,the climate comfort degree and the suitable travel period was analyzed.The negative oxygen ion concentration data,the ambient air quality monitoring data and the water quality data of Yunyang in 2018 was also analyzed.The results show that spring,early summer and autumn were the most comfortable periods for Yunyang.The climate comfortable days were 138 days;the characteristics of the holiday-climate index of Yunyang was high in the middle and low in both ends,all year round,it was suitable for travel;the annual average concentration of negative oxygen ions of Yunyang was more than 1400/cm^(3),which reaches the standard of fresh air;the concentration of main air pollutants was lower than the national secondary standard,which shows a downward trend.The surface water quality of Yunyang was kept in class II throughout the year.Generally,Yunyang has obvious three-dimensional climate characteristics,good environmental quality,high vegetation,and good ecological climate,which was suitable for the development of tourism resources in summer regimen and climate health.
