The effects of macrophytes on lake ecosystem are analyzed, the biomass control and harvesting management measures for macrophytes are summarized, and the common methods on determining the biomass target for macrophytes restoration are discussed. Based on the growth characteristic of macrophytes, an assessment approach on the optimal biomass of macrophytes in decaying period and growth period, respectively, in shallow lakes using lake ecological model is proposed. The present research is of great significance for guiding the lake ecological restoration and its subsequent maintenance. It provides scientific support for improving the comprehensive evaluation standard of healthy lakes and the theory of lake ecological restoration.
