城市增长与地球环境的关系

为维持地球健康,减少城市对地球环境的影响,以城市有机体的代谢为分析起点,首先从地球系统科学的视角分析城市增长与有限的地球环境资源的矛盾冲突,进而探讨城市无限增长的一种政治经济根源,在此基础上,思考探索城市环境可持续运行的可能途径.     

Progress in indicators to assess agricultural landscape valuation: how and what is measured at different levels of governance

Landscape is defined by the European Landscape Convention as “an area perceived by people, whose character is the result of the action and interaction of natural and/or human factors”. Many efforts have been devoted in addressing the core concepts on which this definition roots: perception and interaction of men and nature, but when coming to large (continental) scale assessments, the latter prevail on the former.This paper aims at presenting a framework for a measurable landscape awareness indicator as a key link to the public demand for a specific type of landscape: the agricultural landscape. This is a necessary effort to complement more physically based assessments, which include as well the impact of human activities on landscapes.The analysis is carried out at different levels of governance: EU and regional, using an example from the Alentejo region in Portugal and EU wide databases, and addresses conceptual and practical questions: what type of societal landscape awareness can be monitored and by whom (e.g., individuals, specific social groups, society as a whole); what are the landscape dimensions that should be assessed; what are the limitations imposed by data-related constraints. By applying the methodology to build composite indicators to map landscape societal awareness, the paper shows the regional and local meaning of indicator approaches developed at European level, presents developments for downscaling to regional level, while introducing the social component to support sound policy development for European rural landscapes.     

京津冀城市群能源代谢时空特征及优化调控研究

随着中国经济的快速发展,能源消费也快速增长。随着节能减排的压力越来越大,能源的代谢需要根据需求进行更替。论文就京津冀城市群能源代谢时空特征分析并对能量代谢进行优化和调控提出建议。     

Marketing and society: Preface to special section on volunteerism, price assurances, and direct-to-consumer advertising

We discuss the reasons why this call for papers was issued and describe the process of selecting the three articles presented in this special section. We argue that maximizing stakeholder welfare and not just consumption maybe a new goal for marketing that will be consistent with emerging societal trends. Three articles on volunteerism, price assurances, and direct-to-consumer advertising result from our call and are presented in this section. This introduction is an overview of the three articles.     

五黄养阴颗粒治疗2型糖尿病合并脂代谢异常临床研究

目的观察五黄养阴颗粒治疗2型糖尿病合并脂代谢异常的临床疗效。方法选择458例门诊患者随机分为两组,A组给予五黄养阴颗粒,B组给予糖脉康。比较两组患者治疗前后血糖疗效。结果两组患者在0周与8周时空腹血糖值比较,A组患者血糖、糖化血红蛋白、血脂及中医证候疗效指标均优于B组。结论五黄养阴颗粒治疗2型糖尿病合并脂代谢异常的临床疗效可靠,且未发现不良反应。     

药物代谢研究在新药研究中的作用

药物代谢是新药研究的重要环节之一,从药物代谢在新药开发初期寻找具有良好药代性质的候选物、先导物结构改造和结构修饰、硬药和软药的设计方面等,阐述了药物代谢在药物研究中的重要作用。探讨药物代谢研究在新药研究中的作用,将推动新药研究的开展,加速新药研究开发的进程。     

福斯特生态学马克思主义探析

约翰·贝拉米·福斯特是生态学马克思主义的重要思想家和代表人物。福斯特在马尔库塞的制度批判和社会批判、阿格尔的消费异化导致生态危机、奥康纳的双重危机等理论的基础上,通过对马克思主义经典著作的文本解读,运用马克思主义生态唯物主义理论和方法,深刻分析了资本主义与生态矛盾的根本原因,提出了自己的生态学马克思主义思想,同时完成了对马克思主义生态学思想的理论重构。     

我国生态工业园该如何走出困境?

理论是对事物本质的把握,生态工业园区的理论模型是对生态工业园区本真性反映,是对生态工业园区合理运行机制的根本性揭示.其本质性内容是工业园区内的企业完成物质资料的相互交换和循环,即一个企业排放的废弃物能够成为另一个企业的生产原料.该理论模型既做到节约成本,提高企业经济效益,又使废弃物得到最大化利用和充分循环,还减少了对自然环境的污染.就目前而言,我国的生态工业园区创建仍然处于初级阶段,潜在的环境经济效益仍需较长时间的努力和一定资金的投入才能显现.最重要的体现是生态工业园区内的经济发展和生态环境保护并未得到平衡的发展,仍然存在以环境污染为代价的现象.     

城市生态系统代谢分析方法与评价指标研究进展

我国正处于快速城市化进程中,资源的生产与消费支撑着城市经济增长,同时也关系到生态胁迫、环境影响及公众健康等方面的可持续发展,城市代谢系统与此密不可分.本文系统讨论了本研究领域内的最新进展,阐明了物质性代谢与非物质性代谢的内涵与联系,对相关概念、新的研究方法及评价指标进行了总结、比较与探索,以期促进城市生态系统代谢分析的进一步发展和应用.
