基于OSHMS的煤矿模糊综合安全评价管理模型的建立

针对目前我国煤矿企业安全管理现状,以一种全新的思路结合职业安全健康管理体系(OSHMS)的系统化体系结构及其先进之处,以预防为主,持续改进为动力,建立了基于生产过程的绩效测量、人员职责分配、运行控制和风险管理为核心的4个主要因素的安全评价管理模型;并以此为指导建立安全评价指标体系框架,运用模糊综合安全评价的方法对指标体系进行合成;最后,结合矿井生产过程中的供电系统,对淮南潘三矿现场进行实例应用,证明其可行性。该管理模型对煤矿企业安全管理有推广和借鉴意义,可望为煤矿企业通过安全管理实现科技兴安提供一种更可靠,更有效的安全管理方法。     

城市生态安全多层次灰色综合评价

从城市生态安全的基本内涵出发,根据压力(pressure)-状态(state)-响应(response)模型,从生态系统压力、生态系统状况、生态系统响应3方面构建一个4层次的城市生态安全评价指标体系,运用灰色系统理论,构建了城市生态安全多层次灰色综合评价模型,并结合实例进行计算。评价结果与实际情况基本相符,表明该模型能有效地利用评价指标的信息,所给出的综合评价值既能用于描述所评价城市的生态安全状况,亦可对不同城市的生态安全状况进行比较,对更加科学合理地评价城市生态安全状况具有参考价值。

城市滨水景观评价研究初探——以南京市莫愁湖滨水区为例

城市滨水区一直被认为是一个城市最具活力和生态价值的区域,但伴随着城市职能的转型以及水运地位的下降,世界上大部分的滨水区都经历了从繁荣到衰败的过程。然而目前,随着城市人群的生态需求与审美需求的进一步提高,城市滨水区又面临着复兴之势,这也对城市滨水号观设计以及作为其基础而存在的滨水景观评价提出了新的要求。因此。本文将以成分代用模式评价方法为指导,以南京市莫愁湖滨水区为案例对其进行景观评价,并基于此获取影响滨水区景观质量的重要因素,以期对以后的滨水区规划设计起到一定的指导作用。     

Development of a risk-based index for source water protection planning, which supports the reduction of pathogens from agricultural activity entering water resources

Source water protection planning (SWPP) is an approach to prevent contamination of ground and surface water in watersheds where these resources may be abstracted for drinking or used for recreation. For SWPP the hazards within a watershed that could contribute to water contamination are identified together with the pathways that link them to the water resource. In rural areas, farms are significant potential sources of pathogens. A risk-based index can be used to support the assessment of the potential for contamination following guidelines on safety and operational efficacy of processes and practices developed as beneficial approaches to agricultural land management. Evaluation of the health risk for a target population requires knowledge of the strength of the hazard with respect to the pathogen load (massxconcentration). Manure handling and on-site wastewater treatment systems form the most important hazards, and both can comprise confined and unconfined source elements. There is also a need to understand the modification of pathogen numbers (attenuation) together with characteristics of the established pathways (surface or subsurface), which allow the movement of the contaminant species from a source to a receptor (water source). Many practices for manure management have not been fully evaluated for their impact on pathogen survival and transport in the environment. A key component is the identification of potential pathways of contaminant transport. This requires the development of a suitable digital elevation model of the watershed for surface movement and information on local groundwater aquifer systems for subsurface flows. Both require detailed soils and geological information. The pathways to surface and groundwater resources can then be identified. Details of land management, farm management practices (including animal and manure management) and agronomic practices have to be obtained, possibly from questionnaires completed by each producer within the watershed. To confirm that potential pathways are active requires some microbial source tracking. One possibility is to identify the molecular types of Escherichia coli present in each hazard on a farm. An essential part of any such index is the identification of mitigation strategies and practices that can reduce the magnitude of the hazard or block open pathways.
