Embodiment 1

[0039] A method for constructing a low-maintenance ecological wetland, comprising the following steps:

[0040] Step 1. Ecological survey: Use the groundwater source detector to measure the source of groundwater, select the area with dense springs as the base point, and diverge from the base point to the surroundings. Use lime powder to draw the outline of the lake body on the project site according to the design drawings, and then carry out pile points Piling after layout;

[0041] Step 2. Build an artificial lake: Excavate the artificial lake wetland 11 with excavators, the effective water depth range is 8m, set up drainage outlets and water storage channels, remove debris at the bottom of the lake, install nozzles vertically at springs, and lay geotechnical anti-seepage membranes. Do a good job of anti-seepage at the bottom of the lake, and set up two plant corridors 18 in the lake. The plant corridors 18 are straight structures, and each plant corridor 18 is filled with el...

Abstract

The invention discloses a construction method of a low-maintenance ecological wetland. The construction method comprises the following steps of 1, performing ecological exploration; 2, constructing an artificial lake; 3, constructing the wetland around the lake; 4, improving wetland soil; 5, planting wetland plants; and 6, constructing hydrologic ecology; According to the construction method of the low-maintenance ecological wetland, the survival rate of plants and the purification capacity of a water body are greatly improved through reasonable plant selection and low-maintenance ecological configuration on the basis of the self-adjusting capacity and the self-organizing capacity of an ecological system, the purpose of water conservation is achieved by conserving water and soil and preventing water and soil loss, and the interference and investment of manpower are reduced, so that an ecological wetland system with low maintenance cost is constructed.

Description

technical field [0001] The invention relates to the field of environmental governance, in particular to a method for constructing a low-maintenance ecological wetland. Background technique [0002] The Guangdong-Hong Kong-Macao Greater Bay Area is rich in wetland water resources. Wetlands such as lakes and rivers can effectively alleviate the urban heat island effect, protect water resources and biodiversity, and provide a good living environment and recreational space, which is of great significance to economic and social development. With the development of urban processes and the irrational use of water bodies, land and other resources, environmental problems have become increasingly prominent. At the same time, pollutants brought by plant litter, rainwater runoff and air dust fall into natural water bodies such as lakes and rivers. In the process, the aquatic ecosystem has been greatly damaged. Relevant information shows that more than 90% of my country's urban park wet...
