Problems solved by technology

However, the current lack of research and theory on the selection and allocation of plants for ecological restoration in mines has led to blind introduction of species in the process of ecological restoration in many mines, unreasonable plant selection, and poor ecological restoration effects.

Embodiment Construction

[0066] The present invention will be further described in detail below in conjunction with examples, and the protection scope of the claims of the present invention is not limited by the examples.

[0067] The invention relates to a screening method for ecological restoration plants in abandoned mines, in particular to a comprehensive screening method for ecological restoration plants in abandoned mines. The invention comprehensively evaluates the mine ecological restoration plants, so as to provide a reference basis for the selection of plant species for the mine ecological restoration. The method of the present invention is to analyze the requirements of the mine environment on the plant characteristics, and establishes a hierarchical structure model: a criterion layer formed by ecological performance, biological characteristics, economic value, ornamental value and market value and an index layer composed of 17 indicators; The weight value of each index effectively fills th...

Abstract

The invention discloses a waste mine ecological restoration plant screening method. The method comprises the following steps: (1) establishing a hierarchical structure model; (2) constructing a judgment matrix, judging the relative importance of each index of each layer to obtain the weight of each index, and judging the consistency; (3) determining an index scoring standard, and evaluating and assigning values to the plants; and (4) calculating comprehensive evaluation indexes, and recommending ecological restoration plant varieties of the abandoned mine. According to the method, an index system is hierarchically constructed; the relationship between the target and the index is clear; meanwhile, a scientific basis can be provided for screening of mine ecological restoration plants from the five aspects of ecological performance, biological characteristics, economic value, ornamental value and market value through a hierarchical method, the effect and significance of the plants in mineecological restoration can be objectively and truly reflected, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a method for ecological restoration of abandoned mines, in particular to a method for screening plants for ecological restoration of abandoned mines, and belongs to the technical field of ecological restoration engineering. Background technique [0002] With the rapid economic growth, the demand for mineral resources continues to increase, and the problems of environmental pollution and ecological damage caused by mining development are also increasing day by day. Mineral mining is mainly divided into open-pit mining and underground mining. Among them, open-pit mining has the greatest damage to the ecosystem structure and function of the mine. It not only affects the natural landscape, causes environmental pollution, but also induces landslides, causing soil erosion and other geological disasters. . Therefore, how to restore and rebuild the degraded mine ecosystem has become a topic of widespread concern around the world. The...
