生态完整性评价概念及应用

生态完整性具有丰富的内涵和很大的应用空间,对资源管理和生态评价有很重要的意义。介绍了生态完整性概念的多样性及内涵辨析,生态完整性评价在生态系统中的应用。水生生态系统完整性评价方法较成熟,陆地生态系统指标选取单一,湿地生态系统和其他生态系统需要建立完整性评价框架。水利工程和交通工程造成生物多样性、景观格局下降,为采掘类工程生态完整性评价提供了指数方法,并提出当前存在的一些问题和今后的研究发展方向。

Ecological integrity has rich connotation and great application space,which is very important to the management of resources and ecological evaluation. This paper has introduced the diversity of the concept of ecological integrity and analyzed its connotation,and the application of ecological integrity assessment in ecological system. The ecological integrity assessment method of aquatic ecosystem is more mature,the selection index of terrestrial ecosystem is single,the wetland ecosystem and other ecosystems need to establish a complete evaluation framework. The water conservancy project and traffic engineering may cause a decline in biodiversity and landscape pattern,and there provides the index of method for the evaluation of ecological integrity of mining projects. At last,there are some existing problems and future research directions are put forward.
