Integrity of Tailings Infrastructure and Information Management: A GIS-Based Conceptual Model

Managing the integrity of tailings infrastructure is an important aspect of handling mine tailings. Unfortunately, little research is directed towards its efficient modeling. This paper presents salient aspects of tailings management. It proposes an integrated geographic information systems (GIS)-based conceptual model for efficient handling of these aspects. The paper also discusses the various integrated modules and comments on the systematic implementation of the model to achieve desired results. The modules include: structural integrity management (SIM), release impact assessment (RIA), and hazardous risk assessment and control (HRAC).

环境监测能力建设项目管理思路与实现

近年来,环境监测能力建设项目资金投入不断加大,项目规模增长迅速,实施任务日益繁重,项目绩效考核要求越来越高,但项目管理还处于比较粗放的状态。在分析环境监测能力建设项目管理现状和需求的基础上,提出通过转变项目管理模式、强化信息支撑手段、完善制度建设、培养管理人才等多种手段,提高项目管理的科学性和时效性,实现重点项目管理的精细化、科学化和规范化。     

Multi-Criteria and Multi-Perspective Analysis of Contaminated Land Management Methods

Errors in environmental resource management over the years have created pollution problems in some areas which are difficult to handle, regardless of the development of knowledge and technologies. This is particularly true in the case of soil pollution. The negative effects of persistent pollutants have been observed for a long time. For instance, lead and cadmium remain in the soil for centuries, during which time they are absorbed by plants and simultaneously cause secondary air pollution. The authors made an attempt to describe and assess the possible options of dealing with the problem of contaminated land in Katowice District. Considering the necessity of a multilateral approach, a pairwise comparison technique has been chosen as the most suitable to show the complexity of the problem. The different variants of actions aimed at preventing the pollutants from getting into the food chain were analyzed against a set of criteria, consisting of the following issues: time, cost, effectiveness, social acceptance, feasibility. The relative importance of actions were judged by the team of experts using the Saaty method. Also, a two-perspective assessment (the two different stakeholders), which involves considering the perspective of an owner of a piece of contaminated land and an ecologist has been performed. The results of comparative, multicriteria and multi-perspective assessment indicate the following:- the best method for contaminated agricultural land management is willful and controlled cultivation,- other recommended actions are deep ploughing and phytoremediation,- there is not much acceptance for the other methods.

对克拉玛依市区大气尘污染的特征及变化规律进行了全面的分析和研究。结果表明,市区的尘污染有加重的趋势,降尘属中度污染,道路尘污 染也较严重。提出了一些具体的防治对策。     

新疆环境监测网络的建设及发展对策

新疆环境监测网络建立三十多年来,已经初步形成了水环境、环境空气、声环境、生态环境和污染源等监测网络,较好地承担了各环境要素例行监测、突发性环境污染事故应急监测和环境科研等监测任务,为各级环保决策提供了有效的技术支持。然而,随着环境管理工作的不断深入,新疆环境监测网络所呈现的一些新老问题已成为不适应环境管理需求的制约因素,本文通过分析新疆环境监测网络中存在的问题,提出了发展对策。

污染源普查成果在环境管理中的应用

历经3年的第一次全国污染源普查现已基本结束。此次污染源普查中获得了大量珍贵的污染源基础性数据,合理开发这些数据,对提高环境监察、项目审批、污染源治理及减排等工作,对加强环境管理有着不可估量的作用。结合唐山市的环境管理工作,阐述了利用普查成果,可对唐山市环境保护工作的开展起到积极的促进作用。     

基层环境监测站业务风险管理现状与对策

简述了基层环境监测业务风险管理现状及存在的问题,对业务风险管理的认识程度不高,业务风险管理的系统性不强,缺少环境监测业务风险管理指导性文件。提出,应树立正确的环境监测业务风险理念,建立环境监测业务风险管理组织机构,健全与监测工作紧密结合的业务风险管理体系,优先监控风险高的环境监测工作,大力培养风险管理人才。     

自动监测站第三方运维管理的思考

随着自动监测技术的不断发展,其连续、稳定的监测优势正在逐步代替手工监测,各地监测部门投入了大量的资源和精力建成了大量的空气、水质自动站,在灰霾监测、河道水质监管、大环境预警方面等都起到了积极作用。由于自动站数量多,工作任务复杂繁重,因此大部分地区都采用第三方托管模式进行自动站日常运维管理。如何有效的进行权责分配、提高工作效率、减少管理摩擦等成为业主方不可回避和亟待解决的问题。根据实际管理实践,结合一些实用的管理经验,提出了一系列相关措施。
