Abstract: The results of ecological survey of effects of an accident of Cl2 pollution on plants and crops in Fushun city were reported.(1)The closer to the pollution source,the more seriously the plants were harmed. The harm degrees are different from plant to plant.(2)The yields of vegetable (Chine cabbage, turnips) and rice in the polluted area decreased 67%-15% and 38%-5% respectively, and the rate of output positively correlated to the distance between the areas and the pollution source.(3)The sudden harm to trees with strong tolerance such as popular, willow and Acacia by Cl2 pollution can be recovered soon and no long-term harm was observed. The studies showed that the ecological survey plays an important role in evaluating and dealing with pollution accidents.
