IBI应用于湿地生态健康评价的研究进展

综述了生物完整性指数(IBI)指数的构建方法,概述了IBI在不同湿地类型中及国内外的应用情况.IBI在河流、溪流和湖泊湿地中应用最广泛,采用最多的指示生物是无脊椎动物和鱼类,主要用于评估人类活动、气候变化等对湿地生态健康的影响及湿地保护管理措施的成效.提出今后须着重考虑对IBI构建方法的优化,同时与遥感、地统计等其他技术手段相结合,拓展IBI方法的空间适用范围,使其成为不同尺度湿地生态监测的有效手段.

The Recent Advances in Applications of Index of Biotic Integrity on the Assessment of Wetland Ecological Health

The concept of biotic integrity,the procedures of developing an IBI and the application of IBIs in different wetland ecosystems are introduced.IBIs have been most widely applied to rivers,streams and lakes for assessing the impacts of human activities and climate change on wetland ecological health.The most commonly used biological indicators include macroinvertebrates and fishes.It is found that there are large methodological differences in defining reference conditions,in the choice of IBI metrics and metric scoring,and that optimizing the methods for IBI development should be emphasized in future research.It is also suggested that combining IBI with other techniques such as remote sensing and geostatistics would largely expand the applicability of IBI on wetland ecological monitoring at different spatial scales.
