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。     

生态经济持续性的度量和趋势预测——以甘肃武威市为例

应用生态占用模型,对武威市生态经济的可持续性进行了评价。对武威的生物资源、能源资源和制成品资源消费的生态占用的计算结果表明,1999年武威市人均占用生物生产性空间为1.589423hm₂,调整后的武威实际生产空间供给为0.856876hm₂/人。1999年武威生态赤字0.73254hm₂/人。对于世界56个国家和地区的人均生态占用和人均GDP数据进行分析,认为二者高度相关。用幂指数模型进行趋势拟合,具有较好的拟合优度和理论一致性。武威生态占用处于强的扩张时期,到2015年,人均生态占用将会达到2.60142hm₂/人,而当年实际生态承载力阈值预测值为1.0657hm₂/人。人均生态赤字扩大到1.5357hm₂/人。生态经济系统的运行是以过度消耗自然资本为代价的。     

建立能够体现化工行业特点的行业排放标准初探

化工行业具有传统的工业类型和新兴产业交叉渗透的特点。现有的污染物排放标准因涵盖行业过多、细化内容不够、可操作性不强、行业特点不突出,故不太适应化工行业的发展,建立新的化工行业污染物排放标准势在必行。文章概要介绍了我国现有污染物排放标准,分析了美国、欧盟、日本、德国等一些国家和组织的排放标准,提议建立能够体现化工行业特点的行业排放标准,以达到淘汰落后工艺和促进清洁工艺的目的。     

环境价值评估方法综述

对目前国内外的环境价值评估方法进行了综述，并提出了一套适合我国国情的价值评估方法，该方法分为１４类２９个指标，作为完善我国环境价值评估体系的一种建议提出。     

循环经济国内外立法研究

二十世纪九十年代以来,由于传统线性经济带来的恶性结果,发展循环经济在国际社会上蔚为风潮.许多西方国家纷纷进行循环经济立法活动,德国和日本建立了较为完善的循环经济法律体系.从西方国家的立法经验我们可以看出,要发展循环经济,建立一个完善的法律保障体系至关重要.我国的循环经济立法还处在初级阶段,要吸收和借鉴先进经验,制定修改一批法律、法规,建立完善的循环经济法律体系,以促进循环经济发展.     

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.
