Transitional coordination in Sudan (2006–08): lessons from the United Nations Resident Coordinator's Office

With the increase in internal conflicts following the end of the Cold War, the scale and scope of the United Nations' work in conflict and post‐conflict environments grew markedly. As a result, the coordination of programming and policy in the transition from relief to recovery has been a central preoccupation of academics and practitioners alike. Intergovernmental bodies such as the United Nations Economic and Social Council (ECOSOC) have made these topics a subject of regular discussion, while some countries have altered their bureaucratic structures to respond more effectively in post‐crisis settings, particularly in cases involving the deployment of national troops. The United Nations Resident Coordinator's Office in Sudan provides a model for other transitional countries and is a useful case study of the broader challenges of post‐crisis programming. Effective coordination structures and planning/programming processes are identified as interdependent prerequisites for ensuring a successful transition from relief to recovery.

农业发展与环境协调性评价及其影响因素分析

利用中国1997~2009年间省际面板数据,在方向性距离函数模型的框架下测度农业环境技术效率,评价农业发展与环境的协调程度,并考察其演变的时空特征和驱动机制.结果表明:农业发展与环境协调性整体偏低,并且研究期内呈现波动状态;不同省(市)环境与农业发展协调性差异较大,其空间分布与经济发展水平、农业生产条件存在着对应关系;经济发展水平、农业结构变动、农业基础设施投资、农业资源禀赋和农业环境管理政策等因素对农业发展-环境协调性产生重要影响,这应是农业环境管理政策创新的重点.     

基于Global-Malmquist-Luenberger指数的沿海地带陆海统筹发展水平测度及区域差异分析

沿海地区是陆海统筹发展的区域载体,基于沿海省市的陆海复合系统进行陆海统筹发展的区域评估对海洋强国建设的理论与实践具有重要意义。论文以陆海复合经济地域系统为前提,将沿海城市形成的区域作为沿海地带,基于各沿海城市的集合作为省级沿海地带进行比较分析,建立包括经济、社会、生态以及环境4个维度指标体系,在考虑“非期望”产出的情况下运用Global-Malmquist-Luenberger（GML）指数测算沿海地带陆海统筹发展水平并进行区域差异分析。结果表明：第一,总体上,沿海地带陆海统筹发展水平全要素生产增长率大多处于无效率状态,且不考虑非期望产出明显高估了全要素生产增长率的增长;时间上,陆域、海洋以及陆海综合GML指数的变动趋于一致,呈平稳的态势;效率分解,陆海统筹发展水平全要素生产率下降明显是由规模效率变动和技术规模变动的下降所影响。第二,沿海地带正经历从“重陆轻海”到逐步实现陆海统筹发展的过程;对沿海地带陆海统筹发展水平空间差异进行分类,浙江、福建及河北属于陆域效率驱动型,环渤海地区（除河北外）、江苏、广西和海南属于海洋效率驱动型,上海和广东属于陆海效率复合型;区域差异形成的原因主要有产业结构差异、海洋产业技术门槛、海洋资源承载力以及政府政策。     

关于协同推进排污许可制与环境保护税的思考

党的十九届四中全会明确提出构建以排污许可制为核心的固定污染源监管制度体系,为推动排污许可制与各项环境管理制度衔接融合及各项法规制度的协同执法指明了作战的方向。本文在剖析排污许可制与环境保护税发展现状、面临的挑战基础上,从完善法律法规体系、建立协同作战机制、建立核算复核机制、建立大数据共享机制四个方面构建排污许可制与环境保护税衔接耦合机制,使排污许可制与环境保护税叠加在协同作战中发挥出最大效能,给企事业单位明确稳定的污染排放管控要求和预期、推动形成公平规范的环境执法守法秩序,减少污染物排放、改善环境质量、强化绿色体制保障,推动形成人与自然和谐发展的现代化建设新格局。     

忻州市土地利用现状的环境敏感区分析

随着新一轮土地利用规划修编展开,针对忻州市土地利用存在的环境问题,利用调查资料和相关研究成果,有效管理土地利用空间向环境敏感地区伸展,减缓环境敏感地区的环境压力和生态胁迫,为市域土地利用方式和分区方案制定提供环境敏感性依据.从规划方案与面临的土地生态问题入手,划分生态环境、水源保护、污染影响、优质农田以及煤矿塌陷五类环境敏感区,并进行忻州市环境敏感地综合评价,明确其空间分布范围.研究结果表明,极高敏感、高敏感区占全市总面积的4%,较高敏感区和一般敏感区分别占10.5%和7.5%,低敏感区和非敏感区分别占40%和38%.通过分析规划土地利用功能分区方案与环境的协调性, 在土地利用规划过程中,提出土地利用方式和空间布局优化对策.     

Differences in Eye and Hand Movements of Novice and Experienced Press Operators

Presses are very widely used in industrial and commercial companies and are often the source of serious accidents occurring during operation. Most of the accidents are due to inadequate training of novice operators. Continuous recordings of eye and hand movements of five novice operators and five experienced operators in press operation were made. Significant difference between novice and experienced operators was observed in eye fixation time, eye movement patterns, hand dwell time, and eye-hand coordination. Also, differences were observed in spatial distribution of eye fixations during the die-closing portion of a stroke. There were no significant differences between novice and experienced operators in the eye and the hand movement time. The results could be used as basic data to establish a guide determining the method and training period to train novice operators.     

鄂州市蔬菜地土壤重金属污染评价

为了解鄂州市蔬菜地重金属的污染状况,对鄂州市蔬菜地土壤进行采样,并对其重金属铜、铅、镉、铬、汞、砷含量进行测定。利用单项污染指数法和内梅罗综合污染指数法对其进行分析和评价,其中土壤重金属元素单因子污染指数(Pi)由大到小的顺序为:铜(Cu)>汞(Hg)>铬(Cr)>砷(As)>铅(Pb)>镉(Cd)。其中铜、汞、铬、砷属于中度污染,铅、镉处于警戒线中。内梅罗综合污染指数法表明鄂州蔬菜地土壤整体受到了轻度的重金属污染.     

中国规划环评中协调性分析的作用

协调性分析是规划环境影响评价的重要组成部分,它的分析对象是被评价的规划草案及其相关的政策、法规、规划等。在以规划草案为评估对象的环境影响评价中,协调性分析能够起到两种作用：解释制定规划草案的“政策背景环境”,和检查规划草案是否存在资源保护、环境保护方面的缺陷和不足。这两种作用不能被截然分开。协调性分析的目的是帮助环评单位和公众更好地理解规划制定的背景,以及使规划环评针对草案的缺陷与不足提出相应的环境目标和环境保护对策。分析结果一般可以使用矩阵来表示。如果规划环评可以早期介入到规划的制定中,描述“政策背景环境”和制定可选择性方案这两个程序就可以达到协调性分析的目的．因此不再需要进行专门的协调性分析。
