摘 要: 研究了生态系统的结构、功能与过程,提出了生态系统可持续发展的概念模型;明确定义了生态系统网络,提出它由生物子网络、物质循环子网络、经济子网络和社会子网络构成;提出了生态系统网络的层次性、幂律的度分布、鲁棒性、脆弱性与扰动恢复、时空动态性、网络与流的协同演化等性质和特征;建立了流域生态系统网络模型,并对生态与经济过程耦合机制以及基于生态系统网络的集成管理决策进行了分析。 Based on the research of the structures,functions and processes,one sustainable development conceptual model of ecosystem was proposed.The ecosystem network was explicitly defined,and its sub-networks including biological network,material cycle network,economic network and social network were also analyzed.The ecosystem network has some special properties such as hierarchies,power-low of degree,frangibility and restore,dynamics,co-evolution of flow and structure.As an example,one watershed ecosystem network model was established,based on which the coupling mechanisms of ecological and economic processes as well as the integrative management decision were studied.
