Repair method for tidal flat fishery habitat of Yangtze estuary
The invention provides a Yangtze River estuary tidal flat fishery habitat restoration method which is characterized in that restoration is carried out in a mode of combining'plant planting and a three-dimensional floating bed 'on the basis of hydrological deposition dynamic difference of different elevation areas of a Yangtze River estuary tidal flat wetland and difference characteristics of water logging resistance of different plants. The area with the beach face elevation smaller than 2.5 m and not suitable for natural growth of plants serves as a three-dimensional floating bed area, and a plant three-dimensional floating bed mode is adopted for repairing; the area larger than 2.5 m serves as a plant planting area, a plant transplanting planting mode is adopted for repairing, cyperaceae plants are planted in the area with the elevation range of 2.5-3 m, and gramineous plants are planted in the area larger than 3 m. According to the method, the bad influence of hydrological conditions of an estuary tidal flat area is broken through, and ecological restoration of the damaged and degraded Yangtze River estuary tidal flat habitat is realized, so that the damaged habitat restoration problem that the hydrological conditions are complex and are difficult to restore by natural laws is solved; restoration of ecological functions of important fishery organism spawning fields, bait fields, migration channels and the like at the Yangtze estuary is realized.
本发明提供了一种长江口潮滩渔业生境修复方法，基于长江口潮滩湿地不同高程区水文沉积动力差异和不同植物耐水淹的差异特点，利用“植物种植+立体浮床”相结合的方式进行修复。将滩面高程小于2.5m不适于植物自然生长的区域作为立体浮床区，采用植物立体浮床的模式进行修复；大于2.5m的区域作为植物种植区，采用植物的移栽种植方式进行修复，其中高程范围在2.5‑3m的区域种植莎草科植物，大于3m的区域种植禾本科植物。本发明突破了河口潮滩区域水文条件的恶劣影响，实现对受到破坏和退化的长江口潮滩生境进行生态修复，以解决水文条件复杂、靠自然规律难以恢复的受损生境修复问题，实现长江口重要渔业生物产卵场、索饵场、洄游通道等生态功能的修复。
