Ecological recovering method of sublittoral zone Zosteraceae sea grass bed

Abstract

The invention relates to a recovering and rebuilding technique of a sea grass bed, in particular to a ecological recovering method of a sublittoral zone Zosteraceae sea grass bed, which is characterized in that: clay and fine sand are made into mud barrel, Zosteraceae plants are filled inside the mud barrel, the mud barrel is fulfilled with fine sand, an opening of the mud barrel is sealed, the mud barrel with the Zosteraceae plants is thrown into an appropriate sea area so as to carry out the ecological recovery of the Zeosteraceae sea grass bed, and the density of the Zosteraceae is 50 to 200 per square meters. Due to the adoption of the ecological recovering method, the problem that sea grass is difficult to transplant in deep seabed of the sublitoral zone can be solved, and the recovery or rebuilding of deep sea Zosteraceae sea grass bed can be conveniently and rapidly carried out by also adopting a simple and effective Zosteraceae transplanting method. Materials utilized in the method are free from polluting the sea are.

Description

technical field [0001] The invention relates to seagrass field restoration and reconstruction technology, in particular to an ecological restoration method for subtidal eelgrass seagrass field. Background technique [0002] Seagrass meadows ecosystem, mangrove forest and coral reef ecosystem are considered to be three typical offshore marine ecosystems. And international research results show that the ecological service value of seagrass fields is significantly higher than that of mangroves and coral reefs. Seagrass is the only angiosperm that submerges in shallow water, and differentiates into organs such as roots, stems, leaves, flowers and seeds. Lush seagrass fields are like forests on land, an important symbol of a healthy marine environment, and are precious "undersea grasslands" or "undersea forests". Seagrass fields are high-productivity areas that can provide good habitats, nursery grounds and shelters for marine organisms such as fish, shrimp, crab, and shellfish...
