According to the theory of multiple stable states of shallow lake ecosystems, it is possible to speed the ecological restoration process by recovering aquatic vegetation in eutrophic lakes. In Wuli Lake, both emerged plant and floating-leaved plant could adapt to the eutrophic habitat, but submerged plant was limited by low light intensity at the lake bottom. Permanent e-merged plant community and floating-leaved plant community was built under natural conditions of Wuli Lake, and some submerged plant communities were set up in the enclosures where the water quality was improved and the underwater light intensity increased. The submerged plant community could not survive the summer for the high water temperature and high water level in the season. To make the habitat in Wuli Lake suitable to submerged plants one possible way is to control the water level and build shallow littoral zone by moving the fertile mud from the center area to the littoral zone. In the present studies, some usable techniques have been mastered for water quality control and aquatic vegetation recovery in shallow eutrophic lakes, and more detailed quantitative studies were needed on the relationship of structure and environmental function of aquatic vegetation.
