摘    要:从对湖泊富营养化评价的一般方法入手,综述了国内外有关湖泊富养化综合评价的一些方法,提出:营养状态指数法由于可对湖泊营养状态进行连续的数值化的分级,从而为湖泊富营养化机理的定量研究提供了坚实的基础,应是今后湖泊富营养化评价中的主要方法。

关 键 词:富营养化  营养状态指数  综合评价  湖泊  水体

Abstract:On the basis of general mcthods for cvaluating lake cutrophication, thc anthor summarized some comprehcnsivc assessmcnt n1cthods for lakc eutrophication reportcd at home and abroad. Lt is pointed out that the trophic statc index should be the major method for evaluating lake eu-trophication status, since it could provide a contlnuous numerical class of lake trophic statc and a rigorous foundation of quantitative studies of eutrophication mcchanism. After analyzing some determination methOds of weight distribution in thc comprehensivc indices, the anthor insists that the hierarchical analysis be (luite perfcct to dctcrn11ne wcights. This paper shows the weight distribution of TSI and its modifiers. Additionally, it is dlscussed in brief the relations between comprehensive eva1uation and othcr statistical methods such as clustcr analysis in thc last part of this paper.
Keywords:Eutrophication  trophic state index  comprehensive evaluation  hierarchical analysis  cluster analysis
