Methods of Vegetation Restoration of Silt and Silt Coastal Tidal Flats

Abstract

The invention relates to a silty coastal tidal flat vegetation restoration method. The method is characterized by selecting supratidal zones with weaker tidal effects and high tidal zones not subjected to flood irrigation by the middle tide level as vegetation construction zones, firstly building tide barriers and water channels running through vegetation restoration zones, optimizing hydrology and the sediment environment of a project zone, then constructing a water-salt control mode of high platform fields+field drainage and irrigation system+micro-furrow planting or high platform fields+drains+high ridge deep furrow planting, introducing freshwater, carrying out water-saving irrigation and high-efficiency salt leaching, creating a low-salt freshwater environment suitable for vegetation growth, meanwhile, paying attention to pumping tidewater and supplementing freshwater after high tide invasion, then selecting salt resistant pioneer vegetation to carry out the vegetation restoration cultivation technique comprising micro-furrow seeding and salt-avoiding seeding of suaeda salsa, reed rhizome transplanting and tamarix chinensis seedling raising and transplanting, and carrying out management and protection. The problems of stronger tidal effects on silty coastal tidal flats, bad sediment environment and low vegetation coverage caused by high soil salinity can be effectively solved by adopting the method.

Description

technical field [0001] The invention relates to a method for restoring vegetation on silty muddy coastal tidal flats, and belongs to the technical field of ecological environment management and utilization. Background technique [0002] Because the coastal tidal flats are close to the sea, the tidal action is frequent, and the soil salinity is high, most of which are above 2%, and most of them are barren and barren lands. With the rapid development of coastal economy, the rapid expansion of cities and the increasingly prominent demand for ecological environment improvement, the improvement of regional ecological environment has become particularly important. Its rational development and utilization not only improves the ecological environment of coastal tidal flats, but also has important theoretical and practical significance for the increase of cultivated land resources. [0003] Publication No. CN101715664A discloses a method for comprehensive and rapid treatment of sali...
