Embodiment Construction

[0036] The present invention will be further elaborated below in conjunction with the accompanying drawings, so as to better understand the content of the present invention. But protection scope of the present invention is not limited to following embodiment

[0037] This embodiment is based on the National Twelfth Five-Year Water Special Project, and the Taihu Lake area in Wuxi City, Jiangsu Province is the restoration object. This area is a lakeside belt extending from the Taihu Lake Expressway to the Taihu Lake waters, and belongs to a typical embankment-type lakeside belt. The basement condition is poor, the terrain changes are complicated, the vegetation coverage is low, and the soil erosion is serious. After utilizing the multi-habitat three-dimensional vegetation lakeside belt construction method of the present invention, the plant Simpson diversity index and the Shannon-Weiner index float around 0.66 and 2.0 respectively, and the biomass is 2103g / m 2 , with a 60% incr...

Abstract

The invention discloses a levee-type lakeside zone multi-niche three-dimensional vegetation construction method. The method comprises a multi-niche design and a phytoremediation mode design. According to the method, aiming at a degenerative levee-type lakeside zone, based on above environmental factor characteristics, the theory and technology of the modern ecology and the ecological engineering are applied, a lakeside terrestrial-aquatic transverse zone is divided reasonably, a suitable ecological habitat construction mode is put forward specifically, meanwhile various ecological habitat characteristics are taken into account, and a compatible aquatic plant vertical distribution community structure recovering method and a plant community recovering method are put forward.

Description

technical field [0001] The invention relates to a method for constructing multi-habitat three-dimensional vegetation in a dike-type lakeside zone, and belongs to the technical field of environmental protection and ecological restoration. Background technique [0002] Domestic research on ecological restoration of the lakeside zone began at the beginning of the 21st century, mainly focusing on the Erhai Lake Basin, Taihu Lake Basin and the Three Gorges Reservoir. In the Erhai Lake Basin, an ecological restoration plan for the Erhai lakeside belt has been compiled, and the water-land ecotone has been divided according to land use types. From 2003 to 2008, a large number of scholars conducted a large number of analyzes on the water-land ecotone of the Three Gorges Reservoir, and carried out field restoration tests to study the water purification mechanism of the water-land ecotone. During the "Eleventh Five-Year Plan" period, the survey and investigation of the entire watershe...
