Problems solved by technology

Although these methods can evaluate the restoration effect of the mining area, it is difficult to conduct an accurate quantitative evaluation of the ecological benefits of the mining area, especially when there are many ecological types in the restored mine, it is difficult to conduct an effective quantitative evaluation

Embodiment 1

[0036] In the prior art, for the evaluation method of the ecological protection repair benefits of the mining area, such as expert scoring method, shadow engineering method, shadow price law, market value method, etc., although it is difficult to accurately quantify, due to the selectivity and large Most use requirements are sufficient, so those skilled in the art do not have an improved motivation for existing evaluation methods, which are only selected according to their own needs.

[0037]However, with the increase in the number of mining zones, if assessment of each mineral area within a large range, the existing evaluation method is not only slower than the efficiency, but it is difficult to quantify the results of the evaluation, resulting in an evaluation comparison. Non-high. In exchange, existing evaluation methods can only be evaluated similar to excellent, good, medium and worse, but the specific evaluation score is missing, so there are two drawbacks, first, for evalua...

Abstract

The invention belongs to the technical field of mining area restoration, and particularly relates to a mining area ecological protection restoration benefit evaluation method, which comprises the steps of S1, dividing various ecological types of a mining area into independent areas according to ecological type distribution in the mining area; s2, according to a preset water balance equation, the water conservation amount in each ecological type area is calculated, and the water conservation amount f of the mining area is obtained through summation; s3, according to a preset water and soil loss equation, the soil conservation amount f of the mining area is calculated; s4, according to a preset carbon fixation and oxygen release mechanism model, the fixed carbon dioxide amount f fixed carbon of the mining area is calculated; calculating the released oxygen amount f < oxygen release > according to f < carbon sequestration >; and S5, according to a preset restoration benefit algorithm, the ecological protection restoration benefit value F of the mining area is calculated according to f water conservation, f soil conservation, f carbon sequestration and f oxygen release. According to the method, the ecological protection and restoration benefits of the mining area can be accurately and quantitatively evaluated.

Description

Technical field [0001] The present invention belongs to the field of mine repair technology, and specifically, the present invention relates to a method of evaluating the evaluation method of ecological protection repair in mineral regions. Background technique [0002] The large-scale mining of the mine also brings a rich mineral resource, and it has also brought the ecological environment problem, especially in the hilly belt of minerals, mine mining is relatively serious, and wildlife plants are damaged, landslides, Mountain floods and other disasters and collapsed accidents occurred. With the increasing advancement of ecological civilization, mine ecological restoration has become an important environmental governance issue. [0003] Mine repair, that is, repairs the abandoned pollution of mining, and realizes the recovery of the destroyed ecological environment, and sustainable use of land resources. At present, the technical methods commonly used for the ecological protecti...
