我国危险化学品产业转移及安全风险分析*

为深入分析我国国内（不含港澳台,下同）危险化学品产业转移及安全风险,通过调研产业转移现状,统计典型地区产业政策、转移企业数量、转移时间及安全生产形势,分析产业转移带来的安全风险。研究结果表明:危险化学品产业转移呈现明显地域趋势,从以江苏、浙江为主的东部沿海地区向中西部等地区转移;转移时间集中在2个阶段,分别是:2002—2008年、2017—2020年;转移集中在精细化工、炼焦、煤化工等产业,医药等高端产业未发生转移;危险化学品产业转移安全风险主要表现在:“重经济,轻安全”现象突出、转移项目安全风险高、承接地基础薄弱、人才储备不足等方面;针对呈现的产业转移安全风险,提出相关对策措施及建议。研究结果可为我国危险化学品产业转移安全风险管控政策措施制定提供相关数据与理论支撑。     

工业园区低碳发展模式评估与规划分析

通过对工业园区低碳发展模式的评估,分析其低碳发展的能源特征、经济特征与人力特征,并确定工业园区二氧化碳减排的潜力能源。基于能源-碳减排(EC)、经济-能源-碳减排(EEC)和人力-经济-能源-碳减排(HEEC)三种不同情景,在未来发展的一定规划期内,对工业园区具有二氧化碳减排潜力的能源进行规划分析,确定其年递减率,从而实现工业园区不同情景下的二氧化碳减排。通过实际案例研究,证明了评估与规划分析模型的可行性。     

山西省城乡统筹发展效率的DEA分析

基于2009年山西省11个地级市城乡统筹发展的面板数据,运用数据包络分析（DEA）评价了各区域的城乡统筹发展效率,对其空间差异变化特征与规律进行了分析。结果表明,山西省城乡统筹发展效率总体上呈＂中部较高,普遍分化＂的分布特征,并存在两大＂DEA有效＂集群。自改革开放以来,山西省逐渐形成了中、东、西三大经济地带,即中部盆地区、东部山地区和西部高原丘陵区。规模效率是当前制约山西省城乡统筹发展综合效率的主要方面。全省普遍存在投入冗余现象,可通过优化环境、产业结构高级化、突出特色产业、提升产业技术、提高劳动力素质和城市化水平等途径来提高区域的城乡统筹发展效率。各区域之间城乡统筹发展效率的空间差异显著;对2009年山西省11个地级市进行相对效率分析,得出相对有效值为1的城市居多,北部朔州市和南端运城市相对效率差异明显,最后提出了相关政策建议。     

浅析低碳技术的评价方法

低碳技术可分为3类:减碳技术、无碳技术、去碳技术,选择最优低碳技术是一个项目能否成功的关键。低碳技术评价的内容通常从能源使用率、经济效益、生命周期方面进行评价,对技术的综合性评价的基本方法大致有层次分析法、综合评分法、德尔菲法、熵值法、模糊综合评判法等,这些方法渗透于指标权重分析、模型建立评价当中。通过研究对这些技术的评价方法,确定最优的技术项目,以促进循环经济及可持续发展战略的实施和进行。

Development and Adoption of a Simple Nonpoint Source Pollution Model for Port Phillip Bay,Australia

New computing tools and approaches allow tailored development of software to meet the needs of environmental managers. The processes required for such tailoring fit well with adaptive management concepts where, as knowledge and system understanding develop among managers, the software can be developed or replaced to match. This paper reports on development and adoption of a simple nonpoint source pollution modeling tool, including technical aspects of data support for modeling and social aspects of software design. The software, named FILTER, used a unit load model to generate expected pollutant loads from subcatchments of Port Phillip Bay, Australia. Monitoring data were used for calibration to modify the delivery of generated pollutants to receiving waters. Spatial, tabular, and charting software components were used to provide alternative forms of output visualization. FILTER was developed using a process that resulted in manager-stakeholders taking responsibility for setting of model parameter values and operation of the user interface, thereby encouraging uptake. The inclusive development process, tailoring of the software to manager needs and styles of usage, and matching of model complexity to data and knowledge, resulted in a successful application that has become the current agreed system representation among disparate stakeholder organizations.     

Transforming open mining pits into fish farms: Moving towards sustainability

The legacy of mining activities has typically been land ‘returned to wildlife’, or, at some sites, degraded to such an extent that it is unsuitable for any alternate use. Progress towards sustainability is made when value is added in terms of the ecological, social and economic well‐being of the community. In keeping with the principles of sustainable development, the innovative use of flooded open pits and tailings impoundments as commercial, recreational or ornamental fish farms should be considered in some locations, as it could make a significant contribution to the social equity, economic vitality and environmental integrity of mining communities. This article highlights the growing significance of aquaculture and explores the benefits and barriers to transforming flooded pits and impoundments into aquaculture operations. Among other benefits, aquaculture may provide a much‐needed source of revenue, employment and, in some cases, food to communities impacted by mine closure. Further, aquaculture in a controlled closed environment may be more acceptable to critics of fish farming who are concerned about fish escapes and viral transmissions to wild populations. Despite the potential benefits, aquaculture in flooded pits and impoundments is not without its complications — it requires a site‐specific design approach that must consider issues ranging from metals uptake by fish, to the long‐term viability of the aquatic system as fish habitat, to the overall contribution of aquaculture to sustainability.     

生态足迹分析方法及其在国内的应用

湖北省棉花生产变化影响因子研究

利用灰色关联分析方法,探讨了湖北省近50多年来棉花生产的总体变化趋势及影响湖北省棉花总产量的各项因子。结果表明,棉花单产是影响湖北省棉花总产量的首要因子,播种面积对棉花总产的影响仅次于单产,其制约作用呈上升趋势;自然因素对棉花总产量的影响不断下降;有效灌溉面积对湖北省棉花总产量有逐步增强的制约趋势;农业机械总动力、农业用电量以及化肥施用量对湖北省棉花总产也有着重要的影响。
