High water table coal area ponding secondary wetland landscape construction method

Abstract

The invention discloses a high water table coal area ponding secondary wetland landscape construction method. The method step comprises the following steps: dividing coal district small area sporadic ponding region and large area contiguous ponding region, small area sporadic ponding region and large area contiguous ponding region construction method, constructing a pollution impermeable dyke, constructing a lake enlarging area impermeable layer, establishing a side slope retaining wall, water system balance and maintenance and vegetation and landscape configuration. Through the adoption of the method, the high water table coal area ponding secondary wetland landscape in two types of the small area sporadic ponding region and the large area contiguous ponding region can be constructed from regional scale, not only the ecological benefit can be improved through local microclimate regulation, humidity control, water source purification, water body improvement, and biodiversity conservation, but also the economic benefit can be improved by providing agricultural products and improving peripheral soil value, thereby further improving the service value of the ecological system.

Description

technical field [0001] The invention belongs to the technical field of ecological landscape, and in particular relates to a landscape construction method, in particular to a water-logged secondary wetland landscape construction method in a high-water level coal mining area. Background technique [0002] Coal mining is one of the main causes of land destruction. According to incomplete statistics, as of the end of 2013, the area of ​​land subsidence caused by coal mining has reached 1.56 million hectares, and it is still increasing at a rate of 33,000 to 47,000 hectares every year. Among them, the subsidence land area around the residential area is about 600,000 hectares, seriously affecting the human living environment. High water level coal mining areas are mainly distributed in the plains of eastern my country. Due to the high ground water level, the surface will subside and accumulate water after coal mining, thus forming a unique ecological environment of water and land ...

Problems solved by technology

[0004] In the past, the commonly used methods were mainly to use filling and reclamation as agricultural land or construction land, or to dig deep into various waterlogged areas to become aquaculture waters, but there was a lack of landscape construction of waterlogged wetlands in high-water-level coal mining areas on a regional scale.
