摘要: 随着“长江大保护”的推进,长江流域水体中浮游生物的生长状态成为日益热门的话题。硅作为六大生源要素之一,是影响浮游生物生长繁殖的要素之一,对流域生态系统的结构和稳定起到至关重要的作用。首先介绍了河流中硅的形态分类,讨论了对不同形态硅的研究意义。随后综述了国内外研究成果,对长江流域硅含量的时空分布特征进行整理分析,探讨可能影响河流、水库及河口硅含量分布的因素,对比分析了长江与国内外其他河流硅含量差异的原因,展望了长江流域硅含量当前研究的不足及未来研究方向。研究成果可为硅元素对长江流域浮游生物生长的影响等相应研究提供思路与建议。

Abstract: With the promotion of “Great Protection of the Yangtze River”, the growth status of plankton in the Yangtze River water body has become an increasingly hot topic. Silicon, as one of the six source elements, is one of the factors that affect the growth and reproduction of plankton, and plays a vital role in the structure and stability of watershed ecosystem. In this paper, the morphological classification of silicon in rivers is introduced at first, and the significance of researching different forms of silicon is discussed. Subsequently, recent research findings in China and abroad are summarized, including the spatial and temporal distribution patterns of silicon concentration in Yangtze River Basin, and the factors which might affect silicon concentration distribution in rivers, reservoirs, and estuaries. In addition, the causes for the differences in silicon content between the Yangtze River and other rivers are compared and examined, the shortcomings of current researches are analyzed, and future research fields are prospected. The present research offers ideas and suggestions for corresponding research on the influence of silicon on the growth of plankton in the Yangtze River Basin.

Key words: waters of Yangtze River Basin, BSi, DSi, silicon content, water environment
