摘要

[目的

]

综合评价山西省大同市某井工煤矿区的生态安全状况，为同类井工煤矿区生态保护提供科学依据。 [方法

]

以该井工煤矿区2017—2021年的各项指标为依据，基于PSR模型从压力、状态以及响应3个方面构建煤矿区生态安全评价指标体系，使用合作博弈法确定组合权重系数，利用可拓云模型来分析该矿区生态安全状况。 [结果

]

压力指标下人口自然增长率(C

)的评价等级为Ⅲ级，表明人口出生率和死亡率分布不均衡，其他指标评价等级均为Ⅱ级；状态指标下，植被覆盖率(C

)的评价等级为Ⅰ级，表明该煤矿区植被覆盖率高，尾矿库排洪排渗措施(C

)的评价等级为Ⅲ级，已经达到了不安全的等级，其他指标的评价等级均为Ⅱ级；在响应指标下废弃物综合利用率(C

)以及科研投入增长率(C

)为Ⅱ级，环保投资增长率(C

)为Ⅲ级，其他指标评价等级均为Ⅰ级。 [结论

]

2017—2021年该井工煤矿区生态安全响应力度明显增强，但是生态压力以及目前的状态仍然严峻，应采取针对性地保护措施，从而维护当地的生态安全。

Abstract

[Objective] The ecological security situation of a underground coal mining area in Datong City

Shanxi Province was comprehensively evaluated in order to provide a scientific basis for the ecological protection of the underground coal mining area. [Methods] Based on various indicators from the mining area from 2017 to 2021

an ecological security evaluation index system was constructed based on the three aspects of the PSR model (pressure

state

and response). The combined weight coefficient was determined by the cooperative game method

and the extension cloud model was used to analyze the ecological security situation of the mining area. [Results] Under the pressure index

the evaluation grade of natural population growth rate (C2) was level Ⅲ

indicating that the birth rate and death rate were not evenly distributed

and the evaluation grades of other indicators were all at level Ⅱ. Under the state index

the evaluation grade of vegetation coverage rate (C8) was at level Ⅰ

indicating that the coal mine area had a high vegetation coverage rate. The evaluation grade of tailings pond drainage measures (C9) was at level Ⅲ

having reached the unsafe level. The evaluation grades of other indicators were at level Ⅱ. Under the response indicators

the comprehensive utilization rate of waste (C15) and the growth rate of scientific research investment (C20) were at level Ⅱ. The growth rate of environmental protection investment (C19) was at level Ⅲ

and the evaluation grades of other indicators were at level Ⅰ. [Conclusion] From 2017 to 2021

the response to ecological security of this underground coal mining area had significantly enhanced

but the ecological pressure and the current state were still severe. Targeted protection measures should be taken to maintain the local ecological security.
