摘要
为探讨海南省五大自然保护地负氧离子浓度与环境因素的相关性,为我国热带地区森林公园的开发利用提供理论参考,利用海南省生态环境厅及各市县政府环境质量公报数据,分析2010—2020年间负氧离子浓度与其所在市县的空气质量变化情况,并进行相关性分析。结果表明,其间年均负氧离子浓度呈上升趋势,空气污染物PM_(2.5)、PM_(10)、O_(3)、SO_(2)、NO_(2)、CO等指标总体呈下降趋势;五指山国家级自然保护区负氧离子浓度与SO_(2)呈现正相关(P<0.01);五大自然保护地空气中负氧离子浓度整体水平较高,空气质量等级达到一级;负氧离子浓度总体呈现出夏秋季高、春冬季低的季节特征。
This study was to explore the correlation between negative oxygen ion concentration and environmental factors in five major natural protected areas in Hainan Province,and provide theoretical references for the development and utilization of forest parks in tropical areas in China.The data from the Department of Ecology and Environment of Hainan Province and the environmental quality bulletins of municipal and county governments was used to analyze the changes of negative oxygen ion concentrations in the five major forest parks and the air quality of the cities and counties in which the parks were located from 2010 to 2020.Correlation analysis was conducted.The results showed that the annual average negative oxygen ion concentration showed an increasing trend,and the air pollutants PM_(2.5),PM_(10),O_3,SO_2,NO_2,CO and other indicators showed a general decreasing trend.The concentration of negative oxygen ions in Wuzhishan National Nature Reserve was positively correlated with SO_(2)(P<0.01).The overall level of negative oxygen ion concentration in the five major forest parks was good,and the air quality reached the first level.The overall negative oxygen ion concentration showed the seasonal characteristics of high in summer and autumn and low in spring and winter.
