关于工厂企业绿地建设的探讨：以宝钢为例

生态园林是现代城市绿化发展的趋势和方向。对于污染较为集中的工厂企业来主，绿地建设是环境保护的重要方面。而发展生态园林，走绿地的生态建设道路已成为工厂企业发化的有效途径。本文从生态园林的指导思想出发，结合宝钢的绿化实例，探讨了工厂企业在绿地建设方面的若干问题。     

Parental perception of social risk and of positive potentiality of outdoor autonomy for children: The development of two instruments

An important factor that limits children's autonomy outdoors is parental perception of social danger and traffic danger. To obtain quantitative instruments for these dimensions, this work aimed to explore the validity and reliability of three scales. Two of them describe, respectively, problematic aspects of the area of residence linked to traffic and situations of social degradation that could constitute risk factors for the child's psychological and physical safety (Traffic Danger Perception Scale, Social Danger Perception Scale). The third scale investigates parental perception of the positive potentiality of outdoor autonomy for children's maturation and growth. Interviews were conducted with 377 mothers of children between 8 and 10 years of age residing in six different areas in Italy. The results indicated weak reliability of the Traffic Danger Perception Scale, which requires further investigation, and they confirmed the reliability and the construct validity of the Social Danger Perception Scale and the Perception of Positive Potentiality of Outdoor Autonomy for Children Scale. The perception of social danger was higher in mothers who live in larger urban contexts and who have more personal fear of crime and a lower sense of community. The positive perception of children's autonomy of movement was higher among mothers who live in greener areas, who have a greater sense of community and who have more neighbourhood relations.

The Social Meaning of Carbon Dioxide Emission Trading Institutional Capacity Building for a Green Market in Costa Rica

Forests offer good possibilities for the sequestration of carbon dioxide. This service can be commodified by the introduction of carbon (dioxide) credits, which can be traded on a carbon market. The premise of this paper is that the traditional economic view on the construction of these carbon markets is a too simplistic one, particularly, because it neglects the social meaning of a carbon market for developing countries. From their viewpoint as suppliers of carbon credits such a market has a broader meaning. It must be seen as a social mechanism for improving both the living conditions of local people and a more encompassing improvement of the environment than climate as such. What initially might be labelled as a carbon market might better be understood as a more encompassing 'green market'. The agreement between Costa Rica and Norway, officially known as the Reforestation Conservation Activities Implemented Jointly Project (RFCAIJP) represents a clear example of a green market. In this paper, we study the development, characteristics and benefits of that market, asking the question what lessons can be learned from this first practical experiences. More specifically we focus on the conditions that have made this type of agreement successful.     

Research on challenges and strategies for China’s green economy development

The last 20 years have been the fastest economic developing period of China,and China has made great economic achievements through undertaking international industrial transfer.However,undertaking international industrial transfer has brought about severe environmental problems to China and the process of undertaking international industry transfer is also a process of undertaking international transfer of natural resource consumption and environmental pollution.Nowadays,China has the heaviest ecological burden and highest environmental risk in the world,and is gradually losing international competitive advantages among traditional industries.China is facing unprecedented pressure of economic transformation.Besides the advantages like huge domestic demands and abundant civil capital,China faces more challenges in its green economy development.First,China is still in the middle of industrialization and urbanization processes,hence the huge demands for traditional industries will only last 10-15 more years.Meanwhile,China lacks core technologies for transforming traditional industries,which means these industries will have high shut-down risks.Second,the domestic market share for new green industries is limited,since the market is dominated by traditional energy industries.Third,the value of land,water,mineral,and other natural resources is extremely underestimated because the environmental cost is excluded from the enterprises’cost-benefit calculation.China should foster and expand green industries based on domestic demands,and then strive for competitive advantages in the international market in the future.Therefore,China should focus on the following four points in order to promote green industry development:establishing a forced-upgrading-mechanism for traditional industries,an incentive-development-mechanism for new green industries and a TFP-based(total factor productivity based)economic development evaluation system;promoting the integration of new-type urbanization,new emerging industries,and new employments;taking the model of"technology innovating-patent formulating-standard establishing-market guiding"to enhance the global competitiveness of China’s new emerging industries;and building green consumption patterns in the whole society.

The overlooked role of New York City urban yards in mitigating and adapting to climate change

There is a dearth of research focusing on the role that urban residential open space plays in climate change adaptation, despite evidence suggesting that environmental benefits accrue when even small pockets of open space are made permeable and vegetated. In densely built New York City, there are 21,448?ha (53,000 acres) of such land. One city block with adjoining contiguous open space was investigated to quantify its existing environmental value and also its potential to provide enhanced services through redesign. The study block's open space was found to be 35% permeable and planted with 96 trees, storing 45,359?kg (100,000?lb) of carbon. Simulations conducted using the United States Environmental Protection Agency Stormwater Management Model contrasting normal, light, and heavy precipitation years suggested that increases in annual precipitation could be fully mitigated by reducing impervious surface cover by 25%. The preservation of the existing vegetated residential urban open space and the conversion of paved surfaces to a pervious condition both appear to be effective strategies for enhancing the city's ability to adapt to and mitigate for climate change.     

环境科技创新在绿色经济发展中的应用与实践研究

在雾霾天气越来越严重、环境污染日益恶化的背景下,环境的污染问题明显突出,也成为经济发展的一大障碍。为此,绿色经济发展得到更多人的认识和赞同。人们在发展经济的同时,重视绿色经济的发展,同时更重视环境科技创新在绿色经济发展中的应用。绿色文明是追求人类和自然界的和谐统一,环境保护与经济发展的协调发展。它需要对绿色资源的可持续利用,资源利用不能超过替代资源的发展速度;污染排放量不能超过自净系统的自然规律,科学合理地利用资源。科技创新、绿色文明符合中国当前可持续发展的总体要求,是发展绿色循环经济的思想基础。     

考虑交叉口影响的城市路网能源消耗优化模型研究

为了更精确地反映城市路网交通能耗实际情况,将微观层面的交叉口交通运行与宏观层面的交通网络能源消耗优化结合在一起进行研究,考虑信号控制优化对路网能源消耗的影响,从而实现优化微观的信号控制参数,对宏观的路网能源消耗进行控制。在分析无信号控制交叉口冲突类型的基础上,建立了不同冲突类型下的饱和流率模型,结合排队论理论求解无信号控制交叉口的逗留时间。同时,结合车辆在信号控制交叉口的加减速行为,建立信号控制交叉口的逗留时间模型。同理对信号和无信号控制交叉口的能源消耗量进行建模。综合信号控制和无信号控制交叉口的逗留时间和能源消耗模型,建立路网总能源消耗优化模型,运用Frank-Wolf算法对非线性规划问题进行求解。结合路网各项指标对模型进行分析。结果显示,研究方法相对于传统的定时控制和时间最优信号配时方法均有优势,通过算例应用证明了方法的有效性。
