    流域生态补偿制度是实现生态文明领域国家治理体系和治理能力现代化的一项重要制度。《中共中央关于全面深化改革若干重大问题的决定》提出,“推动地区间建立横向生态补偿制度”。流域生态资源的跨界性和外部性决定了需要建立上下游政府间利益补偿机制。流域生态利益补偿,即通过协调流域上下游水资源治理的成本和收益分配,目的在于激励保护行为,补偿收益受损方。流域上下游生态补偿机制不健全日益成为目前我国流域治理中政府间争端和冲突的结构性问题,也是流域区际生态利益失衡的主要表现,具体包括各地区生态补偿方法、范围、主体和资金来源等方面的标准不统一,生态补偿纠纷的顶层调解机制不健全。《国家生态文明试验区(福建)实施方案》提...The establishment and perfection of the basin Eco-compensation institution play important roles in promoting the modernization of state governance. Decision of the Central Committee of the Communist Party of China on Some Major Issues Concerning Comprehensively Deepening the Reform indicates that it is necessary to establish the regional horizontal Eco-compensation institution.

    从1987年世界环境与发展委员会(WCED,WorldCommissiononEnvironmentandDevelopment)提出可持续发展的概念以来,国际社会给予了极大关注。当今,可持续发展的思想和原则已得到世界各国的认同,成为指导国家发展的重大指导方针和基本战略。为了实施可持续发展战略,人类需要认真管理人与生态系统之间的关系,需要定量测度发展的可持续性状态。对此,生态足迹模型作为一种生物物理类的度量指标具有独到之处,因而受到学术界、政府组织和非政府组织的广泛认可。中国是一个人口众多,人均资源严重匮乏的发展中国家。有迹象表明,中国的人均生态足迹己经超出其生态承载力。随着经济的发展和人口的...Lots attention has been given to sustainable development since the concept was presented by World Commission on Environment and Development in 1987. Nowadays, the ideas and principles of sustainable development has been widely recognized around the world, and it has become the guideline and basic principles for national development.

    金属纳米粒子是加氢、氧化等反应中的有效催化剂。由于纳米粒子缺乏稳定性,制备分布均匀且稳定存在的金属纳米粒子并不容易。介孔二氧化硅分子筛SBA-15等具有大的比表面,均一的孔道结构,利用其规整纳米空间的限域作用可制备粒径可控的金属纳米粒子。本论文旨在合成限域于SBA-15孔道内的Pd纳米粒子,并将此金属Pd多相催化剂用于以氧气为氧化剂的醇的选择氧化反应。本论文的工作由以下两部分组成:1.限域于介孔分子筛SBA-15孔道内的Pd纳米粒子的合成与表征。采用乙醇萃取法取代高温焙烧法去除SBA-15中的模板剂P123,保留表面的Si-OH,利用[Pd(NH3)4]2+与碱性条件下由Si-OH生成的Si-...Nano-sized metal particles have shown promising applications in heterogeneous catalysis due to their unique catalytic performance. However, size controlled synthesis of nanoparticles remains a challenge since they are thermodynamically susceptible to agglomeration. Mesoporous silica has high surface area and regular pore structure, such as SBA-15. Confining metal particles within the nanospace of ...学位:理学硕士院系专业:化学化工学院化学系_物理化学(含化学物理)学号:20042509

    法院不宜直接受理未经索赔的“保险给付之诉”——兼议保险索赔前置程序之构建

    Get PDF
    保险事故发生后,投保人,被保险人、受益人的保险给付请求没有经过理赔无从确定。当事人未先行向保险人提起索赔而径直提起的诉讼,不符合给付之诉的要件,不是真正意义上的保险给付之诉。应当认识到理赔程序在确定保险给付之债上的重要意义,依据索赔——理赔的保险运作模式,由当事人先向保险人提出索赔从而展开理赔程序确定具体的保险给付义务。我国应规定保险索赔前置程序,明确在保险事故发生后,投保人、被保险人或受益人必须先向保险人索赔(理赔申请),只有当索赔不获满足或有其他争议时才能提起诉讼

    保险事故发生后,投保人、被保险人、受益人的保险给付请求没有经过理赔无从确定,当事人未经先行向保险人提起索赔而径直提起的诉讼因而不符合给付之诉的要件,不是真正意义上的保险给付之诉。依据索赔-理赔的保险运作模式,应当由当事人先向保险人提出索赔从而展开理赔程序确定具体的保险给付义务。我国应规定保险索赔前置程序,明确在保险事故发生后,投保人、被保险人或受益人必须先向保险人索赔(理赔申请),只有当索赔不获满足或有其他争议时才能提起诉讼。The insurance claim won't be able to be determined without settling by the insurer.Thus,the lawsuit for the premium insured brought by the claimant against the insurance company is not a real insurance actio praescriptis verbis for the lack of the elements.The importance of claim settlement for fixing the sum of insurance payment should be acknowledged,and the claimant is obliged to claim directly against the insurer beforehand,following the claiming--settling mode of insurance business rule.It is nessary for China to lay down the insurance claim pre-procedure in legislation,clarifying the obligation that the claimant apply to the insurance company in advance and may bring a suit only when the application is not satisfied

    本文在理性预期假说的基础上,利用上海银行间同业拆借利率(SHIbOr)长短期利率数据,对加入时变风险溢价的利率期限结构进行了实证研究,结果表明:理性预期假说可以解释我国利率市场的预测作用,风险溢价因子为常数时的利率期限结构模型不能解释实际利率数据,而加入经期限修正的风险溢价因子后,利率期限结构模型能够解释长短期利率的预期理论

    文章运用世界自然基金会提供的个人年生态足迹计算软件,通过问卷调查收集资料,测算厦门大学在读学生个人生态足迹,并分析探讨高校在读学生个人生态足迹的组成及影响因素。结果表明,厦门大学在读学生的个人生态足迹介于0.4 gH~1.6 gH之间,平均值为0.83 gH,远低于中国人均生态足迹;在各组成部分中,耕地、水域和碳足迹为主要用地类型,占人均足迹的90%以上;被访者的性别、学科和学历对其个人生态足迹的影响不明显,而个人月可支配收入及其出行方式与个人生态足迹的大小存在明显正相关性,即月可支配收入越高个人足迹越大,选择环保的出行方式则个人生态足迹较小。The paper calculates the personal Ecological Footprint(EF) of the students in Xiamen University(XMU) based on questionnaire formulated by EF calculator of World Wild Fund for Nature(WWF).The constituents and factors affecting personal EF are also analyzed.The results show that the personal EF of students in XMU is 0.4~1.6gh and the average is 0.83gh.Cropland,fishing ground and carbon uptake land are the main land use types for students,accounts for 90% of the personal EF.The personal ecological footprint does not have obvious relations with gender,major and education,but closely relates to personal disposable income and travel mode
