Abstract:Great attentions have been paid on submersed macrophytes restoration in recent years. This paper summarized the current research advance in submersed macrophytes restoration and systematically analyzed the environmental factors affecting the growth of submersed macrophytes. Light intensity was recognized as the restricting factor in the growth of submersed macrophytes.Factors including nutrient contents, deposited sediments, water current, suspended sediments and temperature had a distinct effect on submersed macrophytes growth. A optimal value range of each factor was existed to meet the best growing state of submersed macrophytes, which changed with the types and growth periods of the macrophytes. The impacts of inserted algae, heavy metals and pH on the growth were little than that of the above factors. The problems existed in present researches were as follows: (a) Dynamic and quantificational studies of the impacts of some environmental factors on submersed macrophytes growth were insufficient; (b) There was lack of integrated investigations considering several factors which were of complex relationships; (c) Fewer field experiments were conducted and the laboratory experiment results couldn′t give a efficient guide for submersed macrophytes restoration.
