摘要
通过对抚顺西露天煤矿闭坑复绿工程实施前后场内重点区域环境空气质量状况跟踪检测,分析复绿对矿坑周边环境空气质量的影响。结果表明,项目开展前后,PM_(10)、PM_(2.5)、氮氧化物浓度都在不同程度上有所下降,而负氧离子浓度呈逐步上升趋势。矿坑复绿在防风固沙、减少扬尘等方面非常有成效,同时绿植的碳汇效果明显,很大程度上改善了周边环境和空气质量。
In this paper,the influence of green restoration on the ambient air quality around the mine is analyzed by tracking and detecting the ambient air quality in the key areas before and after the implementation of the project.The results showed that the concentrations of PM_(10),PM_(2.5) and nitrogen oxides decreased to varying degrees before and after the project,while the concentration of negative oxygen ions showed a gradual upward trend.The regreening of the mine is very effective in preventing wind and fixing sand,reducing dust and so on.At the same time,the carbon sink effect of green plants is obvious,which greatly improves the air quality of the surrounding environment.
