Embodiment Construction

[0025] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0026] This embodiment takes the construction of the secondary wetland landscape of Jiuli Lake in Xuzhou City as an example. Jiuli Lake is located in the north of Xuzhou City. Due to its high water level, Jiuli Lake was transformed from a coal mining subsidence water accumulation area. Such as figure 1 As shown, the wetland landscape construction steps are as follows:

[0027] (1) According to the "Xuzhou Jiuli Lake Wetland Park Master Plan", according to the method of combining subsidence land management and ecological restoration and adhering to the principle of "be suitable for agriculture, be suitable for agriculture, be suitable for forest, be suitable for forest, be suitable for water, be water, be suitable for construction, be built" According to different conditions such as the shape, soil type, stratum structure, degree of stability, and w...

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 ...
