| 中文摘要 |
| 以野外监测数据为基础,应用模糊综合评判方法掌握大气污染物的变化规律,然后采用熏气试验测定植被对污染物的净化速率,建立大气污染物的植被控制模型,并以此提出了益阳市大气主要污染物的植被负荷及绿化设计。 |
| 英文摘要 |
| According to the results of monitoring air pollution factors for one year in Yiyang City, Hunan Province, the variations of atmospheric environment were clarified by means of fuzzy mathematics. Meanwhile the artificial fumigation tests were carried out to select the higher tolerant plants and to measure the pollutant-absorption rate.. In consideration of these factors, a vegetation controllingmodel for air pollution was put forward. f = 2.22×10-4(Ci-C) ·α-1·h f-plant coverratio; α-1-SO2-plant absorption rate;h-heightof air mixing layer; Ci-real concentraction; C-standard concentration.Directed by the model, the plant species and afforestation pattern were designed, and the capacity of plants for SO2 and the amount of SO2 released in Yiyang were established. |
