基于改进三维生态足迹的自然资本动态评估——以南水北调中线工程核心水源地为例

摘  要：
自然资本利用评估一直是可持续发展的核心议题。采用改进后的三维生态足迹模型对南水北调中线工程核心水源地2009—2018年自然资本利用状况进行动态评估。结果表明:人均生态足迹广度呈现出不断增加的趋势,人均生态足迹深度却呈现出不断减小的趋势,说明研究区域资本流量利用不断增加,资本存量消耗不断减少,区域可持续发展能力逐步增强;不同地类自然资本利用存在差异,耕地、牧草地、水域的生态足迹广度与其生态承载力相等,其自然资本流量已被充分占用,但其生态足迹深度呈逐年递减的趋势,说明这3类资本存量消耗不断减少,其生态系统供给压力逐步缓解。

摘  要：
The three-dimensional ecological footprint model is the latest development in the field of sustainability research.Three-dimensional ecological footprint model is used to evaluate the natural capital using of the core water source of the South-to-North Water Transfer Project during 2009 to 2018.The results show that the size of per capital ecological footprint shows an increasing trend,while the depth of per capita ecological footprint shows a decreasing trend.Which shows that the utilization of capital flow is increasing,the consumption of capital stock is decreasing,and the supply pressure of ecosystem is gradually alleviated.There are differences in the utilization of natural capital in different land types.The ecological footprint size of cultivated land,grassland and water area is equal to its ecological carrying capacity.Which shows its natural capital flow has been fully occupied,but its ecological footprint depth is decreasing year by year,and which shows that the consumption of these three types of capital stock is decreasing,and the supply pressure of the ecosystem is gradually relieved.
