Network design for water quality monitoring of surface freshwaters: a review

To date, many water quality monitoring networks for surface freshwaters have been rather haphazardly designed without a consistent or logical design strategy. Moreover, design practices in recent years indicate a need for cost-effective and logistically adaptable network design approaches. There are many variables that need to be included in a comprehensive yet practical monitoring network: a holistic appraisal of the monitoring objectives, representative sampling locations, suitable sampling frequencies, water quality variable selection, and budgetary and logistical constraints are examples. In order to investigate the factors which affect the development of an effective water quality monitoring network design methodology, a review of past and current approaches is presented.     

含多弱层复合边坡滑坡治理三维数值分析

白音华二号矿滑坡区边坡治理工程是针对稳定性差的南帮非工作帮和南排土场构成的复合边坡进行的。滑坡体受多层弱层控制,治理过程中易导致边坡失稳,所以治理工程采取分区开采的条采方案,充分利用边坡治理的三维效应来进行边坡的失稳破坏研究和稳定性分析。选取滑坡区的典型剖面作为研究对象,基于强度折减方法(SRM),应用有限差分FLAC3D软件,在两种开挖条件下,对含多弱层的复合边坡的稳定性规律和破坏机制进行了数值模拟分析,揭示了多弱层对复合边坡的失稳破坏及稳定性的影响。研究结果表明,治理工程中,弱层被揭露一定宽度,滑体沿煤底板弱层水平错动、竖直方向拉裂破坏;随弱层暴露宽度的增加,边坡稳定性明显降低,说明治理边坡具有三维效应;开挖至3-3煤层底板,开挖坡角20°,弱层暴露宽度为400m,边坡的稳定系数刚好达到安全储备系数1.1,建议矿方首选此方案,可以最大限度的回收煤炭资源。     

ON THE MEASUREMENT OF ENVIRONMENTAL IMPACTS OF PUBLIC PROJECTS FROM A SOCIOLOGICAL PERSPECTIVE1

ABSTRACT: The major objectives are (1) to identify the problems involved in measuring the environmental impacts of public projects from selected perspectives, and (2) to elaborate a sociological approach used in an empirical investigation in that respect. The construct of environmental impact of a planned action is generally operationalized from different perspectives and with different methodological emphases in the various disciplines. Even the term environment does not elicit agreement among users as to its exact meaning. Although there has been a steady increase in the number of studies from a sociological perspective concerning environmental problems, there is lack of sociological counsel in writing environmental impact statements. Overall, we lack sociological methodology and operational procedures for that purpose. In an attempt to bring some empirical focus to this field, attitudinal measures employed to discover how residents of a river basin perceived negative and positive environmental impacts of a proposed watershed development project are reviewed. These come from a study of creation of the Cooper Reservoir and Dam in Texas. Data on 343 heads of households m the selected areas were collected through structured questionnaires with items on personal information, a vested interest scale, a knowledge of the project scale, and an environmental impact scale. Data show that perception of impacts by residents is influenced significantly by degree of their vested interests involved. Variables for inclusion in a sociological model of environmental impact are suggested.     

安全生产“十一五”规划实施评估技术研究

对安全生产＂十一五＂规划进行了特征分析,明确了规划评估的工作目标,研究提出了规划评估技术体系,包括评估逻辑设计原则、评估总体框架和评估技术路线。安全生产＂十一五＂规划实施评估应重点从目标实现评估、任务完成评估、政策措施评估三方面入手,评价目标实现一致性程度,评价任务实施情况及其作为目标战略的有效性如何,评价政策措施的制订与贯彻对目标实现与任务完成的支撑程度,在此基础上评价规划实施的总体效果,并对存在的问题进行原因分析,最后提出做好安全生产＂十二五＂规划的对策建议。实例应用表明,国家安全生产＂十一五＂规划实施进展总体比较顺利,取得良好成效,本文提出的评估技术体系对各级政府开展安全生产规划实施评估具有指导意义。     

基于煤矿安全生产标准化的双控机制APP系统研究

针对我国煤矿安全生产标准化工作中数据采集的时效性差、数据录入工作量繁琐、数据汇总分析不明确的问题,利用易安卓编程语言与SQLite数据库技术,采用瀑布生命周期模型的软件开发方法,以《煤矿安全生产标准化考核定级办法》中双控机制的基本内容为依据,设计包括个人信息管理、法律知识库检索、安全风险分级管控、事故隐患排查治理、数据可视化分析、其他6大功能模块的APP系统。结果表明:该系统可提供适合相关管理人员使用的可视化界面,减少了复杂繁琐的工作量,为标准化工作的定点巡检与数据的完整性提供了良好的技术支持,也为非煤矿山、冶金、石油化工等行业的标准化工作实现信息化管理提供了较好的应用模式。
