摘　　要：磷是湖泊营养状况的重要指标本文综述了国外对沉积物中不同形态磷的分级提取的发展概况，分析比较了各提取法的优缺点，阐述了不同形态砖的生态学意义，并总结了沉积物磷分级分析的发展趋势，以期为国内相关研究提供参考和借鉴．The development of speciation and fractionation schemes of phosphorus from various sediments were outlined together with the elucidation of the advantages or disadvantages of the schemes, and the ecological significance of different forms of phosphorus; suggestions for further researches were presented in this field. They can be of great help to the relevant researches that have been less conducted in China.
