生物多样性与针叶林生态系统过程的关系

在过去10年中，生物多样性与生态系统过程的关系成为生态学中最具争议和挑战性的话题。生态学家们围绕植物组成和多样性与生态系统过程的关系、生物多样性与陆地生态系统的生物地球化学循环的关系、土壤生物多样性赇生态系统过程的影响、生态系统的功能多样性和组成对生态系统过程的影响、生物多样性与生态系统的稳定性以及生物多样性与生态系统过程对全球变化的响应等方面做了大量的开创性研究。川西亚高山针叶林是我国的生物多样性宝库和世界生物多样性的热点地区。迄今为止，有关川西亚高山针叶林生物多样性和生态过程的研究还相当有限，有关生物多样性与生态系统过程关系的研究尚未见报道。因此，建议在未来川西亚高山针叶林生态过程研究中加强生物多样性与针叶林生产力的关系，生物多样性和生物地球化学循环的关系、土壤生物多样性与生态系统过程的互动、地下／地上部分生物多样性的关系、生物多样性和生态过程对全球变化的响应等研究。

Relationships Between Biodiversity and Processes of Coniferous Forest Ecosystem

In the past decade, relationship between biodiversity and ecosystem process have been regarded as the most challenging and controversial topics in ecology field. A lot of innovative researches focus on linkage between plant species composition and diversity and ecosystem productivity, between biodiversity and biogeochemical cycle, functional group composition and diversity, biodiversity and ecosystem stability, and responses of biodiversity to global change etc. The subalpine coniferous forests in western Sichuan are biodiversity hotspot. So far there is a lack of knowledge on these relationships. Therefore,it was suggested that studies on the ecosystem process of subalpine coniferous forests should focus on these issues in the future.
