摘要
核算自然资本是区域可持续发展领域的核心议题。利用改进后的三维生态足迹模型,对甘肃省1999—2016年自然资本利用动态演变过程进行定量分析,并采用偏最小二乘法分析其驱动因素。结果表明:甘肃省人均生态足迹呈先增后减的变化趋势,人均生态承载力相对稳定,人均生态赤字与人均生态足迹变化趋势一致;足迹深度和人均足迹广度表明资本流量无法满足人类对自然资源的需求,对资本存量的消耗成为社会经济发展的常态;从地类组分构成来看,化石能源用地、耕地和水域是资本存量消耗的主要方式,林地是资本流量占用的主要方式,草地和建筑用地的自然资本利用经历了从资本流量过渡为资本存量的过程;环境污染、能源消耗等是导致甘肃省自然资本利用增加的主要因素,而生态建设、科技进步、土地利用结构改善和环境治理在一定程度上缓解了自然资本利用压力。
Accounting for natural capital utilization is the core in regional sustainable development.Based on the improved three-dimensional ecological footprint model,we analyzed the changes of natural capital utilization in Gansu Province from 1999 to 2016.The driving factors were analyzed using the method of partial least-squares regression.The ecological footprint per capita of Gansu Province increased first and then decreased.The ecological carrying capacity per capita was relatively stable.The trend of ecological deficit per capita was consistent with that of ecological footprint per capita.The ecological footprint depth and the ecological footprint size per capita indicated that capital flow could not satisfy human demands for natural resources,and that the consumption of capital stock becomes the normal state of social economic development.From the perspective of territorial composition,fossil energy land,cultivated land and waters are the main ways of capital stock consumption.Forest land is the main way of capital flow occupation.The natural capital use of grassland and construction land has undergone a process of transitioning from capital flows to capital stocks.Environmental pollution and energy consumption are the main factors leading to the increases of natural capital utilization in Gansu Province.Ecological construction,scientific and technological progress,land use structure improvement,and environmental governance have alleviated the pressure of natural capital utilization to some extent.
