    摘要:

    [目的] 对山西省矿区自然资本存量进行动态评估,为矿区生态环境保护及生态补偿提供理论依据。[方法] 以矿区自然资本为视角,基于生态足迹与生态承载力核算结果,运用三维生态足迹模型,测算山西省矿区2010—2019年生态足迹深度与足迹广度,借助足迹深度与足迹广度的剪刀差分析其动态演变特征并阐释矿区自然资本存量动态演变的作用机理。[结果] ①山西省矿区人均生态赤字由2010年的4.40 hm2/人增加到2016年的6.31 hm2/人,随之降低到2019年的5.02 hm2/人,生态足迹与生态承载力的差距总体趋于缩小; ②2010—2019年,人均生态足迹广度大致呈递减趋势,由0.63 hm2/人降到0.47 hm2/人,而人均生态足迹深度呈现出先增后减的“倒U”形变化趋势; ③矿区自然资本存量时空动态演化是由煤炭资源禀赋、开采规模、矿区生态供求、生态足迹与承载力以及资本流量、存量的深度、广度等多重因素综合作用的结果。[结论] 山西省矿区生态足迹与承载力差距趋于好转,但生态赤字仍然严重存在。

    Abstract:

    [Objective] The natural capital stocks in Shanxi mining areas were dynamically assessed, in order to provide theoretical basis for the ecological environment protection and ecological compensation for the mining area.[Methods] In terms of natural capital of mining area, and based on the ecological footprint and ecological carrying capacity of the mining area, a three-dimensional ecological footprint model was used to calculate the depth and breadth of the ecological footprint in the Shanxi mining area during 2010-2019. Its dynamic evolution characteristics were further analyzed with the help of the scissors difference between the depth of the footprint and the breadth of the footprint, and then explains the mechanism of the dynamic evolution of the ecological occupation of the mining area.[Results] ① The ecological deficit per capita in Shanxi mining areas increased from 4.40 hm2 in 2010 to 6.31 hm2 in 2016, and then decreased to 5.02 hm2 in 2019. The gap between ecological footprint and ecological carrying capacity tends to narrow overall. ② From 2010 to 2019, the breadth of the per capita ecological footprint generally showed a declining trend, from 0.63 hm2 to 0.47 hm2, and the depth of the per capita ecological footprint showed an inverted U-shaped change trend that first increased and then decreased. ③ The temporal and spatial dynamic evolution of the natural capital stocks for the mining area was the comprehensive effect of multiple factors such as the endowment of coal resources, the scale of mining, the ecological supply and demand of the mining area, the ecological footprint and carrying capacity, the flow of capital, and the depth and breadth of the stock.[Conclusion] The gap between the ecological footprint and carrying capacity in the Shanxi mining area tends to be improved, but the ecological occupation deficit still exists.
