摘要:
天然水域,尤其是富营养的浅水湖泊,沉积物中磷的释放是蓝藻水华发生、形成和持续生长的重要因素.分析沉积物中磷的赋存形态转化及其潜在生态效应,有助于理解沉积物中磷的迁移转化过程及其与湖泊富营养化之间的关系.本文综述国内湖泊水域中磷的主要形态、来源和转化过程以及其生物有效性的研究进展.重点讨论了近5年来中国东部浅水湖泊沉积物磷的形态分析、转化和生物有效性评估的现状,以及沉积物中磷形态与浅水湖泊富营养化之间的潜在联系.

Abstract:
Release of phosphorus from sediment of natural waters, especially from those shallow lakes, are essential process in the growth and development of algae bloom. Studies on species transformation and changes in bioavailability will be helpful in understanding geochemical cycling of phosphorus in lakes and its relation to lake eutrophication. This paper summarized the recent research progresses on phosphorus speciation, transformation, phosphorus cycling in Chinese lakes, and the relevant changes in bioavailability. Recently, special attention was given to issues such as different species in sediments in eastern China shallow lakes because there were only a few works on the lakes in the west, south and north of China. Relevant research was also less found on the brackish lakes in the plateaus or lagoons in the estuarine and coastal zones. In addition, it is a pity that no work could make a breakthrough on the methods of phosphorus fractionation. There was a little advance in the study on the transformation of phosphorus species, the assessment of phosphorus release risk and its bioavailability. For example, the pattern of phosphorus release from different types of sediments in response to pH changes was unveiled; the approaches for laboratory and in situ measurements of bioavailable forms of phosphorus were developed, as well as the relationship between acid soluble organic phosphorus species and eutrophication were proposed. In a eutrophic shallow lake, there is an interaction relationship between algal blooms and internal phosphorus release. However, this interaction is well related to human disturbance and influenced by some natural factors, e. g. hydrodynamic processes and stormy waves. Much beneficial exploration was done on the phosphorus speciation, mobilization and transformation between sediment and water interface in many lakes in China, and a lot of hypothesises as well as new methods were also proposed in recent studies, but it still need more experimental data to testify.
Key words:  Chinese lakes  phosphorus speciation  fractionation  bioavailability  eutrophication
