对杭州市部分自然灾害应急预案完备性评价的实证研究

采用故障树分析方法,从灾害的预防与应急准备、监测与预警、应急响应、后期处理4个方面,对2008年以前杭州市编制的部分自然灾害应急预案的完备度进行评价。结果表明:各类自然灾害应急预案的完备度不一,一些应急预案具有较高的完备度,而一些应急预案完备度偏低;大部分应急预案在灾害监测与预警方面具有较高的完备度,部分应急预案在灾害预防与应急准备、灾害后期处理完备度偏低;各应急预案中志愿者队伍的建设、灾害风险评价、应急人员的安全防护、灾后的保险理赔、重要设施的安全防护、启动应急避难场所等基本事件的缺失率较高,反映了部分应急预案编制过程中灾害全过程管理理念的缺失。

Monitoring urban growth and detecting land-cover changes on the Istanbul metropolitan area

Istanbul is the most populated city of Turkey with a population of around 10.58 M (2000) living on around 5,750 km². In 1980, the population was only 4.7 M and then it has been more than doubled in only two decades. The population has been increasing as a result of mass immigration. An urbanization process continues and it causes serious increases in urban areas while decreasing the amount of green areas. This rapid, uncontrolled, and illegal urbanization accompanied by insufficient infrastructure has caused degradation of forest and barren lands in the metropolitan area, especially through the last two decades. The watershed basins inside the metropolitan area and the transportation network have accelerated the land-cover changes, which have negative impacts on water quality of the basins. Monitoring urban growth and land cover change will enable better management of this complex urban area by the Greater Istanbul Metropolitan Municipality (GIMM). A temporal assessment of land-cover changes of Istanbul has been documented in this study. The study mainly focuses on the acquisition and analysis of Landsat TM and Landsat GeoCover LC satellite images reflecting the significant land-cover changes between the years of 1990 and 2005. Raster data were converted to vector data and used in Geographic Information Systems (GIS). A database was created for Istanbul metropolitan area to plan, manage, and utilize statistical attribute data covering population, water, forest, industry, and topographic position. Consequently an overlay analysis was carried out and land use/cover changes through years have been detected for the case study area. The capability of Landsat images in determining the alterations in the macro form of the city are also discussed.     

A Model for Landscape Planning Under Complex Spatial Conditions

We present a new mathematical programming framework that is adaptable to a variety of spatially explicit landscape problems in environmental investment, conservation, and land-use planning, transport planning, and agriculture. As part of capturing spatial interdependencies, the framework considers decision variables at two levels, finely spaced grid cells and landholdings. We applied the framework to an environmental investment problem using objective functions representing biodiversity and carbon sequestration. We also tested the model to optimize the path of a road through part of the landscape. Using the Nambucca case study in eastern Australia, we applied a hybrid greedy randomised adaptive search procedure (GRASP) to find solutions to the model.     

Implementation of resource management plans: identifying keys to success

One of the primary challenges in resource and environmental planning is successful implementation of plans. Plan implementation is a complex process influenced by many factors. This study identifies 19 criteria affecting implementation success and tests the impact of these criteria through a case study of collaborative plan implementation in British Columbia, Canada. The significance of criteria and degree to which they are met is assessed by a survey of senior officials responsible for plan implementation. An implementation evaluation index (IEI) is constructed to assess the quality of plan implementation systems and best practices for effective implementation are identified.     

基层环境执法中环境行政强制问题的探讨

环境行政强制包括环境行政强制措施和环境行政强制执行.在基层环境执法实践中,环境行政强制措施尤其是环境行政强制执行存在许多困惑和问题,拓展环境行政强制措施,给予环保部门一定的行政强制执行权是提高基层环境执法效率和遏制环境污染的有效途径.     

土地一级开发环境影响评价初探

衔接土地利用规划和建设项目的土地一级开发伴随着土地政策的改革而出现。目前土地一级开发环境影响评价处于起步阶段,缺乏对这项工作系统的研究。本文结合工作中的实践经验,从土地一级开发环境影响评价实施的意义、作用和评价目的等方面对土地一级开发的环境影响评价进行了论述,分析了其环境影响评价存在的问题,总结了土地一级开发环境影响评价的技术要点,并对完善土地一级开发环境影响评价制度提出建议。     

区域规划环境影响跟踪评价的理论研究

随着环境影响评价制度的深入实施,其实施领域已由项目环评向区域环评和规划环评转变,评价内容也由广泛实施的预测评价向后评价和跟踪评价转变。然而,对于区域规划环评的评价层次、评价程序和评价内容,目前还没有明晰的认识;同时,对于促进规划环评有效实施的跟踪评价,其相关的理论和实践研究几乎没有。文中就此问题作了深入探讨。     

The 2004 Madrid train bombings: an analysis of pre-hospital management

The terrorist train bombings in Madrid, Spain, on 11 March 2004 triggered a swift and massive medical response. This paper analyses the pre-hospital response to the attacks to gain insight into current trends in disaster management among Madrid's Emergency Medical Services (EMSs). To this end, the existing emergency planning framework is described, the basic structures of the different EMSs are presented, and the attacks are briefly depicted before consideration is given to pre-hospital management. Finally, an explanation of the main underlying misconceptions in emergency planning and management in Madrid is provided to aid understanding of the origins of some of the problems detected during the response. These are attributable mainly to inappropriate planning rather than to mistakes in field-level decision-making. By contrast, many of the successes are attributable to individual initiatives by frontline medics who compensated for the lack of clear command by senior managers by making adaptive and flexible decisions.     

市级国土空间规划核心指标纵向传导研究——以湖南省常德市为例

核心指标纵向层级传导作为市级国土空间规划的关键内容,对市域国土空间格局优化及规划统筹具有重要意义。针对当前指标传导研究不充分、不精细等问题,遵循“核心传导指标选择→指标传导技术逻辑构建→情景模拟预测”的研究思路,以常德市为例研究其2035年国土空间规划“市→县（区）”的核心指标传导。结果表明：（1）基于“指标全域总量预测—指标空间布局模拟—指标分区分类传导”的传导技术逻辑,通过SD与GeoSOS-FLUS模型的耦合集成利用,可有效实现市级国土空间规划核心指标“自上而下”与“自下而上”相结合的科学传导。（2）构建“人—地—业”协调的常德市国土空间利用SD模型,预测获得2035年市域核心指标总量,相应国土利用综合效益达12994.25亿元,相比2018年提升207.75%。（3）从指标传导结果来看,2035年常德市各县（市、区）社会经济类指标除常住人口规模指标外均保持增长趋势,边界类指标实现“只增不减”,用地类指标变化各异,但总体契合常德市主体功能区建设方向,核心指标传导结果符合实际。
