氮沉降对亚热带森林倒木分解主场效应的影响
Effect of N deposition on the home-field advantage of wood decomposition in a subtropical forest
[目的]氮(N)可以通过改变微生物和动物群落的丰度和活性来影响森林生态系统的功能。氮沉降对倒木分解的主场优势(HFA)效应的影响尚不清楚。[方法]在本研究中,在氮沉积量位居世界前列的中国亚热带地区,设置三个不同水平的氮沉降处理(对照(N0)、60(N1)和 120(N2)kg N ha-1 yr-1),进行了为期 24 个月的野外倒木木材交互迁移实验。使用不同尺寸的网袋划分土壤生物群对倒木分解HFA效应的影响。[结果]我们发现N1 处理通过提高倒…查看全部>>
[Objective]Nitrogen(N)can influence the functions of forest ecosystems by altering the abundance and activity of microbial and faunal communities.The impact of N deposition on the home-field advantage(HFA)effect of dead wood decomposition remains unclear.[Method]In this study,a 24-month field reciprocal wood translocation experiment was conducted with three levels of N deposition(control(N0),60(N1)and 120(N2)kg N ha-1 yr-1)in both Platycarya strobilacea(PL)f…查看全部>>
