摘要
湿地生态系统健康是指生态系统随着时间的进程有活力并且能维持其组织结构及自主性,在外界胁迫下容易恢复;评估湿地生态系统健康的标准有活力、恢复力、组织、生态系统服务功能的维持、管理选择、外部输入减少、对邻近系统的影响及人类健康影响等8个方面,建立生态系统健康评估指标的第一步是指标选择原则的确定;根据生态系统健康评估的目的和指标筛选的原则,寻求对管理景观中的湿地生态系统健康进行整体性评估的合适指标。
The concept of ecosystem health is reviewed and its relationship with related ecological discipline is discussed. Ecosystem health refers to the level of an ecosystem being active, maintaining its organization and autonomy over time, performing its function normally, and being resilient to stress. The main assessment concepts of ecosystem health include vigor resilience, organization, maintenance of ecosystem service, management options, reduction of external input, damage to neighboring systems, and human health effects. The first step in the structure of indicators to assess ecosystem health should be the determination of precise indicator principles. According to the purpose of assessment and the principles of selecting indicator, discussed the suitable indicators to synthetically assess the wetland ecosystem health in governed landscape.
