本研究应用生态化学计量学理论，探讨沉水植物中C、N、P、S、Si的相互作用，以及它们对富营养化的响应。结果表明，沉水植物具有相对较低的C、Si和N：P，除C外，沉水植物组织中N、P、S和Si耦合良好。相对而言，水分对组织中N、P、S和Si的影响大于泥沙。水深沉水植物的立场有很强的关系，组织C，支持光：营养假说。研究结果表明，低光照和低组织硅浓度可能是决定长江中下游沿着富营养化湖泊沉水植物命运的关键因素。因此，提高水体透明度是恢复浑浊富营养化湖泊沉水植物的必要措施。
The study, using ecological stoichiometry theory, is to document how C, N, P, S and Si interact in submerged macrophytes and whether/how they respond to eutrophication. Results showed that submerged macrophytes have relatively low C, Si and N:P. Tissue N, P, S and Si except C coupled well in submerged macrophytes. Tissue N, P, S and Si were relatively more affected by water than sediment. Water depth at which submerged macrophytes stand had strong relationship with tissue C, which supports light:nutrient hypothesis. Based on our results, we concluded that low light and low tissue Si concentration probably are the key factors in determining the fates of submerged macrophytes in eutrophic lakes along the middle and lower reaches of the Yangtze River. We suggest that enhancement of water transparency, is a necessary method to restore submerged macrophytes in turbid and eutrophic lakes.
