苏、浙、皖、闽、湘、鄂、赣7省酸沉降农业危害——酸沉降农业生态综合危害分析

Effect of acidic deposition on agriculture of Jiangsu, Zhejiang, Anhui,Fujian, Hunan, Hubei and Jiangxi provinces—damage to agricultural ecosystem.

为了解酸沉降对农业生态系统的影响，通过模拟酸沉降对苏、浙、皖、闽、湘、鄂、赣７省主要农作物的影响，在数学模型的基础上得出了农作物受酸沉降危害的减产基准值，分析了７省农业损失构成，提出了划分酸沉降农业生态危害的等级标准，并绘制出７省酸沉降农业综合生态危害图。

Based on model, effect of acidic deposition on major corps in Jiangsu, Zhejiang, Anhui, Fujian, Hunan, Hubei And Jiangxi Provinces was assessed, and a series of yield lose criteria of acidic deposition on crops were established. Farmland was divided into five types according to the degree of acidic damage to ecosystem and was plotted in 1°×1° grid of longitude and latitude.
