【摘要】 于1984年6月至1985年9月,对哈尔滨热电总厂绿地环境效益进行了调查研究。尽管该厂绿地是零星小块分布,但绿地环境效益还是较明显的。 研究结果表明:绿地可减尘14—17％;衰减噪声3.9—5.10dB（A）;降低日平均气温0.5—1.4℃;增高日平均相对湿度6.1—13.8％。 树木叶片能吸收大气中的SO₂,某些树木叶片含硫量与大气SO₂浓度相关,可作为大气污染的指示树种。更多还原

【Abstract】 The environmental effects of the green areas in Harbin Heat power plant were investigated during June 1984 to September 1985.Although the green areas in plant were scattered in small plot in the plant, their environmental effects were relatively obvious.The investigation showed that the green areas could reduced the amount of dust particulates in the air at the rate of 14—17%, the noise level 3.9—5.1db （A）, the everage diurnal air temperature by 0.5—1.4℃ and increased the daily humidity by 6.1—13.8%.The paper also indicated that SO₂ in the atmosphere was absorbed by trees. The sulfur content in the tree closely related to the sulfur level in the atmosphere, so some tree species can be used as ind icators of pollutants in air.更多还原
