数据包络分析(DEA)模型在清洁生产评价中的应用

清洁生产技术方案评价对于指导企业实施清洁生产有重要意义。将污染物产生量数据作为一种输入引入数据包络分析(DEA)模型，利用该模型对清洁生产技术方案中的投入、产出和污染物发生量进行有效性评价。分析不同方案相对效率值、目标改进值，发现最有效的清洁生产技术方案，达到经济效益和环境效益的统一。本研究为企业筛选和决策可实施清洁生产技术方案提供技术理论支持。

Evaluation of the california environmental quality act

The California Environmental Quality Act (CEQA) has evolved from a mini-NEPA, first enacted in 1970, into a procedural act that affects the approval process of all large developments in California. In 1990, California local governments produced over 1600 environmental impact reports and 30,000 initial studies under CEQA. Because of its widespread use, CEQA has periodically drawn the attention of the state legislature, most recently in 1993, when over 60 CEQA reform bills were introduced. This paper describes the CEQA process and evaluates its success at meeting its explicit and implicit goals. The research includes a statewide survey of CEQA practice, sent to the planning departments of all 513 local governments in California in 1991. Survey respondents agreed that CEQA helps in evaluating environmental impacts, reducing impacts, informing the public, and coordinating public agency review. It is effective in reducing the environmental impacts of individual projects, but is not as effective in improving environmental quality on an areawide scale. This research concludes that CEQA has led to positive outcomes and is not as deeply flawed as many of its critics claim. Still, CEQA as currently designed may not be the optimal vehicle for ensuring environmental quality.

ENHANCING FECAL COLIFORM TOTAL MAXIMUM DAILY LOAD MODELS THROUGH BACTERIAL SOURCE TRACKING1

ABSTRACT: Surface water impairment by fecal coliform bacteria is a water quality issue of national scope and importance. In Virginia, more than 400 stream and river segments are on the Commonwealth's 2002 303(d) list because of fecal coliform impairment. Total maximum daily loads (TMDLs) will be developed for most of these listed streams and rivers. Information regarding the major fecal coliform sources that impair surface water quality would enhance the development of effective watershed models and improve TMDLs. Bacterial source tracking (BST) is a recently developed technology for identifying the sources of fecal coliform bacteria and it may be helpful in generating improved TMDLs. Bacterial source tracking was performed, watershed models were developed, and TMDLs were prepared for three streams (Accotink Creek, Christians Creek, and Blacks Run) on Virginia's 303(d) list of impaired waters. Quality assurance of the BST work suggests that these data adequately describe the bacteria sources that are impairing these streams. Initial comparison of simulated bacterial sources with the observed BST data indicated that the fecal coliform sources were represented inaccurately in the initial model simulation. Revised model simulations (based on BST data) appeared to provide a better representation of the sources of fecal coliform bacteria in these three streams. The coupled approach of incorporating BST data into the fecal coliform transport model appears to reduce model uncertainty and should result in an improved TMDL.     

我国安全学科学历教育的困境与对策

我国安全形势严峻的重要原因是安全科技人才缺乏。安全学科学历教育作为我国安全科技高级人才培养的主要渠道之一,为国家造就和输送了大批安全科技人才。但是,由于安全学科学历教育体制没有很好适应市场经济的发展,遇到了不少难以解决的问题。依据对高校和煤炭企业调查所获得的资料,统计发现:目前我国安全学科学历教育所面临的主要问题是专业设置的局限性、培养目标的雷同性和课程设置的低通用性;社会对安全人才需求与目前高校安全专业招生和毕业生就业之间存在的突出矛盾。在详细调研和分析的基础上,提出了相应的安全人才后备队伍建设应采取的对策,即加大政府调控力度、实施“人才兴安”战略,深化教育教学改革、培养高素质安全人才。

四川德阳地区龙风水库西岸滑坡稳定性分析及防治

本文在对四川德阳地区龙凤水库西岸滑坡的地质地貌条件及变形迹象进行深入调查的基础上,对该滑坡的主要成因及稳定性进行了分析与评价,并有针对性地提出了工程防治方案。研究表明,疏松透水的土层、较强的降雨以及人类耕作活动是导致滑坡发生的主要因素。在天然状态下该滑坡稳定或基本稳定;在天然+地震状态下,该滑坡欠稳定或不稳定;在连续高强度降雨状态下,该滑坡不稳定。故采取截、排水及抗滑桩等工程措施是防治该滑坡的有效方案。
