俄罗斯环境管理问题所引发的法律思考

对俄罗斯的环境管理观念，相关环境法律规定的生态化要求，联邦及联邦各主体两级关系协调化以及环境管理手段的经济化与多样化倾向等问题作了着重分析，并鉴于中俄在历史上社会与经济制度的关联性及正处经济转轨的共同性，希望通过比较中俄两国在历史和现实发展中存在的异同与联系，以求能为我国进一步的环境管理立法提供借鉴性的思考。     

生态农业发展与小城镇建设

以3家生态村为例说明乡镇企业在生态农业产值中占据主导地位。通过对乡镇企业的经济效益、环境效益和社会效益以及小城镇发展的优越性分析可知，乡镇企业不宜在农村发展，应该在小城镇中发展，农村生态建设要立足农业，通过减少土地的人口承载量，提高劳动生产率和增加农民收入。

废弃混凝土的开发利用

混凝土仍将是21世纪一种应用最广泛的建筑材料，但越来越多的拆除建筑物会产生大量的废弃混凝土块，既带来环境污染，又造成资源浪费。搞好废旧混凝土的开发利用，具有明显的环境效益和经济效益。     

新农药环境化学行为研究(V)-—三氟羧草醚(Acifluorfen)在土壤和水环境中的滞留、转化

从如下几方面研究了三氟羧草醚在土壤－水环境中的化学行为：一是土壤对该药的吸附，结果表明，吸附强度与土壤理化特性密切相关，Ｆｒｅｕｎｄｌｉｃｈ常数ｋｆ＝０．９４Ｗｏｍ＋０．６５Ｗｃｌａｙ－９．５９ｐＨ（ｒ＾２＝０．９４）；二是吸附机理研究，发现三氟羧草醚能与碱金属以外的许多金属离子形成配合物，并证实了与ＣＵ＾２＋形成的双核桥联合物的可能性；三是实验指出它在水中避光有一定的稳定性，不易水解；四是它在〈     

2019年西安首场雾霾PM2.5关键特征的综合诊断

通过对WRF-Chem（Weather Research and Forecasting Model Coupled to Chemistry）环境模式模拟资料、HYSPLIT（HYbrid Single Particle Lagrangian Integrated Trajectory Model）前/后向气团轨迹资料、环境站监测资料，以及西安理工大学（Xi''an University of Technology，简称XUT）多波长激光雷达、米散射激光雷达、能见度仪、粒谱仪等观测资料的综合诊断，探讨了2019年1月初发生在西安的雾霾过程（记为首场雾霾）PM_2.5组分、分布及传输特征，旨在为雾霾气溶胶研究提供有益的个例积累.定性、定量双重检验表明，Chem模式较成功复制了此次雾霾气溶胶过程.利用这些可靠的模式数据分析表明，PM_2.5中碳气溶胶的主要组分为有机碳，约占85%，强盛期气溶胶各组分随高度增加均呈递减趋势，各组分近地面浓度最高.通过对两类不同方法获取的消光系数对比分析表明，相比于模式数据，激光雷达数据具有更高的垂直分辨率，因此，更善于描述消光廓线的细节特征.通过对多源资料的综合诊断最终揭示出，"北风涌"是雾霾消散的关键影响因子，沿铜川-西安-山阳一带存在着污染物传输的重要路径，雾霾由此体现出自北向南依次消散的特征.     

Fisheries management: integrating societal preference, decision analysis, and ecological risk assessment

Fisheries management is the practice of analyzing and selecting options to maintain or alter the structure, dynamics, and interaction of habitat, aquatic biota, and man to achieve human goals and objectives. The theory of fisheries management is: managers or decision makers attempt to maximize renewable `output' from an aquatic resource by choosing from among a set of decision options and applying a set of actions that generate an array of outputs. Outputs may be defined as a tangible catch, a fishing experience, an existence value, or anything else produced or supported by renewable aquatic resources. Overall output is always a mix of tangible and intangible elements. However defined, management goals and objectives are essential components of fisheries management or any other field of renewable natural resource management. Reaching consensus on management goals and objectives has never been a simple task. Beyond the broad and often conflicting goals of an agency, managers must decide who should set specific management objectives — agency personnel, the public, or a combination of the two. Historically, rhetoric aside, fisheries managers in North America nearly always have consulted with professionals in governmental roles to set management objectives. In a strongly pluralistic society, this often resulted in protracted political and legal conflict. Increasingly, there are calls for use of risk assessment to help solve such ecological policy and management problems commonly encountered in fisheries management. The basic concepts of ecological risk assessment may be simple, but the jargon and details are not. Risk assessment (and similar analytical tools) is a concept that has evoked strong reactions whenever it has been used. In spite of the difficulties of defining problems and setting management objectives for complex ecological policy questions, use of risk assessment to help solve ecological problems is widely supported. Ecological risk assessment will be most useful (and objective) in political deliberations when the policy debate revolves around largely technical concerns. To the extent that risk assessment forces policy debate and disagreement toward fundamental differences rather than superficial ones, it will be useful in decision making.
