Method for repairing lake water ecology by utilizing original ecology plant system

The invention provides a method for repairing lake water ecology by utilizing an original ecology plant system. Original ecology vegetation revetments of a trapezoidal structure and a lake three-dimensional vegetation system are involved, a soil organism system composed of arbors, shrubs, lawns and soil can reduce impacting of organic matter on riverways and lakes and eutrophication caused by theorganic matter like woods and lawns of both sides, and the fibrous roots of some shrubs can directly extend into water for absorbing nutrients in the water; the revetments are a natural transitional zone from a water area to a land area, combination of vegetation and soil improves the temperature and the humidity, and food supply is achieved; the revetments are stabilized, water and soil loss is avoided, the hardness, straightness and smooth features of the revetments are changed, and people can enjoy the green, soft and colorful appearance of the revetments; by adopting the lake three-dimensional vegetation system, t
