Embodiment 1

[0052] The implementation site is located in the west coastal waters of Shahe River, Shenzhen Bay, Nanshan District, Shenzhen, and the experiment period is from August 2016 to September 2017.

[0053] Investigate the natural conditions of the mangrove at the implementation site, and measure the water quality indicators in each area of ​​the mangrove at the implementation site: inorganic nitrogen DIN, active phosphate DIP, heavy metal (Cd cadmium, Pb lead, Cr chromium, Cu copper, Zn zinc) content; Record the size of wind waves and measure soil nutrient indicators: organic matter, total nitrogen, and total phosphorus TP, as shown in Table 1. According to the data obtained from the survey, the mangrove forests are divided into regions to determine the areas that need ecological restoration.

[0054] The collection and analysis of the samples were carried out in accordance with the national standard GB / T 12763.4-2007. In the inorganic nitrogen, the indophenol blue method was used ...

Embodiment 2

[0069] The implementation site is located in Gaolan Port, Zhuhai City, and the experiment period is from June 2019 to July 2020.

[0070] Investigate the natural conditions of the mangrove at the implementation site, and measure the water quality indicators in each area of ​​the mangrove at the implementation site: inorganic nitrogen DIN, active phosphate DIP, heavy metal (Cd cadmium, Pb lead, Cr chromium, Cu copper, Zn zinc) content; Record the size of wind waves and measure soil nutrient indicators: organic matter, total nitrogen, and total phosphorus TP, as shown in Table 2. According to the data obtained from the survey, the mangrove forests are divided into regions to determine the areas that need ecological restoration.

Abstract

The invention discloses a mangrove forest ecological restoration method. The mangrove forest ecological restoration method comprises the following steps that firstly, environmental characteristics of a mangrove forest restoration area are investigated and measured, and the environmental characteristics comprise water environment characteristics, soil quality characteristics and wind wave magnitude; the mangrove forest restoration area is divided according to data obtained by investigation, and an area needing ecological restoration is determined; composite microbial strains are thrown or indigenous mangrove plants are planted for purifying sewage in the area needing water environment ecological restoration to improve the water quality; soil remediation is carried out in the area needing soil ecological restoration; local mangrove seedlings are planted and reinforced in the area needing ecological restoration according to magnitude of wind waves; and the mangrove forest restoration area is regularly monitored and maintained, and the plant growth state is observed. Through a microbial restoration technology and a mangrove forest ecological restoration technology, the survival rate of mangrove plants is increased, the water quality is purified, soil nutrients are improved, degradation of a mangrove forest ecological system is effectively restrained, and biological diversity is improved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a method for ecological restoration of mangroves. Background technique [0002] Wetlands are one of the ecosystems with important environmental functions and the habitats of various organisms on the earth. The wetland environment is composed of wetland hydrology, wetland biogeochemical cycle, and the adaptation and transformation of organisms to the wetland. In the wetland environment, various factors interact and depend on each other to form the overall function of the wetland environment. As a transition zone between water and land, wetlands have huge environmental regulation functions and ecological benefits. Together with forests and oceans, wetlands are known as the three major ecosystems in the world. The means of production and living plays an irreplaceable role in other systems. It is one of the most important natural resources and living environment for h...
