基于AHP法白洋淀湿地生态评价

以白洋淀湿地为研究对象,采用层次分析法对湿地进行生态评价.结果表明:湿地最主要的功能是生态服务功能(0.64);其次是生态保护功能(0.26);最次是资源功能(0.1).单项指标中最重要的是缓洪滞沥功能(0.31),最次为土地资源功能(0.004).最后,通过计算湿地综合评价指数(CEI=0.58),根据自然保护区生态...     

On sustainability and social welfare

This paper proposes to define sustainability in terms of leaving it possible for future generations to sustain certain defined targets. It is shown that variants of genuine savings and the ecological footprint can then serve as indicators of sustainability. The link between sustainability and intergenerational welfare is examined, and it is shown how to incorporate indicators of sustainability into a social welfare measure, including risk in the analysis.     

落实《水污染防治行动计划》投融资思路与建议——对《水污染防治行动计划》的解读

创新、拓宽水环境保护领域投融资渠道,是落实水污染防治行动计划、保障国家水安全的关键环节。研究结论表明,水污染防治领域成熟稳定的财政资金投入机制匮乏、中小环保企业水环境治理项目融资存在制约瓶颈、社会资本水污染治理投入盈利机制不健全等是关键制约因素。鉴于此,文章提出了落实《水污染防治行动计划》的投融资思路和具体建议:整合设立水污染防治专项资金以建立政府常态化投入机制,设立政府主导的环境保护基金以发挥财政资金引导作用,建立社会资本水污染防治项目资金投入回报机制以吸引社会资本投入,创新环境金融服务、发挥市场融资作用以提升水污染治理企业或项目融资能力。     

汽车经销商的绿色行为模式及其绩效评价研究

汽车经销商既是汽车销售者,也是提供汽车维修、保养和二手车翻新的服务商。本文以汽车经销商的绿色行为模式为研究对象,探讨经销商在日常运营过程中的绿色行为,根据相关的方法和理论指导,结合对汽车经销商绿色行为管理及绩效评估的实践,构建经销商的绿色绩效综合评价体系。主机厂可以根据评价结果,有针对性地制定提升经销商绿色度的方案。     

基于DEMATEL-ISM的地下金属矿山人机系统事故影响因素分析

针对地下金属矿山人机系统的复杂性和动态性,基于人、机、环境、管理和信息5类事故致因,充分考虑各个因素之间的交互作用,确定地下金属矿山人机系统安全的15个重要影响因素,结合决策实验室分析法和解释结构模型对影响因素进行处理和分析,实现影响因素的层次划分。结果表明:人机系统中,人员各方面的知识更新慢和认知缺陷是根本原因;安全文化薄弱和非功能性交互是深层次原因;不确定性、信息交互受阻和系统结构脆性属于过渡致因;人为失误、人机约束失效、重复或遗漏控制、物质交互受阻、能量交互受阻和应变能力差是事故的近邻致因;机械物理部件失效和无事故事件通报对金属矿山人机系统安全性的影响相对较弱。     

Understanding the social impacts of enforcement activities on illegal wildlife trade in China

Illegal wildlife trade enforcement is a cornerstone conservation strategy worldwide, yet we have a limited understanding on its social impacts. Using Chinese online wildlife seizure news (2003–2018), we evaluated the interactions among enforcement operations, news frequency, and social engagement (i.e., whistle-blowing) frequency. Our results showed that intensive enforcement operations, which commenced after 2012, have social impacts by increasing the frequency of all seizure news significantly by 28% [95% Confidence Interval (CI): 5%, 51%] and those via whistle-blowing by 24% [95% CI: 2%, 45%], when compared to counterfactual models where possible confounding factors were accounted for. Furthermore, we revealed the potential interaction between enforcement seizure news with and without social engagement, and the consequential social feedback process. Of the species identified from ‘whistle-blowing’ news, up to 28% are considered as high conservation priorities. Overall, we expanded our understanding of the enforcement impacts to social dimensions, which could contribute to improving the cost-effectiveness of such conservation efforts.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01686-9.
