Embodiment

[0031] To a surface mine reclamation area surface mine reclamation area as an example of ecosystem resilience measure is calculated.

[0032] like figure 1 As shown in a surface mine reclamation zone ecosystem recovery force measurement method, comprising:

[0033] S1: impact indicators based on open-pit mine reclamation area belong to restore ecosystem functions, the establishment of open pit reclamation area ecosystem restoration hierarchical model of force measure; hierarchy includes: target layer a, b rule layer and index layer c;

[0034] Target layer a ecological restoration force evaluation target; Guidelines for layer (b) comprises: atmospheric b1, terrain conditions b2, hydrology b3, soil conditions b4, community health b5, vegetation status rhizosphere microorganisms B6; index layer (c) comprises: PM2. 5c1, PM10c2, TSPc3, gradient c4, slope length c5, groundwater c6, groundwater mineralization c7, soil moisture c8, soil pHc9, soil organic matter c10, available phosphorus...

Abstract

The invention discloses a method for measuring the restoring force of an ecological system in a strip mine reclamation area. The method comprises the following steps: establishing a hierarchical structure model for measuring the restoring force of the ecological system in the strip mine reclamation area; constructing a judgment matrix to obtain a weight vector of the judgment matrix, and calculating the weight of each index in the measured value of the ecosystem restoring force of the strip mine reclamation area; performing relative value operation on the actually measured data of each index in the index layer in the reclamation area and the undisturbed background area, and determining the score of each index in the index layer; and finally, measuring and calculating the ecosystem restoring force of the strip mine reclamation area. According to the method, the weight of each index in the measured value of the ecosystem restoring force of the strip mine reclamation area is calculated through a hierarchical structure model; and relative value operation is carried out on the measured data of each index in the reclamation area and the undisturbed background area to determine the score of each index in the index layer, so that the evaluation result is more accurate and comprehensive, and a theoretical reference can be provided for ecological restoration effect evaluation.

Description

Technical field [0001] The present invention relates to ecological protection and restoration techniques, and in particular, to a surface mine reclamation zone ecosystem Measuring Method recovery force. Background technique [0002] Previous reviews index calculation open mine reclamation area ecosystems are using absolute values, but different areas of natural conditions, water resources, topography, soil quality and other differences, resulting in a large vegetation in different parts of the original habitat conditions differences. Ecosystem resilience is the ability to restore the original function of the system is disturbed, so that only the surface mine reclamation area of ​​ecosystem indicators to evaluate the absolute value beyond measure resilience of ecosystems surface mine reclamation area. [0003] Chinese Patent (application No. 201810905154.3) discloses a reclamation method of evaluation, the processor and the storage medium, comprising: obtaining, and right above ev...
