【摘要】：理解城市扩展模式与生态足迹动态之间的关系是区域可持续性研究的重要内容,对实现城市可持续发展具有重要指导意义。然而,目前对这二者关系探索的实证研究较少。以山东半岛城市群为例,掌握其2000—2010年的城市扩展模式与生态足迹动态特征,并探索二者之间的关系。采用景观扩展指数和生态足迹模型对研究区的城市扩展模式和生态足迹动态进行计算。在此基础上,将该区44个县划分为4种类型,用相关分析法对城市扩展模式和生态足迹动态的关系进行探索。结果表明,2000—2010年山东半岛城市群的城市用地面积增量加了1.2×10~5hm~2,增幅为19.4%。44个县均体现出边缘型扩展面积最大,生态赤字增加的特点,平均赤字增量为1.26 hm~2/人。垦利等27个县的外延式扩展面积与生态赤字增加量存在较显著的正相关关系,在济阳等17个县中,二者未呈现出相关关系。建议垦利、淄博和青岛等地区在未来城市发展中,控制飞地型和边缘型扩展面积总量,发展清洁能源,遏制化石能源足迹的增长趋势。
[Abstract]:Understanding the relationship between urban expansion model and ecological footprint dynamics is an important part of regional sustainability research and has important guiding significance for the realization of urban sustainable development. However, there are few empirical studies on the relationship between the two. Taking Shandong Peninsula urban agglomeration as an example, the dynamic characteristics of urban expansion model and ecological footprint from 2000 to 2010 are grasped and the relationship between them is explored. The landscape expansion index and ecological footprint model were used to calculate the urban expansion model and ecological footprint dynamics in the study area. On this basis, 44 counties in this area were divided into 4 types, and the relationship between urban expansion model and ecological footprint dynamics was explored by correlation analysis. The results show that the urban land area increment of Shandong Peninsula urban agglomeration increased by 1.2 脳 10 ~ (5) h ~ (-2) from 2000 to 2010, with an increase of 19.4.44 counties showing the characteristics of the largest marginal expansion area and increasing ecological deficit, with an average deficit increment of 1.26 hm~2/. There is a significant positive correlation between the extended area and the increase of ecological deficit in 27 counties such as Kenli, but there is no correlation between them in 17 counties such as Jiyang. It is suggested that in the future urban development in Kenli, Zibo and Qingdao, the total amount of enclave and marginal expansion area should be controlled, clean energy should be developed, and the growth trend of fossil energy footprint should be restrained.
