近海生态系统健康状况评价的研究进展

Offshore ecosystem health status assessment: A review

在可持续发展观的推动下,水域生态系统健康问题已引起各界的广泛重视.其中,河流、湖泊等水域的健康评价已开展很多,但对近海生态系统健康的研究还处于探讨阶段.本文在调研国内外大量文献的基础上,对近海生态系统健康的概念进行辨析,总结了近海生态系统健康状况评价的方法、指标筛选原则和研究思路等,并系统地列举了近海生态系统状况健康评价的一些相关量化指标.最后,针对目前近海生态系统健康研究领域存在的主要问题,提出了近海生态系统健康研究的发展方向,认为今后开展近海生态系统健康状况评价研究还需在概念及内涵剖析、评价指标筛选、评价尺度选取和评价方法集成等方面进一步加强.

With the promotion of the concept of sustainable development, the issues of aquatic eco- system health attract substantial attention, and considerable work has been carried out on the health assessment of waters, e.g. , rivers and lakes. However, the health assessment of offshore ecosystem is still at its exploratory stage. Based on the investigations on the related references at home and abroad, this paper analyzed the concepts of offshore ecosystem health assessment, summarized the main methods for the assessment, the principles for screening related indicators, and the research philosophy, and systematically listed the quantitative indices for the assessment. Aiming at the main existing issues in the researches of offshore ecosystem health, the future research directions about the offshore ecosystem health were suggested. It was considered that the concept and connotation analyses, the screening of assessment indicators, the choice of assessment scale, and the integration of assessment methods should be further strengthened to improve the assessment of offshore ecosys- tem health.
