This paper would like to present a comprehensive re-port on the role and application of the ecological stoichiometry in the hydrolysis ecosystems. For this purpose,it is inclined to make a comprehensive discussion of the achievements of the ecological stoichiometry on the growth rates,the homeostasis,the metabolic situation produced,the population and the bio-communities in the water-bodies with the ever-increasing problems to be dealt with in the area in recent years. As is known,the aquatic plants tend to hold their own inherent chemical constitution stable and accommodate themselves to their own surrounding environment. And,in doing so,they would like to adjust their own intracellular elements well-balanced,so as to make themselves well in accord with the changing environment,thus,leading to their own growth with their population and communities,though some of the key objective resources may affect their ecological essential changes as a result of the outside environment changes. Therefore,such changes can be categorized into some kinds of ecological balanced change attributed to the evolutionary changes of somewhat multiple chemical elements. Thus,it can be seen that the review we have made here can help to provide for evidence to support the inherent relation between the chemical stoichiometric of the aquatic plants and their growth. In addition,more or less academic evidence in the technical literature that can help to demonstrate that the stoichiometric change may also affect the inherent evolution of the biological genes,resulting in their changes in physique and bio-nature. From the point of view of the bio-evolutionary aspect,it would be better to predict that such changes can attribute to the responses of the changing nutrients the aquatic plants get from the environment. What is more,the stoichiometry effect on the aquatic plants tends to reveal in a lot od large-scale ecological patterns,including the remarkable bio-geo-chemical cycle interaction for C： N： P stoichiometry. Thus,the perspective of the ecological stoichiometry may imply a more systematic understanding of somewhat changes of complicated chemical substances. It can also be supposed that the aquatic plants are subject to the habitable mechanism under the new environment conditions. Thus,it can be concluded that the ecological stoichiometry is supposed to imply a great potential for new in-sights of the ecological processes and a great prospect to resolve the long-time myth in the aquatic plants. Furthermore,this paper can also offer some clue to the relevant existing issues,which can be expected to. increase the understanding of the ecological stoichiometric and promote its studies and application in the aquatic plant ecosystems.
