摘要翻译，英语高手帮忙翻译下，机械和软件翻译的就别来了！急求，谢谢

为探讨氮沉降增加对小兴安岭地区典型阔叶红松林的影响，本研究以4个处理，分别为N0( N,0 kg hm-2a-1对照)、N1(N,30 kg hm-2a-1)、N2(N,60 kg hm-2a-1)、N3(N, kg hm-2a-1) 4分析混合凋落叶和土壤养分元素的动态变化，每个处理3个重复。分析的结果表明: 经过氮处理（N1、N2、N3）凋落物叶平均N 含量比N0处理分别高29.97%、15.58%、9.05%。相对于对照，表层土壤经过处理的全N含量分别增长了29.18%、34.93%、37.98%。尽管养分含量随着时间变化表现出一定的波动性，但氮沉降在一定程度上降低了凋落叶中K、C含量，土壤PH值、有机质、速效P和速效K含量随氮沉降水平增加呈下降趋势，表明掉落物和土壤对氮沉降的响应比较敏感。

Answer 1

To study the nitrogen deposition on the small Xingan mountain area the influence of typical broad-leaved Korean pine forest, in this study, 4, respectively ( N N0, 0 kg hm-2a-1 control), N1 ( N, 30 kg hm-2a-1 ), N2 ( N, 60 kg hm-2a-1 ), N3 ( N, kg hm-2a-1 ) 4 Analysis of mixed leaf litter and soil nutrient dynamic change, 3 replicates in each treatment. Analysis of the results showed that: after nitrogen treatment ( N1, N2, N3 ) litter Ye Pingjun N content than N0 respectively 29.97%, 15.58%, 9.05%. Relative to the control, soil surface treated the N content increased by 29.18%, 34.93%, 37.98%. Despite the nutrient content change over time showed some fluctuations, but nitrogen deposition in a certain extent reduced in K, C content in leaf litter, soil pH, organic matter, available P and available K content increased with nitrogen deposition level decreased, indicating falling object and soil nitrogen deposition on sensitive response.

跟我专业不对口，不过可以给你个建议，去cnki词典查查吧，有很多例句的。
