摘    要:生态环境是区域社会经济发展的物质基础和空间载体,对其研究有助于统筹人类社会与生态系统的协调发展。以2006—2016 年舟山市社会经济面板数据为基础,利用三维生态足迹模型探究舟山市自然资本利用演变特征,借助地理探测器揭示自然资本动态变化的驱动机制。结果显示: (1) 研究期内,舟山市自然资本需求大于供给。人均生态足迹上升1.295 hm2·人-1,人均生态承载力增加 0.233 hm2·人-1,表明舟山市自然资本需求不断上升,自然资本供给能力也在不断增强。各县区自然资本供需存在差异,定海的自然资本供应大于需求,普陀、岱山与嵊泗均表现为自然资本需求大于供给。 (2)舟山市对自然资本存量消耗呈缓慢增加趋势,而自然资本流量占用呈波动下降趋势,自然资本利用处于不可持续发展的状态。各县区的自然资本存量消耗呈增加趋势,嵊泗自然资本流量占用逐年下降,普陀与岱山呈倒 U 形增长,而定海则呈波动下降趋势。 (3) 因子探测结果显示,常住人口数、废水排放量是舟山市自然资本演变的主导因素。交互探测结果显示,各影响因素的交互作用均强于单独作用。其中,常住人口疑工业废气产生量和常住人口疑废水排放总量的交互作用对自然资本演变的影响最大。今后舟山市应增强单位土地的生态承载力,提高自然资本的供给能力,并通过合理控制人口数量,推动技术创新,提升资源能源利用效率,积极发展环保产业,降低对自然资本的需求,实现区域可持续发展。

关 键 词:自然资本  三维生态足迹  地理探测器  舟山市

Abstract:Ecological environment is the material basis and spatial carrier of regional social and economic development. Its research is helpful to the coordinated development of human society and ecosystem. Based on the social and economic data from 2006 to 2016, the three-dimensional ecological footprint model was used to explore the utilization of natural capital in Zhoushan city, and the driving mechanism of the dynamic change of natural capital was revealed with the help of geographical detectors. The findings are as follows: (1) During the study period, the demand for natural capital in Zhoushan is greater than the supply. The per capita ecological footprint increased by 1.295 hm2/man-1, while the per capita ecological carrying capaity increased by 0.233 hm2/man-1, indicating that the demand for natural capital in Zhoushan city was rising, while the supply capacity of natural capital was also increasing. There are differences in natural capital supply and demand in different counties. The natural capital supply in Dinghai is greater than the demand, while the natural capital demand in Putuo, Daishan and Shengsi is greater than the supply. (2) The consumption of natural capital stock in Zhoushan city is increasing slowly,while the occupation of natural capital flow is decreasing in a fluctuating trend thus resulting unsustainable development. The consumption of natural capital stock in all counties and districts shows an increasing trend, while the occupancy of natural capital flow in Shengsi decreases year by year. (3) Factor detection results show that the number of permanent residents and the discharge of waste water are the leading factors for the evolution of natural capital in Zhoushan city. The results of interaction detection show that the interaction of factors is stronger than that of any single factor. Among them, the interaction between the permanent population the total wast ewater discharge and the permanent population the amount of industrial waste gas production has the greatest impact on the evolution of natural capital. In the future, Zhoushan city should strengthen the ecological carrying capacity of unit land and improve the supply capacity of natural capital. In addition, measures on reasonably controlling the population, promoting technological innovation should be taken to improve the utilization efficiency of resources and energy, actively developing the environmental protection industry, reducing the demand for natural capital, and realizing sustainable regional development.
Keywords:natural capital  three-dimensional ecological footprint  geographic detector  Zhousha
