摘　　要：为了准确预警和评价兰州市及周边区域空气质量,本文采用定点定位原则,对南北两山人工林区空气负氧离子浓度实时监测和数据分析研究,以期对城市及周边空气质量监测和环境保护提供基础理论依据。结果表明:(1)人工林地空气质量达到清新标准,而闹市区远远低于两山林地空气负氧离子含量,空气质量较差。(2)两山人工林地空气负氧离子浓呈现季节性差异、林分差异、温度差异、湿度差异等变化规律:在晴朗高温天气下,负氧离子浓度随湿度的增加而增加。(4)不同的天气条件影响某一地点的负氧离子浓度。(5)监测地点植被群落、温度和湿度对空气负氧离子浓度影响显著。In order to accurate early warning and evaluation of Lanzhou and the surrounding area air quality. In this paper, the fixed positioning principle, according to both the south-north hills artificial forest air negative oxygen ion concentration real-time monitoring and data analysis, in order to the city and the surrounding air quality monitoring and environmental protection provides a basic theory. The results show that the artificial forest air quality reach the standard fresh, and downtown is far below the two mountain forest air negative oxygen ion content, the air quality is poor. The two mountains and artificial woodland air negative oxygen ion concentration present season difference, stand difference, difference in temperature, humidity difference four major changes: in hot and sunny weather, negative oxygen ion concentration increases with the increase of humidity. A place of negative oxygen ion concentration of different weather conditions.The effect of monitoring sites of vegetation communities, temperature and humidity on the air concentration of negative oxygen ions significantly.
