关于加强乌海市工业固体废弃物整治工作的几点思考

乌海市作为资源型城市,加之基础设施不完善,在经济快速发展的同时,产生了工业企业固体废物乱排、乱放、不按规定要求处置的现象,本文针对乌海市工业固废存在的突出问题提出了几点整治的建议。     

餐厨垃圾国家政策及地方法规研究和思考

文章介绍了餐厨垃圾的产生和危害,以及目前国家及地方在餐厨垃圾处理方面颁布和制定的指导性文件、政策性法规、及行业标准。通过总结苏州、宁波、西宁、乌鲁木齐等城市在治理餐厨垃圾过程中的经验,结合这些地区在餐厨垃圾处理方面的地方法规、收集运输系统、无害化处理体系的建立过程,通过分析思考,提出了适用于一般城市的关于餐厨垃圾收集、运输、处理过程系统性的工作框架。指出了餐厨垃圾处理目前面临的主要问题,并对未来如何推进和完善餐厨垃圾处理工作提出了合理化建议,对政府未来的决策具有一定程度的参考意义。     

低碳经济背景下地方政府环境政策执行力调控研究

环境政策执行力与低碳经济发展之间相互促进、相互推动。目前我国已形成较完整的环境政策体系,但在实际执行中并未取得应有的成效。参考国内外已有的地方政府环境政策执行力调控经验,分析环境政策执行力影响因素,从管理体制、诱导制度、监督制度、执行主体自身建设等多个角度提出在低碳经济背景下我国地方政府环境政策执行力调控策略。     

The role of coalitions in disaster policymaking

Disasters have the potential to act as focusing events, which can increase the amount of attention on disaster‐related problems and encourage policy action. Understanding of the political characteristics of disaster policymaking is underdeveloped, yet it is known that these features may be dissimilar to those of non‐disaster policy areas, especially concerning the coalitions of policy actors engaged in the disaster policy process. Coalitions in the realm of disaster policy processes may be less likely to form, may look very different, and may have different goals than those in non‐disaster domains. Knowledge of the emergence, composition, and purpose of coalitions in disaster policy is lacking. This paper draws on prior theory and case observations to define and describe the characteristics of a disaster policy subsystem and to build a typology of coalitions that may appear within such a subsystem, providing a foundation upon which scholars can work to study coalition dynamics in disaster policy subsystems.     

吉林市“白色污染”概况及防治措施建议

“白色污染”是中国城市特有的环境污染。在各种公共场所到处都能看见大量废弃的塑料制品,他们从自然界而来,由人类制造,但是这些废弃的塑料制品最终归于大自然时却不易被自然所消纳,从而严重影响了大自然的生态环境。首先介绍了“白色污染”的概念及其危害;然后对吉林市塑料方便袋的使用情况进行了调查,并以此反映吉林市“白色污染”的概况;最后针对中国当前“白色污染”治理过程中的不足提出了针对性的建议,以期达到能够有效缓解或根治“白色污染”的目的。     

基于主体功能区划的环境政策框架设计

“十一五”时期,国家在区域协调发展上的新亮点就是创新的提出了“主体功能区”概念,主导这一战略决策的实施需要配套各类专项政策。针对环境问题尝试在主体功能区划条件下设计区域差异化的环境政策,整个政策框架遵循区域差异、综合协调、可操控和环境优先四个原则分区域构建,各区环境政策都沿着政策定位、政府作为和重点政策三条思路充分拓展,对于各项环境政策在不同主体功能区实施的力度也进行了详细描述。本政策框架将为深入研究环境政策和启发其他配套政策的研究思路提供一定的参考。     

Low-impact development for impervious surface connectivity mitigation: assessment of directly connected impervious areas (DCIAs)

Urbanization increases directly connected impervious area (DCIA), the impervious area that is hydraulically connected to downstream drainage by closed pipelines. Although the benefits of low-impact development (LID) have been examined in other studies, its effect on alleviating DCIA levels has seldom been assessed. This study measured the DCIA of urban watersheds in Houston, TX, USA. Five land-use types were categorized and the contribution of LID facilities to reducing DCIA in each type was estimated by using Sutherland's equations. The results showed (1) DCIA in commercial areas was greater than that in residential areas, especially for big-box retailers; (2) the percentage of DCIA reduction by LID varied by land-use type; and (3) optimal combinations of LID application could maximize the effectiveness of DCIA reduction. The results contribute to prioritizing land-use type for implementing LID practices and providing local governments with a useful measure to estimate runoff volume.     

Do global climate summits influence public awareness and policy preferences concerning climate change?

A survey-embedded experiment implemented around the time of the 2014 annual Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (N ≈ 1200) examined whether such summits are able to increase citizens’ awareness of climate problems. This study finds that exposure to positive or negative cues about the COP increases climate change awareness, particularly among participants who start out with a low level of awareness. Neither positive nor negative cues about the COP significantly affect people’s policy preferences. Our finding resonates with Bernard Cohen’s observation that the mass media may not often be successful in telling people what to think, but they are successful in telling readers what to think about.     

系统动力学应用于中国区域绿色发展政策仿真的方法学综述

绿色发展是我国"十三五"时期五大发展理念之一,是解决我国发展与保护矛盾的根本途径。系统动力学是模拟宏观社会经济发展趋势和政策效力的常用分析工具,本文对系统动力学在中国区域绿色发展政策仿真中的应用进行了梳理。研究显示:系统动力学应用的区域范围方面,该方法全面应用于从国家直至县域等各个尺度的区域绿色发展研究,区域绿色发展通常被分解为经济、社会、资源、环境等子系统;应用的主要领域方面,水土资源、能源、水环境、固废治理、绿色产业等领域应用较多,大气环境、绿色消费等领域应用相对较少;方法的改进和完善方面,软系统分析法、各类优化方法和地理信息系统与系统动力学的集成应用日益普遍。文末根据文献梳理情况,提出未来应在决策变量设计、历史数据挖掘、环境系统对经济系统的反馈等方面进行方法改进。
