Embodiment Construction

[0007] In order to understand the suitable elevation for the growth of Spartina, we used the outer slope protection of the north wall of Dongjiang Beach Scenic Area to select a more suitable location, and carried out experimental planting from the daily high tide line of the slope protection to the low tidal flat. The planting area is about 100 square meters, and more than 300 Spartina plants are planted. Studies have shown that Spartina has very tenacious vitality. It can survive artificially planted on the existing low-elevation (daily high tide level below 1.5 meters) beaches on the eastern coastline of Dongjiang, and new leaves can be drawn out, and some plants can form ears. The research also shows that the survival of Spartina on the higher beach surface is better than that on the lower beach surface, and the tidal flat elevation suitable for Spartina to grow is 0.5m below the high tide line (the elevation of Dagu is about 3m). After the tidal flat elevation where Sparti...

Abstract

The invention combines the land reclamation epeirogenic engineering technology with the salt-tolerant plant greening technology for raising the beach face elevation of the land reclamation area intertidal zone for satisfying the growing requirement of the salt-tolerant plant and fast afforesting the intertidal zone. By consulting the cofferdams reclaimed project and adopting the principle of on-site mud balance, excavation and filling combination and flexible landscaping, the preset cement components with certain shape and size are adopted and spliced together in the intertidal zone according to the landscaping requirement, the amphibious excavator is adopted for filling the seabeach sludge after that the cement components are fixed, the salt-tolerant plant, as spartina growing in the intertidal zone is transplanted after that the seabeach sludge is filled. The muddy tidal flats fast afforestation technology for land reclamation epeirogenic area can quickly solve the problems that the land reclamation area intertidal zone forming time is short, the recovery time depending on natural ecology is long and the existing greening technology cannot meet the greening construction requirement of the region.

Description

technical field [0001] The invention belongs to the field of landscape greening, in particular to a method for landscaping of muddy tidal flats in coastal land reclamation areas or tidal flat areas. Background technique [0002] With the acceleration of the construction of Tianjin Binhai New Area, the land reclamation area has increased year by year, and the natural coastline has been basically replaced by artificially built stone or earth embankments, and there is not much left. In July 2010, the length of the natural coastline was 68.49km, accounting for only 26.05% of the coastline, while the length of the artificial coastline increased to 194.41km. According to the plan, by 2020, the length of the natural coastline will be only 38.64km, and the proportion of artificial coastline will increase to 84.93%. [0003] The Dongjiang Port Area of ​​Tianjin Port is formed by artificial land reclamation using dredged spoil, with a planned area of ​​30km 2 , 10.7km long from nort...
