摘要
伴随着工农业的快速发展,环境问题日益凸显,森林生态系统服务功能衰退。生物多样性和生产力、生产力和森林生态系统服务功能之间均有一定的正相关性,基于因果路径分析理论,生物多样性通过作用于生产力这一中介变量来提高森林生态系统服务功能。而目前我国生物多样性面临着来自人类和自然的双重威胁,建议从推进生物多样性主流化、完善法律监管力度、促进保护手段创新方面减轻这一威胁。
With the rapid development of industry and agriculture, environmental problems have become prominent and the service function of forest ecosystem has declined. There is a positive correlation be. tween biodiversity and productivity, productivity and forest ecosystem service function. According to the causal path analysis theory, biodiversity improves forest ecosystem service function by acting on productivi. ty as an intermediary variable.At present, China's biodiversity is facing serious threats from human and na. ture. It is suggested to ease the pressure by promoting the mainstreaming of biodiversity, improving the le. gal supervision and promoting the innovation of protection means.
