胁迫生态学研究进展

介绍了胁迫及胁迫生态学的定义，划分了胁迫的种类，阐述了胁迫生态学的研究意义和主要研究内容。受胁生态系统的症状包括营养循环、初级生产力、物种多样性、优势种群个体大小、演替方向、发病率和种群数量等的变化。在一定程度和一定时段内，生态系统的平衡机制可以缓解胁迫的影响；一旦胁迫超过自稳定能力，生态系统将进一步退化甚至发生不可逆转的崩溃。胁迫生态学可以为生态系统诊断、生态系统管理、生态系统恢复和重建提供理论依据。

Progress in Stress Ecology.

By introducing the definitions of stress and stress ecology and stress classification, the significance and principal contents of the stress ecology were expounded. The symptoms of stressed ecosystems include changes in nutrient cycling, primary productivity, species diversity, individual size of dominant populations, succession direction, incidence of diseases, size of population, and so on. The influences of stress can be mitigated by ecosystem homeostasis mechanisms to some extent and within a certain period. Inability to cope can lead to further dysfunction and perhaps to irreversible breakdown of the ecosystem. Stress ecology can be used as theoretical basis for diagnosis, management, restoration and rehabilitation of ecosystems.
