However, due to the increase of human activities, the natural wetlands in many waters in my country are gradually decreasing or even disappearing. On the vast waters, birds cannot find a foothold, which is not convenient for them to stop and prey during long-distance migration, which has caused serious damage to the survival of some wintering migratory birds. threatened
The development of artificial wetlands is of great significance to birds and certain animals and plants in the long run, but artificial wetlands cannot be effective immediately in a short period of time. It is a long-term, gradual project

Embodiment Construction
[0012] Control attached figure 1 , its structure is that several ecological floating bed units 1 and submerged plant planting piles 2 are placed together sequentially along the direction of water flow, and the number of ecological floating bed units 1 is combined according to the conditions of local waters.
[0013] Control attached figure 2 , the structure is that the submerged plant planting pile 2 is placed on the same straight line as the fixed wooden pile 9 of the floating bed along the direction of the water flow about 1m apart, and the water plant fixed pile 2 is composed of a plurality of wooden piles 9 whose height is lower than the water surface The siege is cylindrical and filled with crushed stones 10. Submerged plants 11 are planted on the top of the crushed stones and cylindrical gabions 12 are erected. The gaps between the crushed stones are convenient for the roots of submerged plants 11 to grow. The surface of the block is easy to form a biofilm composed of ...

Abstract
The invention relates to a large water area phytal zone migratory bird perching and water purification composite system. The system is characterized in that a plurality of ecological floating beds 1 and submerged plant planting piles 2 are arranged along the water flow direction in turn; and the number of the ecological floating beds 1 is determined according to the local water area conditions. The invention has the following advantages: the system can adapt to the water area of which the water level changes largely; the phytal zone of the large water area can be used as the habitat of birds;and the planted plants can play an active role in the water purification and a harmonious natural ecological landscape can be created.
Description
technical field [0001] The invention relates to a composite system for migratory bird habitat and water purification in shallow water areas of large water areas. Background technique [0002] The ecological floating bed technology fixes aquatic plants or some terrestrial plants on the floating bed. Through the absorption and degradation of plant roots and microorganisms attached to the roots, nutrients such as nitrogen and phosphorus can be removed to effectively control the eutrophication of water bodies. The biological floating bed has the characteristics of directly removing pollutants from the water body, making full use of the water surface without occupying land, etc.; it can be applied in water bodies with various water depth conditions, and the cost is low, and the operation and management are relatively easy. Up to now, ecological floating bed technology has become an important water quality improvement technology worldwide, and has been successfully applied in many...
