Plant proportioning method for ecological restoration of coal mine area based on remote sensing image

Abstract

The invention discloses a plant proportioning method for ecological restoration of a coal mine area based on remote sensing images, and relates to the technical field of ecological restoration. The method comprises the following operation steps: 1, dividing auxiliary data of different site conditions into different types by adopting a remote sensing image technology; and 2, comparing the auxiliary data of different site conditions with plant species composition under different vegetation coverage change trends, and determining key plant types required for vegetation restoration and reconstruction in each site condition and vegetation coverage change trend region. The method is suitable for ecological restoration, by improving the vegetation proportion, optimizing the phytoremediation proportion for different site conditions and conducting vegetation distribution, the mine ecological restoration sustainability and efficiency are improved, good ecological benefits are generated, reasonable vegetation proportion matching is achieved, the symbiosis is good, the ecological sustainability is excellent, and good popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a plant proportioning method for ecological restoration in a coal mining area based on remote sensing images. Background technique [0002] In recent years, with the large-scale, high-intensity and long-term coal mining process, a large amount of land has been destroyed and plant site conditions have been damaged, such as subsidence pits, tailings and waste rock fields. Under natural conditions, the damaged ecological environment has recovered. It will take decades or even hundreds of years, so the restoration of the ecological environment in coal mining areas based on artificial guidance has become extremely important. [0003] Although the ecological restoration and management of open-pit mines have achieved rapid development, there are generally problems such as single vegetation type, relatively fragile ecological structure, and low vegetation survival rate, ma...

Problems solved by technology

[0003] Although the ecological restoration and governance of open-pit mines have achieved rapid development, there are generally problems such as single vegetation types, relatively fragile ecological structures, and low vegetation survival rates, which make it difficult to meet the sustainability of ecological restoration and social and economic development.
