| 摘 要： | 控制和降低城市上空ＳＯ２的环境浓度对于改善城市环境，促进城市生态的良性循环具有十分重要的意义。本文从上海市绿化三维量分布模型、与ＳＯ２浓度分布模型的相关分析入手，以季节变化作为对比因子，讨论了城市绿化植物群的数量及分布对城市上空ＳＯ２浓度分布的宏观影响；并据此提出了可有效地控制城市上空ＳＯ２浓度的绿地建设的基本原则。

| Abstract: | Controlling and decreasing the environmental density of sulphur dioxide (SO2) in the air have a importantsignificance in both improvement of environmental quality and promotion of reasonable circle of ecology in city area. Inthis paper with analyzing the relationship between the environmental quality and the greenery which is described by the3-dimensional vegetable quantity, the macro influence by the amount and distribution of urban greenery on the SO2 den-sity in the air was discussed through the overlapping model of the relative difference of the 3-dimensional vegetablequantity and the difference of SO2 density between summer and winter in Shanghai, and then put forward several essen-tial principles of making the city green which could effectively decrease SO2 density in the air. |
