Embodiment 1

[0035] Build an ecological zone in areas with seawater salinity ≤ 20‰ and strong wave flow, where artificial sand replenishment has been arranged. The actual build process is as follows:

[0036] (1) Lay out ecological fence belts. Coastal side of beach erosion area figure 1 In method 2, two wave-shaped ecological belts are arranged with an interval of 5m. The details are as follows: ① Level the land at the place where the ecological fence will be arranged, and remove large pieces of plastic, stones, garbage and other excess materials to prevent the foundation of the wooden pile from being unstable. ②For piling, use wooden piles with a diameter of 0.3-0.5m and an interval of 2-5m. The length of the wooden piles in the soil / sediment is 2-5m, and the height of the wooden piles above the soil / sediment is 3-5m. Three rows of wooden piles are arranged on both sides of each ecological belt. ③ Bamboo with a diameter of 5-20 cm is placed horizontally and fixed on wooden stakes.

Embodiment 2

[0039] Build an ecological belt in areas with seawater salinity ≤ 30‰ and strong wave flow, where artificial sand replenishment has been arranged. The actual build process is as follows:

[0040] (1) Lay out ecological fences. Press on the beach side figure 1 Method 1 in the method is to lay out two ecological belts that are staggered forward and backward, and the details are as follows: ① Level the land where the ecological fence will be arranged, remove large pieces of plastic and stones and other garbage, and prevent the foundation of the wooden pile from being unstable. ②For piling, use wooden piles with a diameter of 0.3~0.5m and an interval of 1~2m. A stake belt is arranged on both sides of each ecological belt. ③Twigs with a diameter of 3 to 10 cm are bundled into piles and fixed horizontally on stakes.

[0041] (2) Vegetation planting: the layout width of the vegetation area is 20-30m. The amount of ecological substrate used is 1,500-2,000 tons / ha. Plants such as ...

Embodiment 3

[0043] Build an ecological zone in areas with seawater salinity ≤ 10‰ and weak wave flow, where artificial sand replenishment has been arranged. The actual build process is as follows:

[0044] (1) Lay out ecological fences. Press on the beach side figure 1 Method 1 in the method is to lay out two ecological belts that are staggered forward and backward, and the details are as follows: ① Level the land where the ecological fence will be arranged, remove large pieces of plastic and stones and other garbage, and prevent the foundation of the wooden pile from being unstable. ②For piling, use wooden piles with a diameter of 0.1-0.3m and an interval of 1-2m. The length of the wooden piles in the soil / sediment is 2-3m, and the height of the wooden piles above the soil / sediment is 2-3m. A row of wooden stakes is arranged on both sides of each ecological belt. ③Twigs with a diameter of 3 to 8 cm are bundled into piles, placed horizontally between stakes and fixed.

Abstract

The invention discloses an ecological zone construction method for reducing waves and reducing beach argillization, and belongs to the technical field of vegetation restoration ecology. The technicalproblem that in the prior art, a traditional engineering seawall cannot effectively deal with beach erosion and prevent beach argillization is solved. The method comprises the following steps that ecological fence zones which are continuously distributed in a wave shape or distributed in a front-back staggered mode are arranged in the direction of a coastline, at least two ecological fence zones are provided and are parallel to each other, and a vegetation area is formed between every two adjacent ecological fence zones; and vegetation zones are constructed in the vegetation areas, and the method for constructing the vegetation zones comprises the step of planting local plants.

Description

technical field [0001] The invention relates to a method for constructing an ecological belt for reducing waves and sandy beach silt, and belongs to the technical field of vegetation restoration ecology. Background technique [0002] In order to maintain the beach, at present, the beach restoration technology is usually used which combines the sand filling of the beach shoulder + hard engineering such as spur dam and submerged dam. However, from the perspective of actual effect, this traditional engineering seawall cannot fundamentally solve the problem of beach erosion, nor can it prevent the muddying of the beach in areas with high sediment input. In the design of beach sand replenishment projects, it is often only possible to construct breakwaters by means of numerical simulation on the basis of a small number of influencing factors such as meteorological, hydrological, and geological conditions. Due to the neglect of the local ecological environment balance in the const...
