长江三峡库区森林生态系统服务形成与驱动机制

The research on ecosystem services is showed solicitude for increasingly serious global ecological and environmental issues. Now ecosystem service becomes core of ecological research. Ecological barrier zone of three Georges Reservoir area has sensitive and frangible environment and it is seriously urgent to maintain and promote ecosystem service of the area. It is a difficult and eventful challenge to optimize management of multiple ecosystem services in Three Georges Reservoir area. The team had studied on forest landscape pattern process and ecosystem services and dynamics in typical area and found the situation of sensitive environment with interferences in Three Georges Reservoir area. The forest in this area plays an important role for water and soil conservation and shelter, etc. The project is intended to establish evaluation system for forest ecosystem services of Three Georges Reservoir area with main services assisted by factors of social production and humanity, build dynamical response database between forest ecosystem services and landscape patterns, forest structure, disturbing factors, respectively. With the database weights of the factors are computed and the process of forest ecosystem services is showed and their mechanism is revealed. Ecosystem services tradoffs or ecosystem services synergies is judged. This research should provide scientific support for the effective ecosystem services in Three Georges Reservoir area.

全球生态环境问题日益严重，使得生态系统服务研究备受关注，已是当前生态学研究的核心内容。三峡水库生态屏障区生态环境敏感而且脆弱，维持和促进其生态系统服务迫在眉睫，如何同时优化管理多种生态系统服务是当前三峡库区的一项重要挑战。本研究尝试在已有对三峡库区森林景观格局-过程研究以及库区典型区域森林生态服务功能与动态研究的基础之上，针对三峡库区生态环境脆弱以及干扰因素复杂等特点，以库区森林的主体生态服务功能（涵养水源、保持水土、森林防护等）为依托，兼顾区域社会生产以及人文等功能，建立三峡库区森林生态系统服务功能评估体系，构建库区森林生态系统服务功能与景观格局、森林结构类型以及干扰因素之间的动态响应库，确定各影响因子的权重表现，揭示库区森林生态系统服务功能的形成过程及驱动机制，探讨库区生态系统服务功能权衡、协同作用的特征表现，为三峡库区森林生态系统服务功能的最大有效发挥提供科学依据和理论指导。
