摘要/Abstract

摘要： 生物多样性与生态系统功能的关系已成为重大的科学问题呈现在生态学界。大量的研究表明, 生物多样性对系统生产力、分解性、养分循环以及稳定性等多种功能均有重要影响。本研究在众多研究的基础上, 就生物多样性的基本内容——物种多样性对生态系统功能的2个方面,即生产力和入侵性的关系模式、作用机理、存在的争议, 以及时空尺度对其的影响作一综述。通过生物多样性与生态系统功能关系基本理论的探讨, 阐明生物多样性对生态系统功能的重要影响及潜在机理, 以期为相关研究者提供科学参考, 以促进我国的生物多样性研究。

Abstract: The relationship between biodiversity and ecosystem functioning has emerged as a central issue in ecology. A number of researchers have shown that diversity has an important influence on ecosystem functioning, including productivity, decomposition, nutrient cycling, and stability. A review of a great deal of scientific literature on relationship patterns, mechanisms, ongoing debate between initial components of biodiversity-species diversity, on two ecosystem functioning-productivity and invasibility, and on the effects of spatio-temporal scales is summarized. Through basic theoretical synthesizing, the relationship between diversity and productivity, invasibility, along with the mechanisms controlling them were elucidated. This review will provide a valuable reference source for research and will promote biodiversity research in China.
