物种多样性-生态系统功能关系的影响因素

The factors influencing relationship between species diversity and ecosystem functioning

物种多样性和生态系统功能的关系是生态学研究的重要科学问题。综述影响物种多样性和生态系统功能关系的因素,可为今后的相关研究提供借鉴和参考。物种多样性-生态系统功能之间的关系受多种因素影响,实验类型的不同引起物种多样性-生态系统功能关系的改变;小规模时空尺度下的人工调控实验结论对于区域范围的普遍意义具有较大的局限性;天然草地中常见的放牧、施肥等干扰也影响着物种多样性-生态系统功能之间的关系。生态系统内部潜在的能量流动和信息传递及其相互间的作用对物种多样性-生态系统功能的影响将是今后生物多样性研究所面临的主要挑战。

The relationship between species diversity and ecosystem functioning is an important field in ecological science.A general review on the factors influencing relationship between species diversity and ecosystem function can provide useful reference for relevant researchers.This review indicated that the relationship between species diversity and ecosystem functioning was affected by many factors,such as experimental types,spatial-temporal scale and disturbance regimes.Difference in the experimental types caused different conclusions of the relationships.Results and explanations from the small spatial-temporal manipulated experiment did not reflect the situation of large-scale observational results.The disturbances in the natural grassland,such as grazing and fertilization,also affected the relationship between species diversity and ecosystem functioning.The effects of potential energy flow and information transfer along with their interactions in the ecosystem on the relationship was a major challenge in the insight into biodiversity in the future.
