生物多样性影响农业生态系统功能及其机制研究进展

Research Advance on Biodiversity Affecting Agro-ecosystem Function and Its Mechanism

根据生物多样性影响生态系统功能某些作用机制,对生物多样性现在或未来可能对农业生态系统生产力的某些促进机理进行探讨。基于生态位互补角度简述了农业生物多样性对环境资源(非生物因素)的互补利用;并借鉴经济学理论剖析农业生态系统中生物多样性"投资组合效应"的经济生态学意义;同时,结合最新的生态位构建理论与进化动力学模型,对生物多样性(生物因素)的生态动力学机制进行分析;而作为农业生态系统中扮演重要角色的人,更应注重农业生物多样性保护与利用的关系。

According to some mechanisms of biodiversity affecting ecosystem functioning,in this review, agro-ecosystem productivity were promoted by some mechanisms of biodiversity in now or future. The first was niche complementarity scale, aiming at environmental resource were made use of complementarity of agro-biodiversity; and depending on economical theory,economical ecological significance of ＂Portfolio effect＂ of biodiversity in agro-ecosystem was thoroughly studied ; at the same time, by using up-to-date niche construction theories and evolution dynamical models, the ecological dynamical mechanisms of biodiversity was analyzed. In agro-ecosystem,the most important part was man,should play a vital role and pay attention to the relationship between protection and application of agro-biodiversity.
