基于生态足迹模型研究了淮海经济区1986—2008年生态足迹(EFs)的年际变化及其空间差异,并对20个成员市的生态可持续性进行了评价。研究表明,区域人均生态足迹呈现快速增长趋势,年均增幅达5.74%。2008年,处在前4位的依次为莱芜市(9.143 6... 基于生态足迹模型研究了淮海经济区1986—2008年生态足迹(EFs)的年际变化及其空间差异,并对20个成员市的生态可持续性进行了评价。研究表明,区域人均生态足迹呈现快速增长趋势,年均增幅达5.74%。2008年,处在前4位的依次为莱芜市(9.143 6hm2),枣庄市(6.340 4hm2),淮北市(6.185 2hm2),济宁市(5.004 9hm2);后4位的分别是阜阳市(1.038 5hm2),周口市(1.122 1hm2),宿迁市(1.209 7hm2),开封市(1.319 5hm2)。各成员市之间存在明显差异,最高者与最低者相差近8倍,其中能源用地是导致生态足迹空间差异的最主要因子。经济区人均生态承载力(ECs)表现为稳中有降,但各成员市之间空间差异程度不大,基本在0.4~0.7hm2之间变化。由此,淮海经济区生态供需状况由1986—1988年的较小盈余,1989年以后逐年出现生态赤字,到2008年人均赤字(EDS)达1.692 1hm2,年均增长29.08%,显然现有生态承载力已不足以支持其生态足迹需求,很大程度上需依靠消耗自然资本存量来弥补生态赤字差额,这种发展模式对自身生态经济系统安全构成了潜在威胁。根据生态可持续评价结果,各成员市的生态可持续指数(IES)普遍偏低,半数以上的城市处在"中度不可持续类"发展状态。其中,莱芜、枣庄、淮北、济宁、泰安、徐州、日照等7市已进入"强不可持续类"城市。最后,从区域科学发展的角度,提出了增强区域可持续发展能力的对策和建议。 展开更多

Somalis Diasporic Transnational Life--From Placelessness to Placeness in Finnish Urban Environment

Then they were the first large refugee group in Finland. They have got integration problems with Finnish society and from that perspective the author started to doubt that whether migrants adopted the same kinds of relationship with the local places and which kind of influence it would have on their integration. The author's aim for this study has been to explore their sense of belonging from transnational family and geographical perspectives. Relph argued that placelessness could be created either by individual itself or urban planning. With the content analyses the author analyzed 50 questions from seven respondents. The questionnaire includes the part of transnational contact keeping among kin members of transnational family, migration and respondents' sense toward urban surrounding where they lives. Emotional ties play a maior role in Finnish Somalis' diasporic life. Emotions intertwine around their life as members of transnational family and toward sense of place. Transnational family affects their perspectives toward western society and urban places. Placelessness is the first step toward integration and positive sense of place. With the integration placelessness turns to placeness. 展开更多
