论促进企业环境守法的制度建构

企业是市场经济中重要的市场主体,其环境守法除了要求环境法律、法规、政策的完善,也有赖于环境执法工作的稳妥开展对企业守法的推动。通过制度和利润两方面分析企业环境守法困境,期望通过环境执法模式的改革,借鉴美国环境执法模式的经验,借助执法理念的变化实现企业自觉的环境守法。     

基于层次分析法的应急物资储备方式研究

科学合理的应急物资储备是有效应对突发事件的重要保障。在综合考虑影响应急物资储备的主要因素的基础上,将应急物资分5类;界定了3类应急物资储备方式;采用层次分析对应急物资的储备方式进行了研究,结果表明,不同类型应急物资的储备方式有较大差别,食品药品类物资应以合同储备和生产能力储备为主;应急救援类物资应以实物储备为主;灾民安置类物资应以实物储备和生产能力储备为主;基础保障类物资应以实物储备和合同储备为主;大型设备类物资主要采用合同储备;从总体上来说,应急物资储备需要采用全面综合储备的方式,而不能偏颇。

Ethological Structure of Freshwater Benthic and Nektobenthic Communities and Its Changes under the Influence of Abiotic and Anthropogenic Factors

Classification of the mode of life and behavior of zoobenthic, nektobenthic, and neustonic organisms was used as a basis for elucidating the formation of ethological structure of their communities in small lakes and streams of northeastern Fennoscandia. It is shown that the general response of these communities to anthropogenic impact is manifested in the reduction of the number of ethological groups. The specific response to eutrophication and heat pollution involves a decrease in the relative biomass of clingers and burrowers and an increase in the biomass of sprawling–walking and wormy animals; the response to toxic pollution and acidification is manifested in the prevalence of sprawlers–walkers.     

Fracture Characterization Using Borehole Radar: Numerical Modeling

Forward modeling of borehole radar data for a series of synthetic discrete-fracture network (DFN) models provides a conceptual framework for interpreting experimental field data at fractured rock sites. A finite-difference time-domain (FDTD) radar wave propagation model was developed for this purpose. Synthetic examples demonstrate the utility of single-hole reflection-mode and cross-hole transmission-mode borehole radar for (1) identification of fracture location and orientation, and (2) identification of fracture pore-fluid properties, which might change as a result of tracer tests or flooding exercises in support of resource development or site remediation. A two-dimensional, synthetic DFN was generated statistically based on hypothetical distributions of fracture length, orientation, aperture, permeability, and inter-connectivity. The DFN includes a zone of permeable fractures embedded within a network of lower-permeability fractures and a low-permeability rock matrix. We modeled the unconnected and non-permeable fractures as being filled with freshwater. To simulate tracer experiments, contaminant releases, or engineered-remediation processes, we considered alternately the inter-connected, permeable fractures to be filled with freshwater air, or saline water (tracer). Synthetic radar data sets for both single-hole reflection and cross-hole transmission modes were generated. The features in synthetic radargrams were then examined and compared to the DFN model to evaluate the likelihood of identifying fracture location, orientation, and pore fluid in field situations. This comparison demonstrates that (1) the replacement of freshwater with saline water in permeable fractures generally increases the amplitude of reflections from permeable, connected fractures; and (2) in general, radar reflection-mode data contains more information about fracture properties than transmission-mode data.
