摘要:

我国湖泊湿地面积大, 动植物资源十分丰富, 但受人类活动干扰强烈, 退化较为严重。湖泊湿地生物多样性监测是湖泊湿地生物多样性保护和研究的重要环节。在一些发达国家相关的工作已较为成熟, 我国尚处于起步探索阶段。本文介绍了北美大湖湿地生物多样性监测项目的指标体系和实施方法, 旨在为建立我国的湖泊湿地生物多样性监测网络提供借鉴与启示。北美大湖湿地共设置约1,500个监测样点, 研究人员通过每年对水体环境和五大生物类群(植物、底栖无脊椎动物、鱼类、两栖类、鸟类)进行野外调查和数据采集, 构建生物完整性指数(index of biotic integrity, IBI), 以评价大湖湿地生物多样性和生态环境健康的现状及未来的变化趋势, 为湿地的保护和管理提供重要依据。北美大湖湿地生物多样性监测方法不但具有较强的科学性和系统性, 并且可操作性强, 对构建我国湖泊湿地的生物多样性监测方案有参考价值。

Abstract:

Lake wetlands are home to a wide variety of wildlife, including numerous species that are highly dependent on habitat and a big portion of them are classified as protected by law. However, lake wetlands are among the most functionally degraded ecosystems. Almost 40% of Chinese lake wetlands are threatened by various factors, including land development, input of pollutants, and hydrologic alterations. A monitoring network is essential for tracking changes in wetland biodiversity. Many developed countries have established regional or even national scale wetland monitoring systems, whereas China is still in the early stages of development. In this paper, we introduce indicators and implementing methods for coastal wetland biodiversity monitoring in the Great Lakes. Five biological groups (i.e. plants, macroinvertebrates, fishes, amphibians and birds) and water were sampled annually from c. 1,500 monitoring sites. Indices of biotic integrity (IBIs) were developed based on biological community data to assess the current status of and temporal trends in wetland health conditions. This project provides the scientific basis for biodiversity conservation and wetland management policy, and represents a good example for formulating a wetland biodiversity monitoring scheme in China.
