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。

我国辐射环境自动监测系统建设的回顾与展望

辐射环境自动监测是我国辐射环境监测工作的重要内容,是核与辐射安全监管工作的重要手段.本文回顾了“十一五”以来,我国辐射环境自动监测系统建设的进展情况和在核与辐射监管工作中所发挥的作用,总结了辐射环境自动监测系统的建设和运行经验,并对今后的工作进行了展望,提出了完善系统建设和运行的合理化建议.研究指出,作为国家辐射环境监测网的重要组成部分,辐射环境自动监测系统初步具备了对我国省会城市和主要地级城市的辐射环境质量状况的实时监测能力.但由于我国辐射环境自动监测站于2008年底才开始在全国范围内建设,起步较晚、经验不足,依然存在点位数量和代表性不够、自动化程度不够高、软件系统功能不成熟、标准化和规范化问题比较突出,缺乏质量控制技术、运行维护难度大等问题.为此本文提出：第一,增加自动监测站数量,点位布设更有针对性;第二,增加自动监测站的类型;第三,加强软件系统的分析和控制能力;第四,完善相关标准、技术规范和质保体系;第五,完善运行维护体系;第六,增强国际学习和交流.     

港口规划环评评价内容及技术方法探讨

随着经济的快速发展,港口已成为社会发展的重要支柱。但随之带来的是港口建设与环境保护之间的矛盾日益突出,因此必须实施港口规划环境影响评价。本文基于《规划环境影响评价技术导则》(试行),结合港口规划环评的特点,对港口规划环评的技术路线和评价内容进行了总结。评价重点内容从规划协调性分析、环境承载力、公众参与和风险评价四个方面进行了研究和总结,为其它港口总体规划环境影响评价工作提供参考和借鉴。     

Think global,act local: The effect of goal and mindset specificity on willingness to donate to an environmental organization

This paper investigated the effect of goal and mindset specificity on goal-related behavior in the environmental domain. Two studies demonstrated that goal-related behavior was maximized when participants focused on an abstract goal in combination with a specific mindset, or when they focused on a specific goal in combination with an abstract mindset. When goals and mindsets instead matched in terms of abstractness, goal-related behavior was reduced. Study 2 demonstrated that the effect of goal specificity on behavior was mediated by different processes in each of the mindset conditions. When mindsets were abstract, self-efficacy mediated the positive effect of specific goals on behavior; when mindsets were specific, the value of collective environmental action mediated the positive effect of abstract goals on behavior. The results are discussed in the framework of a complementarity approach. It is argued that complementarity of levels of specificity of goals and mindsets may affect behavior particularly strongly in domains where the discrepancy between the abstract and the specific is large (e.g. the environmental domain).

Adsorption selectivity of salicylic acid and 5-sulfosalicylic acid onto hypercrosslinked polymeric adsorbents

Both bottle-point and column-feeding experiments involving different solutes and sorbents were carried out to investigate the adsorption selectivity and separation performance of salicylic acid and 5-sulfosalicylic acid. Their adsorption isotherms onto such hypercrosslinked polymeric adsorbents as NDA-100 and NDA-99 could be well described by the Freundlich equations whose characteristics describe extrathermic and favorable adsorption processes. The adsorption towards NDA-100 mainly depended on the π-π interaction, while that towards NDA-99 was extremely influenced by the static-electric interaction. Additionally, the adsorptive capacity of salicylic acid on NDA-99 decreased while it increased on NDA-100 with the presence of 5-sulfosalicylic acid in the adsorptive environment as the competitive component. Comparatively, the adsorption capacity of 5-sulfosalicylic acid decreased on both resins with salicylic acid as the competitive component. In fact, the difference in the interaction between adsorbent and adsorbate resulted in the straight antagonism on the effective adsorption sites on the adsorbent. In conclusion, the adsorption selectivity of salicylic acid onto NDA-100 was obviously larger than that onto NDA-99 with the existence of 5-sulfosalicylic acid in the adsorptive environment. A satisfactory separation and recovery of tested solutes in aqueous phase could be foreseeably achieved by the sequencing adsorption technique involving NDA-100 as well as NDA-99.
