Embodiment 1

[0107] Step 1. The section of the plain river near the first riparian zone where the flow velocity is less than 0.4m / s is preliminarily selected as the benthic habitat construction section, and the length of the benthic habitat construction section is 230m;

[0108] Step 2. At the upstream of the river section where the benthic habitat is constructed, a plurality of porous rockfill weirs are constructed along the extension direction of the first riparian zone, wherein any one of the porous rockfill weirs is from the first bank The length of the belt extending to Hanoi is 2.0m, and the distance between two adjacent porous rockfill dams is 10m; a total of 8 porous rockfill dams are set up; close between two porous rockfill dams The waters of the first riparian zone are transplanted with multiple patches of cattails and / or calamus to form an aquatic plant community, wherein the extension of the aquatic plant community on part of the first riparian zone is at least 40m, and the transp...

Abstract

The invention discloses a plain river benthic animal habitat construction method. The plain river benthic animal habitat construction method comprises the following steps of preliminarily selecting abenthic animal habitat construction river segment; constructing a plurality of porous rock mound barrages in the extending direction of a first river riparian zone at the upstream of the benthic animal habitat construction river segment, transplanting cattails and / or calami in multiple spots in the water area, close to the first river riparian zone, between every two adjacent porous rock mound barrages to construct an aquatic plant community; arranging a plurality of sedge square blocks on the water surface of the slow running water area behind the multiple porous rock mound barrages at intervals and spreading multiple cobble spot blocks on a riverbed; spreading a plurality of height adjustable river benthic animal avoiding devices at the downstream river surface of the benthic animal habitat construction river segment at intervals; charging aboriginal benthic mollusks at the benthic animal habitat construction river segment. Through the plain river benthic animal habitat constructionmethod, the habitat quality of benthic animals in a river can be quickly and effectively improved, and then the diversity of the benthic animal community at the benthic animal habitat construction river segment is improved.

Description

Technical field [0001] The invention relates to the technical field of river ecology research, in particular to a method for constructing a benthic habitat. Background technique [0002] In recent years, with social and economic development and population growth, the development of water resources and aquatic biological resources has increased unprecedentedly, and the pressure on the ecological environment of rivers has increased, sewage discharge, water conservancy projects, sand mining, water diversion and irrigation Other human activities have destroyed the habitat of aquatic organisms. Coupled with human overfishing and abnormal climate, the benthic habitat quality and biodiversity of plain rivers and rivers have declined. Summary of the invention [0003] An object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages described later. [0004] Another object of the present invention is to provide a method for constru...
