The N input from rainfall in HPA was about 3 to 4 times higher than that in LPA and CK. However, the biomass of vegetables in HPA was decreased by up to 40%, when compared with that in CK, thus leading to a significant decrease in N output through crop harvesting. As a result, a large proportion of N was sequestrated in the soils subjected to acid rain, which subsequently enhanced nitrate leaching posing a risk to water environment.

在酸沉降重污染区，降水输入系统的氮远大于轻污染区和对照区（约3~4倍），同时因酸雨危害，蔬菜产量明显低于对照区，仅为对照区产量的60%，使系统中通过作物收获的氮输出减少，结果导致大量氮滞留于土壤中并以硝态氮等形态淋失，给水环境带来了氮污染风险。
