| 摘 要： | 为探究长山群岛人地关系变化特征以及人类活动对海岛资源环境的影响,利用改进能值生态足迹模型,分析了1996—2016年长山群岛人地关系供需平衡变化情况,并利用脱钩效应模型探讨了海岛经济发展与能值生态足迹之间的关系。结果表明:(1)经济发展速度和海岛居民生活水平的提高使长山群岛能值生态足迹增长,经济发展和城镇扩张导致能值生态承载力不断下降;(2)长山群岛人地关系始终处于生态赤字状态并呈扩大趋势,但各账户生态赤字表征涵义不同,应区别对待;(3)长山群岛能值生态足迹与GDP之间经历了"扩张连接-弱脱钩-扩张连接-弱脱钩-强脱钩"的转变过程,经济发展速度、产业结构和增长方式是脱钩状态变化的重要因素。(4)随着产业重心的转移,长山群岛能值生态足迹的影响从海洋转向岛陆。

| Abstract: | The purpose of this study is to investigate the modification characteristics of the island man-land relationship and the influences of human activities on the island resources and environments in 1996-2016 of Changshan Archipelago. We analyzed the changes of balance between supply of resource environment and demand of human by the improved emergy ecological footprint model. We also examined the relationship between the development of coastal economy and emergy ecological footprint by the decoupling elasticity equation utilizing available statistical data of Changshan Archipelago from 1996 to 2016. The results showed that:(1) the rapid development of economy and the improvement of living standards promoted the swift growth of emergy ecological footprint in Changshan Archipelago. The economic development and urban expansion led to the occupation of land resources and destruction of environment, which reduced the ecological carrying capacity. (2) The overexploitation of marine fishery resources and the growth of fossil energy consumption made the relationship between human and environment in Changshan Archipelago to remain in the state of ecological deficit and show a trend of expansion. Various ecological footprint accounts denoted different meanings that required differential treatments in accordance with specific conditions. (3) The decoupling effect between emergy ecological footprint and GDP in Changshan Archipelago mainly went through the transition process successively by expansion connection, weak decoupling, expansion connection, weak decoupling, and strong decoupling. The speed of economic development, industrial structure, and economic growth pattern were important factors influencing shift of the decoupling between economic development and emergy ecological footprint. (4) The emergy ecological footprint transferred its influence to the island from the ocean. |
