物种多样性与生态系统功能关系的研究现状

目前，对于氮磷添加对物种多样性和生态功能关系的影响研究结果结论不一，本文通 过对国内外研究氮磷添加对物种多样性和生态系统功能及其两者间关系的影响进行总结:氮磷 共同作用会显著降低群落物种多样性，磷对群落物种多样性没有显著的影响；不同环境下氮磷 添加对植物生产力影响不同；物种多样性与生态系统功能间关系研究结论不统一，应结合环境 因子和研究尺度等多因素分析。

The status of the relationship between species diversity and ecosystem function

At present, the effects of nitrogen and phosphorus addition on species diversity and ecologi? cal function are different. In this paper, the effects of nitrogen and phosphorus addition on species diver? sity and ecosystem function and their relationship at home and abroad are summarized: the interaction of nitrogen and phosphorus can significantly reduce community species diversity, phosphorus has no significant effect on community species diversity, and nitrogen and phosphorus addition has different ef? fects on plant productivity under different environments. The research conclusions on the relationship between species diversity and ecosystem function are not uniform, and should be analyzed in combina? tion with environmental factors and research scales.
