【摘要】：理解城市擴(kuò)展模式與生態(tài)足跡動(dòng)態(tài)之間的關(guān)系是區(qū)域可持續(xù)性研究的重要內(nèi)容,對(duì)實(shí)現(xiàn)城市可持續(xù)發(fā)展具有重要指導(dǎo)意義。然而,目前對(duì)這二者關(guān)系探索的實(shí)證研究較少。以山東半島城市群為例,掌握其2000—2010年的城市擴(kuò)展模式與生態(tài)足跡動(dòng)態(tài)特征,并探索二者之間的關(guān)系。采用景觀擴(kuò)展指數(shù)和生態(tài)足跡模型對(duì)研究區(qū)的城市擴(kuò)展模式和生態(tài)足跡動(dòng)態(tài)進(jìn)行計(jì)算。在此基礎(chǔ)上,將該區(qū)44個(gè)縣劃分為4種類(lèi)型,用相關(guān)分析法對(duì)城市擴(kuò)展模式和生態(tài)足跡動(dòng)態(tài)的關(guān)系進(jìn)行探索。結(jié)果表明,2000—2010年山東半島城市群的城市用地面積增量加了1.2×10~5hm~2,增幅為19.4%。44個(gè)縣均體現(xiàn)出邊緣型擴(kuò)展面積最大,生態(tài)赤字增加的特點(diǎn),平均赤字增量為1.26 hm~2/人。墾利等27個(gè)縣的外延式擴(kuò)展面積與生態(tài)赤字增加量存在較顯著的正相關(guān)關(guān)系,在濟(jì)陽(yáng)等17個(gè)縣中,二者未呈現(xiàn)出相關(guān)關(guān)系。建議墾利、淄博和青島等地區(qū)在未來(lái)城市發(fā)展中,控制飛地型和邊緣型擴(kuò)展面積總量,發(fā)展清潔能源,遏制化石能源足跡的增長(zhǎng)趨勢(shì)。
[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.
