网络创意产业、低碳经济与上海都市型工业园转型

兴起于1990年代的都市型工业园为大都市经济发展、城市充分就业、城市空间合理利用做出了积极贡献。然而面临信息技术快速发展、低碳城市建设和大都市新经济迅速兴起,都市型工业园转型势在必行。深入剖析网络创意产业与低碳经济的本质,认为网络创意产业是都市型工业园转型和发展低碳经济的首选。以上海为例,采用统计方法对比分析都市工业行业发展现状和制约因素,从创意产业和低碳经济的内涵针对都市工业园转型,建构了都市工业园转型的理念、路径和规划策略。通过建构上海典型都市工业园转型与网络创意产业发展耦合路径引介,为我国其他都市区工业园转型和建设提供借鉴     

浅谈音乐教育中的教学美

在音乐课上对学生进行审美教育是对学生实施美育的重要途径。但长期以来,我国传统的音乐教育偏重"专业化",过于强调音乐知识传授的系统性,忽视了音乐教育的审美愉悦性。在音乐教育中,充分发挥其审美能力与文化素养的教学美、创新精神与实践能力的教学美、音乐教育联系生活实际的教学美、音乐教育与现代技术相结合的教学美、以情感教育为纽带的教学美,将会达到以美育人的目的。

Advances in air pollution control for key industries in China during the 13th five-year plan

Industrial development is an essential foundation of the national economy, but the industry is also the largest source of air pollution, of which power plants, iron and steel, building materials, and other industries emit large amounts of pollutants. Therefore, the Chinese government has promulgated a series of stringent emission regulations, and it is against this backdrop that research into air pollution control technologies for key industrial sectors is in full swing. In particular, during the 13th Five-Year Plan, breakthroughs have been made in pollution control technology for key industrial sectors. A multi-pollutant treatment technology system of desulfurization, denitrification, and dust collection, which applies to key industries such as power plants, steel, and building materials, has been developed. High-performance materials for the treatment of different pollutants, such as denitrification catalysts and desulfurization absorbers, were developed. At the same time, multi-pollutant synergistic removal technologies for flue gas in various industries have also become a hot research topic, with important breakthroughs in the synergistic removal of NO_x, SO_x, and Hg. Due to the increasingly stringent emission standards and regulations in China, there is still a need to work on the development of multi-pollutant synergistic technologies and further research and development of synergistic abatement technologies for CO₂ to meet the requirements of ultra-low emissions in industrial sectors.     

京津冀及周边地区区域贸易隐含二氧化硫排放

京津冀及周边地区(包括北京、天津、河北、山东、山西和河南)是我国大气污染重点控制区域,厘清这一地区内部各省各行业之间贸易隐含污染物排放是加强区域产业协作、推进区域大气污染联防联控的重要前提.本研究以二氧化硫(SO_2)为对象,结合自下而上排放清单与中国多区域投入产出(MRIO)模型,估算了2012年京津冀及周边地区各省(直辖市)和各行业之间的贸易隐含污染排放,并基于产业链分析了区域贸易对重点行业SO_2的排放贡献,识别了主导排放的区域贸易产业链.研究结果表明,在京津冀及周边地区六省市之间,河北和山西是主要隐含排放输出区域,北京和天津是主要的隐含排放输入区域.京津冀及周边地区SO_2排放主要来源于能源动力行业、金属冶炼和制品制造业、非金属矿物制品和化学工业,而装备制造业、建筑业和服务业是拉动四类重点行业SO_2排放的主要产业.进一步分析六省市内部排放与区域产业链之间的关系发现,山西省是主要的能源消费SO_2排放输出区域;河北省是主要的金属冶炼和金属制品隐含排放输出区域;河北和河南是主要的非金属矿物制品隐含排放输出区域;山西是主要的石化与化工隐含排放输出区域.以上结果有助于理解京津冀及周边地区大气污染排放与产业结构的关系,为制定区域环境管理政策,优化区域产业结构提供支撑.     

中国1990~2004年生态足迹动态变化效应的分解分析

通过构建生态足迹分解模型,论文将中国1990~2004年生态足迹的动态变化分解为经济规模、产业结构和足迹强度这3种因素的变化效应,并对各分解效应进行了测度与分析。结果表明:生态足迹年度间变化均值为1.065 5×10⁸hm²。其中,由经济规模、产业结构和足迹强度所引起的足迹变化分别为2.108 2×10⁸hm²,-0.439 8×10⁸hm²和-0.602 9×10⁸hm²。总的看,经济规模的变化助长了总足迹的增长,而足迹强度和产业结构的变化对总足迹的扩张起到了一定的遏制作用。生态足迹变化是由各因素共同作用的结果,而在不同时期各因素对足迹变化所发挥的效应不同。该研究结果对于理解我国生态足迹变化与经济发展之间的关系,以及产业发展政策调整及可持续发展研究具有一定参考价值。     

Improving sustainability through effective reuse of product returns: minimizing waste in a batch blending process environment

A case study of a successful reuse program in a batch blending production environment is presented. This program involves not only addressing the company's own potential waste, but also working with distributors and customers to take back and reuse product, thus eliminating the customers' burden of disposal. Implications of the program for downstream supply chain partners are identified and a structured approach for implementation is presented. Modification for use in similar production environments is possible, enhancing sustainability, while providing environmental as well as economic benefits.     

我国行业水资源消耗的关联度分析

选取2007年相关数据进行整理分析,应用基于假设抽取法的水资源消耗产业关联度计量模型,比较各行业水资源的直接消耗和纵向集成消耗,定量测算出我国行业间水资源的流动转移情况.通过分析得到:不同行业的水资源直接消耗量与满足自身需求所需的水资源量有所差异,但是对于经济系统而言,所有行业水资源的直接消耗总量等于为满足最终需求所需的水资源总量,即水资源在经济系统的不同行业之间发生了转移;在经济系统中,农业、基础工业作为产业链上游行业将大量的水资源通过中间投入的方式转移到其下游行业中,轻工业、高科技工业等产业链下游行业的直接消耗的水资源无法满足自身需求,必须从其上游行业转移水资源;水资源从产业链的上游逐级向下游转移,维持着经济系统产品的生产与交换;如果行业的最终需求不变,单纯调整产业结构仅是将水资源消耗量大的行业进行区位或行业上的转移,而经济系统水资源消耗的总量并没有改变.本文通过定量化的方式来研究行业水资源消耗关联,初步揭示了水资源在行业间的消耗规律,能够为产业调整提供新视角,为产业结构调整政策提供更为科学的依据.     

Wild fruits as a contribution to sustainable rural development: a case study from the Garhwal Himalaya

Garhwal Himalaya is an important source of wild fruit species. These wild fruit trees grow abundantly across an altitudinal gradient of Himalaya and the majority of them bear fruits during summer. Fruit varieties are eaten raw by the local inhabitants of the region and whilst they are a rich source of protein, carbohydrate, fat and other elements, compared to cultivated fruits, they have not yet been considered as a source of alternative food products. About 13 potentially exploitable species of wild fruits and one semi-domesticated species having high potential for exploitation were selected for study; six (Aegle marmelos, Berberis asiatica, Hippophae rhamnoides, Myrica nagi, Rubus ellipticus and Prunus armeniaca) were examined in detail for their economic potential. Among the wild fruits, Hippophae rhamnoides was found to be economically efficient, followed by Aegle marmelos, Rubus ellipticus and Myrica nagi, respectively. Prunus armeniaca, a semi-domesticated and less utilized fruit of the higher Himalaya, provides better economic returns on an annual basis. The authors have recently made an attempt to utilize these wild fruits as a source of income, particularly for poor rural inhabitants and unemployed youths of the region by making a variety of edible products such as jam, jelly, juice, squash, sauce, etc. The enterprise was demonstrated to the people to encourage them to adopt it in the form of a small village-level cottage industry. The present paper discusses the distribution, botany, phenology, yield, ethnobotany, and uses of these species, and the cost-benefit analysis of food products prepared from them.     

高危行业同类型同等级事件风险要素评价

为提高高危行业安全管理水平,研究风险要素的评价模型。借鉴作业条件危险性评价LEC法理论意义,针对其主观性和间接性太强的缺憾进行了实质性地改进。同时,通过给出风险源强度评估模型及各风险要素强度评估模型,设计同类型同等级事件风险要素的风险贡献度模型。在此基础上,结合改进后的LEC法,建立同类型同等级事件风险要素的风险值模型,风险警戒标准模型以及风险警戒状态模型。验证结果表明:所建模型对风险要素的评价与实际情况较为吻合。
