构建生态环境技术服务体系的基本定位与主要对策

四个方面的情况表明,我国必须高度重视生态环境技术服务体系建设问题:一是随着污染防治攻坚战在向纵深推进过程中,地方政府"不会管"、企业"不会治"的问题比较普遍,且日益突出;二是目前各级生态环境部门,特别是市、县两级生态环境技术支持力量薄弱、专业化能力不足,难以支撑当地政府和企业治理环境污染的技术需求;三是目前的生态环境技术服务市场尚满足不了实际需求;四是无论是从结构还是从作用看,生态环境技术服务体系已成为生态环境治理体系和治理能力的短板。因此,构建生态环境技术服务体系是推进生态环境治理体系和治理能力现代化的重要内容,其作用是,在要求环境责任主体做什么的同时,帮助和指导他们怎么做,解决"不会管"和"不会治"的问题。现阶段,政府推动构建生态环境技术服务体系的重点任务:一是明确职能,系统谋划,做好顶层设计;二是强化相关能力建设;三是建立和完善生态环境标准和重大规划与行动计划的配套技术方案制度;四是培育、壮大和规范生态环境技术服务市场;五是以生态环境科技成果转化为抓手,牵引技术服务体系建设。     

推动生态环境科技成果转化的对策研究

生态环境科技成果转化是打好污染防治攻坚战的关键之举，目前我国生态环境科技成果转化水平较低，还存在着工作体系不完整、供需脱节和缺少有效的对接渠道等问题。本文分析了生态环境科技成果转化的内涵及其特点，并针对现有问题，从建设体制机制和平台、搭建成果转化评价体系、发挥政府和市场双重作用、促进多行业成果融合的角度提出了未来推动生态环境科技成果转化的对策建议。     

Critical success and limiting factors for eco-industrial parks: global trends and Egyptian context

The trend of clustering industries into regional estates or cities was adopted in the mid 1900’s. At present, the number of industrial estates in the world is estimated to be between 12,000 and 20,000 (UNEP, 1997) and this trend is continuing to rise in both developed and developing countries. The implementation of the EIP concept continues to evolve especially with the environmental threats and impact on climate change that industries pose. However, there is not yet a fully developed EIP that is operating; although some successful examples of regional by-product exchanges are functioning ( [Lowe, 2001], [Peck, 2002], [Lowe et?al., 1995] and [Chertow, 2000]). Actually, a significant number of projects have failed or have abandoned the goal of becoming an EIP. Furthermore the current body of knowledge on industrial ecology is not sufficient to provide practical solutions to the obstacles facing EIPs.This paper is based upon the Ph.D. Doctoral thesis research of D. Sakr. It was prepared to examine means to improve the uptake of cleaner production & industrial symbiosis in industrial areas in Middle East & North Africa Region focusing on Egypt as a case study. An extensive literature review was performed on eco-industrial development projects’ experiences around the world, in order to identify the critical driving and limiting factors for EIPs. This paper summarizes the lessons learned from worldwide EIP experiences as a basis for the planning and implementation of future EIPs. The paper reflects as well upon the Egyptian context for the identified EIP success and limiting factors. The identified key success and limiting factors are: the creation of symbiotic relationship, information sharing and awareness, financial benefits, organizational structure, and legal and regulatory framework.     

Developing industrial water reuse synergies in Port Melbourne: cost effectiveness, barriers and opportunities

Urban water scarcity from ongoing drought and an increasing population are driving a range of water saving options to be explored in Melbourne (Australia). This paper assesses the cost effectiveness of five water treatment and industrial reuse options in the Fishermans Bend industrial area at Port Melbourne. In consultation with industrial stakeholders and the local water utility, the study design began by identifying potential water sources and sinks in the area. Treatment technologies for each option - using a combination of membrane bioreactors (MBR) and in some cases reverse osmosis (RO) technologies - were developed. In evaluating the potential for future implementation, the cost effectiveness ($/kiloLitre) was assessed relative to water supply augmentation and water demand management options available in Melbourne. Additionally, the opportunities and barriers for option implementation in Port Melbourne were contrasted with the Kwinana Industrial Area, Western Australia where many regional synergy projects have been undertaken. This research identifies that the future implementation of industrial ecology opportunities requires strong and ongoing stakeholder involvement as described in this paper.     

对《大小兴安岭林区生态保护与经济转型规划》实施后的思考

在国家十二五规划开局之际,二期天保工程启动之时,国家发改委、国务院颁布出台了《大小兴安岭林区生态保护与经济转型规划》,为大小兴安岭林区带来了前所未有的机遇和挑战。《规划》的出台,对于加快推动大小兴安岭林区经济社会发展具有重大的现实意义和深远的历史意义。社会对生态建设的迫切需求,人们对生态改善的迫切渴望,市场对绿色产品、林特产品等需求的不断扩大,维护我国木材安全问题的提出,都为林业和林区的发展带来了机遇。另一方面,稳定粮食生产、经济发展对资源的过度依赖,又给保护生态带来巨大压力。《大小兴安岭林区生态保护与经济转型规划》和天保工程的延续,都为强化生态建设、加快科学发展步伐提供了很多的政策机遇。实现经济转型,体制机制转型是前提。在国家十二五规划中,已明确将森林覆盖率和森林蓄积量确定为约束指标。一定要从大局的高度充分认识和重视生态建设,要坚守基础,巩固成果,坚持生态优先的战略定位,将持续增加森林资源,发挥生态功能做为发展的主攻方向。

Microfluidic photomechanic infrared receptors in a pyrophilous flat bug

Infrared (IR) receptors are so far known only in boid and crotalid snakes and in three genera of pyrophilous beetles that seek out forest fires. Pyrophilous insects can also be found in other orders, however, so it can be hypothesised that IR receptors also occur in some of these species. We investigated the pyrophilous Australian flat bug Aradus albicornis and found a small number of dome-shaped sensilla (diameter 13 microm) on the prothorax, which have previously not been described. Ultrastructural investigations revealed that the sensilla are characterised by a fluid-filled inner compartment enclosed in a round cuticular shell. The cuticular apparatus is innervated by the dendrite of a ciliary mechanoreceptor, which is fluidically coupled to the inner compartment. Electrophysiological recordings demonstrated that the sensilla respond to brief warming by red laser light or to broadband IR radiation. Depending on the radiation intensity (4.4-549 mW/cm(2) tested, threshold measured as 11.3 mW/cm(2)), first spike latencies varied between 3.4 and 7.5 ms. Thus, our findings demonstrate that A. albicornis most probably possesses photomechanic IR sensilla resembling the metathoracic IR sensilla of buprestid beetles of the genus Melanophila. In the Melanophila sensillum, IR radiation causes thermal expansion of a fluid, which rapidly deforms the dendritic membrane of a mechanosensory cell. The existence of photomechanic IR receptors in both beetles and bugs demonstrates a remarkable convergent evolution towards this particular biophysical transduction mechanism and suggests that it provides selective advantages over other possible solutions.     

The interaction of temperature and sucrose concentration on foraging preferences in bumblebees

Several authors have found that flowers that are warmer than their surrounding environment have an advantage in attracting pollinators. Bumblebees will forage preferentially on warmer flowers, even if equal nutritional reward is available in cooler flowers. This raises the question of whether warmth and sucrose concentration are processed independently by bees, or whether sweetness detectors respond to higher sugar concentration as well as higher temperature. We find that bumblebees can use lower temperature as a cue to higher sucrose reward, showing that bees appear to process the two parameters strictly independently. Moreover, we demonstrate that sucrose concentration takes precedence over warmth, so that when there is a difference in sucrose concentration, bees will typically choose the sweeter feeder, even if the less sweet feeder is several degrees warmer.
