Method for planting submerged vegetation Vallisneria denseserrulata in medium-subsidence wetland of coal mining subsidence area

Abstract

The invention discloses a method for planting submerged vegetation Vallisneria denseserrulata in a medium-subsidence wetland of a coal mining subsidence area. The method comprises steps of selecting proper Vallisneria denseserrulata seedlings and preserving the same as needed, planting the Vallisneria denseserrulata seedlings in a pre-processed engineering area in the medium-subsidence wetland ofa coal mining subsidence area in specific time and according to a certain interval and by corresponding seedling clips, monitoring ecological indexes of Vallisneria denseserrulata plant clusters in the engineering area after the plantation, and managing a water level during a growth period. With the plantation of highly-effective and primary producer submerged vegetation, an ecological service function of an aquatic ecological system in the medium-subsidence wetland, and utilization rate of the medium-subsidence wetland can be improved.

Description

technical field [0001] The invention relates to the technical field of ecological engineering, in particular to a method for constructing the submerged vegetation of the submerged vegetation in the moderate subsidence wetland in the coal mining subsidence area. Background technique [0002] The Lianghuai mining area is an important energy base in East China and one of the 14 large coal bases planned by the state. Lianghuai Coal Mine mainly includes Huaibei Mining Area and Huainan Coalfield. [0003] The Huaibei mining area is one of the coal fields with the largest remaining coal resource reserves in eastern my country. The Huaibei mining area involves the three cities of Huaibei, Bozhou, and Suzhou. The scope of the coal mine is 40-150km long from east to west, about 135km wide from north to south, and covers an area of ​​about 12,350km 2 . According to the development characteristics and geographical location of the geological structure, the mining area is roughly divide...

Problems solved by technology

[0004] At present, it is still in the early stage of the unsteady stage, the water depth is mostly within 3 meters, the land reclamation is difficult, and the land utilization rate is low; the aquatic plant community formed has a single species, with water peanuts and water candles as the dominant species, and low biodiversity , cannot play the service function of the lake ecosystem
