济宁生态市规划与建设途径

生态市是实现城市社会—经济—自然可持续发展的一种模式和过程。以山东省济宁市为例,提出了济宁生态市建设的战略措施。从资源型城市的产业生态转型、水体和矿山的自然生态修复和孔孟文化的人文生态振兴3方面提出了建设目标;建设框架包括自生型生态环境、竞争型循环经济和共生型和谐社会。主导产业和循环经济建设要促进传统农业和矿山开采型产业向静脉产业、阳光产业、物流产业、文化产业和旅游产业的生态转型;从水资源、水环境、水生态、水景观、水安全和水文化建设几方面提出了水资源保护与水环境治理的综合措施;最后提出了济宁市煤矿塌陷区的生态修复对策和生态文化建设策略。     

生态城市规划需要优先考虑的几个问题

建设生态城市是城市发展的未来方向,而生态城市规划则是生态城市建设的起点,因此在规划中需要优先考虑城市经营成本问题、人力资源转化问题、区域生态安全问题和增长空间控制问题,从而使城市的生态设计建立在理性分析的基础上。     

Embodied energy and emergy evaluation of a typical biodiesel production chain in China

Biodiesel from non-grain feedstock has been considered as one of the proper substitutes for fossil fuels associated with a series of activities emerging in China in order to meet the resource shortage and develop the energy crops. This paper presents an ecological accounting framework based on embodied energy, emergy, and CO₂ emission for the whole production chain of biodiesel made from Jatropha curcas L. (JCL) oil. The energy and materials invested in and CO₂ emission from the whole process, including cropping, transportation, extraction, and production, are accounted and calculated. Also, E_mCO₂, the ratio of real CO₂ released to the emergy-based sustainability indicator per joule biodiesel, is proposed in this paper to present a new goal function for low-carbon system optimization. Finally, the results are compared with those of the bioethanol (wheat) production in Henan Province, China, and bioethanol (corn) production in Italy in view of the indices of embodied energy, emergy and CO₂ emissions and E_mCO₂.     

低碳经济背景下地方政府环境政策执行力调控研究

环境政策执行力与低碳经济发展之间相互促进、相互推动。目前我国已形成较完整的环境政策体系,但在实际执行中并未取得应有的成效。参考国内外已有的地方政府环境政策执行力调控经验,分析环境政策执行力影响因素,从管理体制、诱导制度、监督制度、执行主体自身建设等多个角度提出在低碳经济背景下我国地方政府环境政策执行力调控策略。     

宝鸡市生态城市建设评价

结合生态城市的相关理论和不同学者的研究,遵循生态城市评价指标选择的原则和研究区域的实际情况,从经济、社会和自然三方面建立了宝鸡市生态城市建设的评价指标体系。通过采用熵权法确定各评价指标的权值,对宝鸡市近几年的生态城市建设进行了简要评价。结果表明,2004—2008年宝鸡市的生态城市建设十分成功,但在集中力量建设生态环境的同时,忽略了对城市的经济建设,使宝鸡市的经济结构开始出现不合理现象。建议宝鸡市在大力建设生态城市的同时,要集中力量在经济建设方面,以达到自然、经济与社会和谐发展的目的。

创建新型生态城市的探索--以黄石市为例

现代化城市建设对生态环境提出了新的要求。文章首先阐述了生态城市的内涵和创建生态城市的必要性；然后从主要污染物、主要水体、水土保持和森林覆盖率四个方面，分析了黄石市的生态环境现状；最后以可持续发展和人与自然高度和谐统一为目标，提出了将黄石市创建成为新型生态城市的具体措施。     

浅谈生态市建设的实践与思考--以大庆为例

文章阐述了生态城市建设的起源,大庆市创建生态市的历程。大庆市通过采取编制生态市规划、实施“治水、净气、复草、植树、降噪”五大工程、广泛动员全民参与等措施,于2015年1月成功建设成为黑龙江省首家省级生态市。针对生态市创建工作中的不足,大庆市将在未来做好建立健全推进机制、构建全民参与格局、拓展多元融资渠道三方面工作。对未来生态市建设的必然性进行思考,认为生态市建设作为生态文明建设的有效载体,必将成为城市未来建设和发展的主流。     

Living the green city: Freiburg's Solarsiedlung between narratives and practices of sustainable urban development

The solar settlement (Solarsiedlung) in Freiburg, Germany, has been widely hailed as an eco-city or green city neighbourhood and a blueprint for sustainable urban development. However, as there is a noticeable lack of critical analysis of what constitutes Solarsiedlung as an “eco-city”, this paper studies narratives and practices of sustainable urban development. First, we look at Solarsiedlung as a best-practice model – a narrative that was produced and perpetuated by architects, urban planners, investors and academics celebrating this neighbourhood as a technologically leapfrogging, economically sound and socially integrated project. Second, we explore the everyday practices and lived experience of the residents in Solarsiedlung. Bringing together these two perspectives, we contribute to a more comprehensive understanding and critical reading of the interplay between the ecological, economic and social dimensions of sustainable development as seen from different viewpoints. Findings indicate that Solarsiedlung as a best-practice model is embedded in growth-oriented neoliberal strategies that are in conflict with the everyday practices and lived experience of the residents. Our findings put into question the widely assumed transferability of best-practice models in sustainable urban development.
