摘　　要：随着经济的发展,酸雨已成为全球性的环境污染问题,我国酸雨污染出现的频率和强度也在逐年增加。如何在酸雨影响下保护农作物产量是当前酸雨相关研究的热点问题。实验选择了我国东北地区典型的农作物小白菜作为研究对象。通过模拟实验,分析了酸雨胁迫下小白菜的生理生长指标的变化,并验证土壤中Ca(NO_3)_2的添加是否可以维持酸雨条件下小白菜的产量。研究结果表明酸雨和土壤中的Ca(NO_3)_2均会影响小白菜的部分生长生理特性,酸雨的存在会影响小白菜的可食用部分的产量等指标。但是当土壤中Ca(NO_3)_2浓度增加时,会降低酸雨的影响,间接地减弱了酸雨对小白菜产量的影响。因此可在酸雨影响较为强烈的地区,通过增加土壤中Ca(NO_3)_2浓度,以降低酸雨对小白菜的影响。With the rapid of developing economy in China,acid rain has been a global pollution problem,and its frequency and intensity is increasing. How to protect the crop yield under the acid rain stress becomes a hot topic. Brassica Chinensis L. is chosen as the typical crop in northeast of China. Based on two rounds of simulation experiment,the growth and physiological characteristics of Brassica Chinensis L. under the acid rain stress were gotten,and try to research whether added Ca（NO3）2to the soil could maintain the yield of Brassica Chinensis L. The results shown that acid rain and Ca（NO3）2in the soil could influence the growth and physiological characteristics of Brassica Chinensis L. by changing the contents concentrations of different kinds of Ca（NO3）2in the Brassica Chinensis L. The acid rain could decrease the yield of Brassica Chinensis L. While,the additional Ca（NO3）2in the soil could improve the yield of Brassica Chinensis L. and decrease the influence caused by acid rain. In all,the additional Ca（NO3）2to soil could maintain the yield of Brassica Chinensis L in the field where influenced by acid rain.
