摘要: 厘清海岸带自然资本存量消耗和自然资本流量占用情况及其影响因素,能有效缓解海岸带社会经济发展与自然资源、生态环境之间的矛盾,促进区域协调可持续发展。本研究基于二维和三维生态足迹评价模型,分析浙江省海岸带2006—2016年生态足迹时空变化特征,基于足迹深度和足迹广度探究了区域自然资本存量和资本流量占用情况,并利用时空地理加权模型分析其影响因素的时空异质性。结果表明: 研究期间,浙江省海岸带生态危机加深,人均生态赤字平均值为3.5 hm2·cap-1,人均生态赤字上升了15.5%,其中,能源消耗账户对人均生态足迹的贡献率大于生物资源账户;各县区人均生态足迹呈增长趋势,且空间分异显著。浙江省海岸带以消耗自然资本存量为主,且对自然资本流量更新起到较大的抑制作用;2016年,自然资本存量的消耗量是资本流量占有量的14.87倍。城市规模和经济发展水平、人民收入水平对浙江省海岸带各县区生态足迹以正向促进作用为主,渔业生产对生态足迹为负向影响,并有向正向影响作用转换的趋势,3个影响因子的影响机制时空分异性显著。

Abstract: Clarifying the consumption of local natural capital stock and natural capital flow and its influencing factors can help alleviate the tension between the socio-economic development of the coastal zone, natural resources, and the ecological environment, and promote regional coordinated and sustainable development. Based on the two-dimensional and three-dimensional ecological footprint evaluation models, we analyzed the spatial and temporal variations of ecological footprint in the coastal zone of Zhejiang Province from 2006 to 2016, and explored the regional natural capital stock and capital flow occupancy based on footprint depth and footprint width. We analyzed the spatial and temporal heterogeneity of its influencing factors using a geographically and temporally weighted regression model. The results showed that ecological crisis in the coastal zone of Zhejiang Province deepened during the study period. The average per capita ecological deficit was 3.5 hm2·cap-1, and the per capita ecological deficit increased by 15.5%. Among them, the contribution of energy consumption account to the per capita ecological footprint was greater than that of the biological resources account. The per capita ecological footprint of each county showed an increasing trend, with significant spatial variation. The coastal zone of Zhejiang Province mainly consumed the natural capital stock, with a significant inhibitory effect on the renewal of natural capital flows. The consumption of natural capital stock was 14.87 times that of capital flow in 2016. Urban scale, economic development level, and people’s income level had positive impacts on the ecological footprint of coastal counties of Zhejiang Province, while fishery production had negative effect on the ecological footprints, with transition trend to a positive one. The influence mechanism of the three factors had significant spatial and temporal differentiation.
