| 摘 要： | 基于能值理论,结合生态足迹方法,构建能值生态赤字/盈余、渔业足迹强度(D)、社会发展压力指数(I)和经济协调指数(Q)参数评价海岛可持续性,选取典型海岛城市浙江省舟山市作为案例研究。结果显示:2003—2017年舟山能值足迹、能值承载力均呈上升趋势;人均能值生态足迹共增加15.78 hm2,增幅为63.26%;人均能值承载力增加5.20×102 hm2,增幅为82.86%;其中,化石能源用地能值足迹增加最多,社会经济承载力增加最多,而自然承载力却有所下降。能值生态赤字/盈余和经济协调指数不能完全反映区域可持续性,区域渔业足迹强度的不断增加表明当前的渔业经济模式不满足可持续发展要求,社会发展压力指数增大也进一步表明舟山的发展状况偏离了可持续性的轨道。

| Abstract: | The island sustainability is evaluated by establishing the parameters such as emergetic ecological deficit/surplus, fishery footprint intensity (D), social development pressure index (I) and economic coordination index (Q) based on emergy theory and ecological footprint method. For the case study, Zhoushan of Zhejiang Province, a typical island city, is taken as the example. The results show that from 2003 to 2017 the emergy footprint and the emergy carrying capacity in Zhoushan were all on a rising trend; the emergy ecological footprint per capita increased by 15.78 hm2 with an amplification of 63.26% and the emergy carrying capacity per capita increased by 5.20×102 hm2 with an amplification of 82.86%, of which both the emergy footprint of the land used for fossil energy and the socio-economic carrying capacity increased the most, while the natural carrying capacity decreased. The emergetic ecological deficit/surplus and the economic coordination index cannot fully reflect the regional sustainability. The continuously increasing of the regional fishery footprint intensity indicates that the current fishery economic model doesnot meet the requirements of sustainable development. The increasing of the social development pressure index further indicates that the development status in Zhoushan has deviated from the sustainable track. |
