长江经济带经济演进的时空分析

长江经济带横跨我国东中西部,与沿海经济带共同构成我国国土开发和经济建设的“T”字形宏观格局,是全国经济联系的中心区域,在我国经济发展中具有极其重要的战略地位。改革开放以来,我国率先实施了沿海经济发展战略,地处我国沿海经济带上的长江三角洲、珠江三角洲和环渤海地区得到了超常规发展,带动了全国经济的繁荣,而作为我国另一条发展主轴线的长江沿岸地区,区域发展战略及相关政策的提出则相对较晚。通过对长江经济带的时空分析,选择1992~2010年作为时间序列,以长江经济带作为空间序列,运用定性与定量相结合的手段,在概括长江经济带整体经济发展情况的基础上,分析长江经济带空间分异的变化过程,以期对长江经济带的发展提供可行性的线索和建议

Environmental and economic aspects of production and utilization of RDF as alternative fuel in cement plants: A case study of Metro Vancouver Waste Management

Municipal solid waste (MSW) disposal and management is one of the most significant challenges faced by urban communities around the world. Municipal solid waste management (MSWM) over the years has utilized many sophisticated technologies and smart strategies. Municipalities worldwide have pursued numerous initiatives to reduce the environmental burden of the MSW treatment strategies. One of the most beneficial MSWM strategies is the thermal treatment or energy recovery to obtain cleaner renewable energy from waste. Among many waste-to-energy strategies, refuse-derived fuel (RDF) is a solid recovered fuel that can be used as a substitute for conventional fossil fuel. The scope of this study is to investigate the feasibility of RDF production with MSW generated in Metro Vancouver, for co-processing in two cement kilns in the region. This study investigates environmental impacts and benefits and economic costs and profits of RDF production. In addition, RDF utilization as an alternative fuel in cement kilns has been assessed. Cement manufacturing has been selected as one of the most environmentally challenged industries and as a potential destination for RDF to replace a portion of conventional fossil fuels with less energy-intensive fuel. A comprehensive environmental assessment is conducted using a life cycle assessment (LCA) approach. In addition, cost–benefit analysis (CBA) has been carried out to study the economic factors. This research confirmed that RDF production and use in cement kilns can be environmentally and economically viable solution for Metro Vancouver.     

乡镇经济生态化与生态环境协调发展研究——以浙江省丽水市为例

丽水市乡镇工业崛起迅速,乡镇经济发展成绩明显,但经济增长方式仍以粗放型为主,环境污染出现了蔓延。技术落后、自主创新能力不足,资金短缺、融资困难,行政生态环境有待完善三方面因素阻碍了丽水市乡镇经济生态化建设。为了促进乡镇经济生态化与生态环境协调发展,针对上述问题提出了以优化产业结构、完善金融服务、加快服务型政府建设为基础,以循环经济、特色经济、生态旅游等生态经济化为发展模式,以生态资源有偿使用、生态环境补偿机制为保障的对策。     

Smart Growth and Sustainable Development: Challenges,solutions and policy directions

In this paper, we focus on the issues related to development densities that emerged from our study of sprawl and development issues in three regions of British Columbia, Canada. We chose to focus on this aspect of the Smart Growth agenda because, while many of its other elements enjoy wide support across social interests, the goal of achieving a higher density urban fabric is highly controversial. We proceeded by collecting data on development densities and 13 indicators of community sustainability in 26 municipalities. The results suggest that the density of communities is associated with efficiencies in infrastructure and with reduced automobile dependence, with the ecological and economic implications which flow from that. However, it does not necessarily correlate with greater affordability of housing or more access to green space. In fact, if anything, we discovered a negative relationship between housing affordability and green space per capita and higher land-use densities. In a second stage of the research, we conducted a qualitative analysis of a subset of six municipalities and identified key policy issues for moving ahead with the Smart Growth agenda. The paper concludes with a discussion of the policy issues that emerged from these case studies.

废显像管玻璃循环经济模式系统分析研究

近年来,我国CRT显像管制造行业迅速发展,但制造显像管所需的大量优质矿石和化工原料的开采和合成过程却破坏了自然生态环境,还造成环境污染.同时,大量被淘汰和不合格的显像管被简单处理,造成巨大的优质资源浪费.采用系统分析的方法,对废显像管玻璃再利用进行环境分析,从而找出适合我国的废显像管玻璃循环经济模式,并使用模糊综合评价对废显像管玻璃循环经济效益的综合评价方式进行了探讨.     

从清洁生产到循环经济

清洁生产和循环经济是20世纪90年代以来在我国引人注目的两项实践。正确认识、积极推进清洁生产和循环经济,对于转变我国经济增长方式与发展模式、促进可持续发展具有重要意义。在将资源环境要素纳入经济系统内部,转变经济增长方式,促进资源环境和经济结合一体化发展模式的概念意义下,本文从宏观历史层面阐述了我国清洁生产和循环经济的发展过程、必然趋势及其长期曲折、交错推进的过程特征。分析了以废物循环作为循环经济的认识和实践误区,提出了以清洁生产为基础推进产业生态化,结合强化末端管制,以及围绕建立“绿色”市场进行制度创新为基本内容的发展我国循环经济的建议。     

中国收入差距与环境质量关系的实证检验--基于对环境库兹涅茨曲线的扩展

在对环境库兹涅茨曲线（EKC）假说扩展的基础上,分析和验证了收入差距与环境质量之间的关系。应用联合国统计司公布的中国1986—2002年度二氧化碳排放总量数据,通过计量模型论证收入差距与环境质量之间的假设。结果发现,收入差距扩大会刺激二氧化碳排放,收入差距越大这种影响的效果就会越恶劣。而且收入差距因素还会通过作用于经济增长,促使经济增长对环境的污染程度加强。延迟转折点的到来。因此,我国目前在促进经济增长的同时,要以提高社会整体福利为目的,缩小居民收入差距,这将有利于环境质量的改善和提高。     

Elements of a cost-benefit analysis for improving salmonid spawning habitat in the River Wye

Contingent valuation methods were used to derive an economic value for salmonid spawning habitat restoration. Anglers' willingness to pay for such restoration and farmers' willingness to accept compensation for lost productivity due to the restoration were investigated using questionnaire and face-to-face surveys, respectively. These elements were combined with the Wye Habitat Improvement Project (WHIP) budget into a cost-benefit analysis (CBA) based upon direct use values only. The CBA assumed that the WHIP will improve salmonid stock. Different levels of investment were considered and the CBA gave a positive net present value indicating an economically viable project and benefit-to-cost ratios greater than one for minor projects. However, the number of anglers using the Wye would need to double or triple in order to justify the full WHIP budget. Management of an environmental resource must consider users' and stakeholders' needs and opinions. It was found that anglers on the Wye value habitat/scenery in its own right and that this played an important part in the activity. Farmers' agreement regarding involvement in such projects was more likely to be determined by their political and ethical views than receiving an economic compensation.
