| Abstract: | This paper reports the results of restoration experiments of aquatic vegetation carried out in the demonstration enclosures which are situated at three different subregions in a eutrophic shallow freshwater lake, Donghu Lake of Wuhan. It is found that the r-selected submerged plants,i. e., Vallisnerlti sp., MyrioPhyllum spicatum, Potamogeton crispus, and Najas marina can recover spontaneously or through the artificial introduction in' the enclosures. The strategies for the recovery of aquatic vegetation of Donghu Lake have been put forward on the basis of the study of the succession dynamics of aquatic plant community and the restoration test results. First of all, the ceasing of stock of herbivorous fish and reduction of standing stock of these fishes must be carried out at once, which may enhance the recovery of submerged vegetation in the sublakes such as Niuchaohu, Houhu and Tanglinhu. The K-selected ones,such as Potamogeton maackianus and Elndea canadensis should be introduced into the above-mentioned less-polluted sublakes for the optimization of species composition and community structure. In order to restore the submerged macrophytes in the eutrophic or hypereutrophic sublakes and bays such as Guozhenghu,the engineering measures must be taken to reduce and/or remove the internal and external nutrient loading combined with the biomanipulation. The r-selected submerged plants should be transplanted at first, and then the K-selected ones may be restored after the improvement of water quality. |
