【摘要】 根据污染物迁移转化的基本原理,通过实地调查和取样分析,对ZJ燃煤发电厂建成前和建成运行13年后周围陆地土壤和农作物中污染物含量进行比较,分析了燃煤发电工程对陆地生态环境的影响程度。结果表明,燃煤发电工程排放的烟气污染周围陆地生态环境,其中主要是SO₂降落地面引起土壤pH下降,改变了土壤离子组成。文中提出了减免这种影响的措施和途径。更多还原

【Abstract】 To understanding pollutant variation and conversion, the pollutant contents in soil and crops near ZJ coal-burning power plant in 1988 and in 2002 were studied by sampling in field, with the aim to analyze the impact of pollutants discharged from the coal-burning power plant on land ecological system. The results showed that smoke discharged by the power plant had polluted the land ecological environment. When SO2, the main pollutant, fell to the ground, soil pH decreased, so the composition of the ions in soil changed. Moreover, some methods to reduce the impact were proposed.更多还原
