运用熵值法,根据生态城市的内涵,从经济建设、社会建设和环境建设三个方面对徐州市2001—2008年的生态城市建设进行了评价。结果发现,徐州市生态城市建设质量在逐年提高的同时存在着发展动力不足的问题。针对该问题,指出行政推动力、经济推动力、城市经济组织与居民推动力、资源与环境约束力是解决徐州市生态城市建设可持续发展动力不足的关键。 相似文献

生态足迹理论是一种定量测度区域可持续发展状态的有效方法。以皖南丘陵山区池州市为例,对其1996-2004年生态足迹和生态承载力进行了计算和分析。结果显示,池州市历年的人均生态足迹不断增加,9年时间增加了37.85%,而人均生态承载力却减少了5.49%。该地区历年人均生态足迹均出现赤字,而且呈增长的趋势;自然资源的利用效率不高以及自然资源供需的非均衡性增长导致生态赤字的出现和持续增长;目前池州市的发展模式已超出了自然生态系统的承载能力,处在不可持续的发展状态,并提出了相应的对策和措施。 相似文献

区域生态安全格局构建是化解生态保护与经济发展之间矛盾冲突的有效途径,进行区域生态安全格局构建研究具有重要理论和现实意义。以位于西南丘陵地区的广安市小井乡为研究区,采用最小累积阻力模型(MCR)对丘陵区生态安全格局构建进行了研究,构建了由9个生态源、18个生态节点和19条生态廊道组成的“点—线—面”结合的丘陵区生态安全格局,在此基础上划分出生态核心区、生态缓冲区、农业耕作区、人类活动区共4个生态功能区,并提出相应的生态安全管控措施,以期为区域制定生态环境管理和生态风险防控措施提供科学依据,同时也为丘陵地区开展生态安全格局构建提供参考。 相似文献

选取美丽中国建设领域的常规性、普适性指标,通过与地区生产总值(GDP)排名前10位的经济发达省(市)对比以及广东省内21个地市美丽建设进程评估,科学评判广东省美丽建设的基础状况和当前进展。结果表明,广东省美丽建设进程成效显著,在经济发达省(市)中排名第3位,但水体洁净、海清岸绿和人居整洁等领域仍需进一步强化;省内美丽建设进程存在两极分化态势,珠三角美丽建设进程总体高于粤东、粤西、粤北,东莞、佛山、中山和湛江美丽建设进程缓慢。 相似文献

The problem of municipal solid waste has remained intractable in Nigeria despite the state’s central role in municipal solid waste management (MSWM). Policy and reforms of the MSWM system have invariably excluded the informal economy, with this exclusion frequently reinforced by uncritical implementation of neo-liberal development policies. Yet, the informal economy fortuitously remains active in solid waste collection, recycling, and disposal. This article is the aggregate outcome of an 8-year multi-stakeholder engagement in MSWM in Nigerian cities. It draws on insights from first-hand qualitative engagement with informal waste workers, interviews with key stakeholders, policy documents, and relevant literature to situate the Nigerian informal waste economy within current international development discourse. While highlighting the implications of social acceptance and inclusion of the waste economy in post-2015 MSWM and development policy, the study notes the lack of an articulate policy on MSWM in Nigeria and canvasses a specific policy to integrate the ubiquitous informal waste economy in MSWM. The paper suggests that inclusion per sé is central to the sustainable development goals (SDGs), and argues that an inclusive MSWM policy in Nigeria is desirable as it maps onto the SDGs which aim to improve lives in the post-2015 development era. 相似文献

Managing municipal solid waste is a pressing environmental and political concern for Canadian municipalities who bear the primary responsibility for waste management (WM). In 2015, Metro Vancouver’s (MV’s) plans to expand their capacity to expand their WM capacity with energy-from-waste technology was abandoned, despite shrinking landfill space and persistent public opposition to new landfills. Using Bulkeley et al.’s [(2005). Governing municipal waste: towards a new analytical framework. Journal of Environmental Policy and Planning, 7(1), 1–23. doi:10.1080/15239080500251700] ‘modes of governing framework’, we analyse MV’s failed attempt to expand their energy-from-waste capacity to better understand the challenges associated with governing WM in Canada. We argue that a history of downloading responsibility for WM to municipalities, regional districts, and industry has fragmented WM governance, posing a challenge for developing new waste infrastructure. We find that this localization of responsibility is incompatible with contemporary WM challenges. The scalar mismatch between waste’s material impacts and the scale at which waste is managed has resulted in co-dependence and conflict between putatively independent municipalities, regional districts, and private companies. This inhibits higher-level WM coordination while the autonomy of individual municipalities is simultaneously undermined. 相似文献

In this paper, we divide the communities in Central China into four groups, namely ecological high-poverty communities, non-ecological high-poverty communities, sustainable communities and non-ecological low-poverty communities. We use 2000 and 2006 data for 498 counties to conduct analysis and comparison between sustainable and unsustainable communities in order to define determinants of the development pathways to sustainable communities. The comparison of the variable means between the groups of ecological high-poverty communities and non-ecological high-poverty communities in 2006 indicates that there is no significant difference in the dimensions related to economy, society and environment, with the exception of average output value per industrial enterprise. The non-ecological low-poverty communities are more likely to have a higher proportion of secondary industry, higher total industrial output value, higher average output value per industrial enterprise and higher intensity of infrastructure construction, compared to the sustainable communities. The factors that determine whether the communities will choose the pathway to sustainable communities are found to be landscape, social conditions of secondary industry and agriculture and economic development level. Hence, the policies that aim at promoting sustainability for the unsustainable communities will have to focus on different strategies and actions for non-ecological high-poverty and non-ecological low-poverty communities. 相似文献
