用循环经济理论指导工业区环境影响评价

区域开发的不确定性等给区域开发的环境影响评价(REIA)提出了较高的要求。循环经济按照自然生态学的原理,形成"资源-产品-消费-再生资源"的物质闭循环的流动过程。融入循环经济理念,将弥补传统区域开发环境影响评价模式的不足,更好发挥其在项目审批及环境管理中的作用。     

A comparative analysis of predictors of sense of place dimensions: attachment to, dependence on, and identification with lakeshore properties

Sense of place can be conceived as a multidimensional construct representing beliefs, emotions and behavioural commitments concerning a particular geographic setting. This view, grounded in attitude theory, can better reveal complex relationships between the experience of a place and attributes of that place than approaches that do not differentiate cognitive, affective and conative domains. Shoreline property owners (N=290) in northern Wisconsin were surveyed about their sense of place for their lakeshore properties. A predictive model comprising owners' age, length of ownership, participation in recreational activities, days spent on the property, extent of property development, and perceptions of environmental features, was employed to explain the variation in dimensions of sense of place. In general, the results supported a multidimensional approach to sense of place in a context where there were moderate to high correlations among the three place dimensions. Perceptions of environmental features were the biggest predictors of place dimensions, with owners' perceptions of lake importance varying in explanatory power across place dimensions.     

Applying Integrated Urban Water Management Concepts: A Review of Australian Experience

This article explores recent Australian experiences in the application of the concept of integrated urban water management (IUWM) to land development sites through the review of 15 case studies. It discusses lUWM’s emergence and comments on the success or otherwise of Australian experience in its application. The understanding of IUWM is maturing within the Australian water industry, an occurrence that has been facilitated by demonstration sites such as those reviewed. Successes include the translation of IUWM concepts into well-functioning operational urban developments, significant reductions in the impact of the urban developments on the total water cycle, and the increasing acceptance of the concept within the water and land development industries. However, there is still room for greater integration of the water supply, stormwater, and wastewater components of the urban water cycle, improved dissemination of knowledge, enhancement of skills in both public and private organisations, and monitoring the performance of systems and technologies.

经济与环境协调发展综合指标与实证分析

贯彻落实科学发展观,其重要内容之一就是要实现经济与环境的协调发展.建立了体现经济与环境协调关系的5个单项指标,即能耗强度、水耗强度、污染物(SO2和COD)排放强度、运输强度、环保投入强度,以及1个综合性指标--经济与环境协调度.以上述指标为基础,比较分析了代表我国东部及中、西部地区经济发展水平的广东省、湖北省和陕西省1999-2003年经济与环境关系现状.结果表明:东部发达地区经济与环境日趋协调,而中、西部地区经济与环境关系协调度较差,尤其是西部地区表现尤为明显.      

水环境退化经济损失的计量方法及其应用

水环境退化较难以市场价格方式体现,是绿色GDP核算的一大难点.分析了影响水环境退化的社会经济因素、自然因素,在此基础上,构建了水环境退化的计量模型,并将社会经济发展的阶段性特征、水资源供需矛盾、降水补给变异特征和水质状况纳入模型中,采用不同参数进行描述,以保证模型的逻辑完备性和计算的简洁性.在湖州市绿色GDP核算过程中,采用该模型分别计算各县区2001-2004年水环境退化的经济损失.这些损失与当地水资源供需矛盾、水污染状况、社会经济发展等因素变化状况相符,准确反映了湖州市水环境退化的实际状况.结果表明,水环境退化的经济损失,除水污染程度外,还受到社会经济因素和降水补给等自然因素的影响.      

上海市“十四五”规划绿色发展驱动因素研究

本文首次以上海市“十四五”规划的视角,使用系统动力学方法研究上海市的绿色发展因素。首先确定了由经济、社会、环境、资源四个子系统交叉融合而构成上海市绿色发展系统,再基于系统动力学原理和上海市2012—2019年的数据构建上海市绿色发展模型,响应“十四五”规划在绿色发展方面设立的目标,构建多个未来发展情景并进行指标参数调控,依据各个情景的仿真结果,分析并总结了“十四五”规划背景下上海市的绿色发展特点。研究结果表明,影响绿色发展的关键因素由主到次依次为生态环境建设支出、研发支出、产业结构调整。相比于产业的投资结构调整,上海市对从业人员结构的调整可以高效平衡经济与环境的发展;加快科技创新可以在很大程度上抑制碳排放,从而快速实现上海市的“双碳”目标;针对化学污染物的治理,污染源防治不但十分有效,而且有利于持续性发展,这些措施应是上海市政府的首选。     

辽宁团山海蚀地貌自然保护区选划研究

根据2003年11月辽宁团山海蚀地貌自然保护区选划研究现场调查,探讨了该区海蚀地貌的成因,评价了海域环境质量和生物多样性,依据海洋自然保护区类型与级别划分原则(GBT17504-1998),确定了保护区类型,并采用定性与定量相结合方法给出了保护区级别。结果表明,保护区海域环境质量总体尚好,生态群落正常,保护区类型符合《海洋自然保护区分类原则》(类别III)相关标准,主要保护对象为海蚀地貌景观,该保护区可建成国家级,这在全国沿海尚不多见。
