Local hegemonies resisting a green shift and what to do about it: the introduction of a regional park in southern Norway

In the Lister region in the southern part of Norway, attempts are currently being made to facilitate for a green shift. The paper discusses two different approaches towards such a challenge. The first is procedural, where success or failure hinges on the methods applied in the effort to convince locals to incorporate climate considerations. The alternative is to reflect upon how a green ideology blends into pre-existing ideological elements in the region. It is claimed that an important reason for the failure so far to place the environment at the core of regional development, is that too much emphasis has been put on the first approach, on procedure and dialogue, whereas few efforts have been made to understand the structure of the discursive terrain in the region. What prevents a green shift has less to do with methods and is more connected to the dominance of a logic of economic growth and the fact that locals are confident that nature is already dealt with in a sensible manner. The conclusion is that we need to understand what people are concerned about and what prevents them to change, before we start telling them how to think and do development.     

内窥镜检查在电站锅炉内部检验中的应用

System dynamics research of non-adaptive evacuation psychology in toxic gas leakage emergencies of chemical park

Chemical industry park plays an important role in optimizing the allocation of resources, but an emergency may make a great deal of personnel casualty and property loss. Many casualties are not the result of accidents but are caused by extreme behavior because of the non-adaptive psychology of the evacuees. Panic is one of the non-adaptive psychological behaviors during an evacuation, which is influenced by a variety of factors. Based on the consideration of the disaster environment and the evolution of crowd emotion, a system dynamics model of panic spread is established by using Anylogic software, and simulation experiments are carried out for different disaster severity, visibility, and groups. The results show that the number of people with severe panic increase when visibility decreases or disaster diffuses. Besides, the appropriate proportion of groups can effectively reduce the cooling time of crowd and ease the fears. However, continue to increase the number of groups has no significant effect on the panic control. This work can provide some reasonable guidance for regional emergency evacuation in chemical park.     

上海市公园绿地常见落叶树木叶片汞浓度时空特征及环境意义

植物叶片汞浓度与大气气态单质汞(GEM/Hg0)浓度的线性关系表明叶片汞浓度大小可用于指示植物生长区内GEM浓度的高低水平.通过分析上海市绿地公园(25座)中常见落叶树木樱花、水杉、法桐叶片汞浓度的时空变化特征,探究区域内GEM含量水平及分布特征.2017年5—10月对7座公园中这3种树木叶汞浓度进行连续监测,结果显示叶汞浓度与叶片生长时间呈显著线性正相关关系(P<0.01),表明叶片在生长期内不断吸收累积大气汞.而且在生长期内,3种树木叶汞浓度日累积速率(g·kg^-1·d^-1)具有相似的变化趋势,意味着不同树木叶汞的累积对外界环境的响应可能是一致的,除树种差异外.同年11月初,25座公园(包含上述7座)中樱花、水杉、法桐衰老叶片叶汞浓度为(54.2±12,31.8—76.7)μg·kg^-1、(42.0±9,23.5—67.9)μg·kg^-1、(36.1±11,21.4—60.3)μg·kg^-1(平均值,范围),有显著的种间差异(P<0.01),而在中心城区和郊区间无显著差异(P>0.05).空间插值分析结果初步表明衰老叶片叶汞浓度的空间梯度差异不大,且高值区域没有完全重合.这表明了利用衰老叶片叶汞浓度反映区域GEM浓度整体水平空间分布规律存在一定的不确定性,仍需进一步深入研究.

工业园区开展环保管家服务的意义和途径

环保是我国在发展中较为重视的一个工作内容,为了能够顺利地做好城市环保工作,在2016年提出了"环保管家"这个环保概念,通过这个理念推动环保服务业的发展。但是由于该理念提出的时间尚短,所以在实施阶段出现了较多的阻力,导致环保管家并没能实现方案提出的预想效果。鉴于环保管家对工业园区工作的重要性,本文将分析环保管家在工业园区开展的意义以及途径,希望能对相关从业人员的工作有所启发。     

Technological innovation paths toward green industry in China

With the environmental carrying capacity reaching its limits and the decreasing margin benefits of traditional production factors, the green transformation and green development through technological innovations has been a major direction for the future development of Chinese industries. However, the characteristics and heterogeneities of various types of industries call for different approaches regarding technological innovations. How to choose the most effective mode of technological innovation according to the characteristics of a certain industry has been a key issue. This paper measures the green total factor productivity of 32 industrial trades using the Slacks Based Measure(SBM)-DDF method. The effects of three innovation modes in the green transformation of industrial industry, including the independent innovation(Ⅱ), the technology introduction(TI), and the government support(GS), are empirically analyzed based on industry heterogeneity. Results indicate that the green total factor productivities of different industries show significant differences if taking into account the energy input and the undesirable output of pollutant emissions. The green total factor productivities of traditional high input,high pollution, and high energy consumption industrial trades were significantly lower than those with obvious green features. The year of 2009 is a leap year for the industrial green transformation in China. For resource-intensive industries, the II and the GS are the important ways to achieve green transformation. For labor-intensive industries, the TI is the best path to achieve green transformation, while for technology-intensive industries, the II is the primary driving force for the promotion of green developments. In addition, the innovation-compensating effect of the current Chinese environmental regulations to the resource-intensive industries has been revealed. Improving the overall scale and the industrial concentration of the industries is also beneficial for the green transformation of the industries.     

基于循环经济,探索园区污水处理新思路

为响应国家节能减排和循环经济的理念,本文提出一种新的园区污水处理方式-以污治污:利用企业A废水中的碱性物质与消耗企业B废水中的氢离子,再向废水中投加石灰石去除多余的氢离子,投加液碱去除废水中的铜离子和锌离子。优化后的废水处理方式可减少盐酸、石灰石的使用量,从源头上减少了资源的浪费和排入外环境的污染物,对社会发展和生态环境均具有明显的正效益。
