Relationships of the dimensions of sustainability as measured by the sustainable society index framework

This article presents a study of the interrelationships between the different dimensions of sustainability as measured by the sustainable society index framework. We examine the statistical relationships between the four indices making up the sustainable society index framework. The analysis uses the complete existing data set provided by Sustainable Society Foundation for the years 2006, 2008, 2010 and 2012 and for 151 countries. While the time period where data are available is quite short, we can make some preliminary observations about the apparent trends in the interrelationships of the different dimensions of sustainability. This study shows that the three dimensions of sustainability are far from all being synergic and positively correlated. There is a strong negative correlation between human well-being and environmental well-being. This is problematic from the point of view of the Brundtland Commission’s three-pillar definition of sustainability. However, the trade-off relationship between economic and environmental development measured by the economic well-being index and environmental well-being index is decreasing and the dimensions are becoming more de-linked. This trend is promising from the sustainability perspective.     

甘肃黄土丘陵地区农户取暖用能需求的评价

甘肃黄土丘陵地区冬季温度多处于0 ℃以下,农户取暖水平低。论文通过实地观测记录获取数据,建立趋势面模型,核算采暖期累计温差和实际用能消耗,提出以16 ℃的室内温度为小康取暖标准。参考国家相关标准,比较实际用能和应用节能技术下用能的热效率。结果表明,陇东长官村和陇中河畔村农户采暖期累计温差分别为23 002 h·℃和36 390 h·℃,实际取暖能耗分别为926 kgce/a和1 199 kgce/a。农户取暖用能数量虽不少,但目前只解决了小康水平下39.6%和46.6%的取暖需求。取暖用能的综合热效率只有17%左右。如果应用节能技术,能耗会大幅降低,提高综合热效率的潜力巨大。因此,通过住房的节能改造和用能设施的改善来提高房屋的保暖性、降低单位面积的热损耗是今后解决取暖用能问题的主要方向。

露天煤矿声环境影响后评估——以胜利一号露天矿为例

本文以胜利一号露天矿为例,在主要噪声源强以及厂界和周边敏感目标的噪声级现状监测的基础上,对煤矿开发后声环境影响进行回顾性分析和验证性评价,结果表明：（1）煤矿四厂界环境噪声昼间和夜间均达到了《工业企业厂界环境噪声排放标准》（GB12348-2008）2类标准限值要求。噪声源中采掘场噪声较大,铁路装车站、铁路专用线以及破碎车间、机修车间、变电所、排水泵站、锅炉房等机修设备噪声源产生的噪声值相对较小。（2）随着煤矿开采量和开采面积的增加,露天煤矿采掘场噪声污染、厂界噪声和周边敏感点噪声会不断加大。而且,采掘场最大噪声级出现的方向也会随着开采方向的推进而变化。（3）验证性分析结果表明,胜利一号露天矿原环评结论较可靠,但预测结果相对偏低,偏低幅度昼间在5.2%-10.7%,夜间在2.4%-13.1%。（4）现状监测和回顾性分析表明,胜利一号露天矿噪声污染不太明显,目前采取的噪声防治措施起到了较好的防治效果。     

长江经济带入境旅游经济时空格局动态性——基于ESDA&GWR法

以5 a为时间间隔，运用ESDA法采用旅游外汇收入平均增长量和平均增长率指标，研究长江经济带126个市域单元2000~2015年入境旅游经济的空间格局演化特征，运用GWR法分析入境旅游经济影响因素的空间异质性。结果表明：（1）长江经济带旅游外汇收入平均增长量莫兰指数经历了 0.164 6~0.164 1~0.057 2的变化趋势，增量相似市域由较强集聚向较弱集聚转化，市域旅游经济增长趋于均衡。一级热点区始终位于江浙沿海市域。一级冷点区由研究区中部向苏北转移，空间范围大大缩小。（2）长江经济带旅游外汇收入平均增长率莫兰指数表现为 0.098 6~0.293 1~0.198 9 的变化趋势，市域之间旅游经济增长关联程度增强，总体差异逐渐缩小。一级冷热点区大幅度转移，同时热点区范围大幅度扩大。后期热点市域数量大大超过冷点市域数量。（3）入境旅游发展较为落后的湖南省、云南省增长速度最快，长三角城市群所属市域始终是入境旅游经济增长最活跃的地区。     

Clarifying values,risk perceptions,and attitudes to resolve or avoid social conflicts in invasive species management

Decision makers and researchers recognize the need to effectively confront the social dimensions and conflicts inherent to invasive species research and management. Yet, despite numerous contentious situations that have arisen, no systematic evaluation of the literature has examined the commonalities in the patterns and types of these emergent social issues. Using social and ecological keywords, we reviewed trends in the social dimensions of invasive species research and management and the sources and potential solutions to problems and conflicts that arise around invasive species. We integrated components of cognitive hierarchy theory and risk perceptions theory to provide a conceptual framework to identify, distinguish, and provide understanding of the driving factors underlying disputes associated with invasive species. In the ISI Web of Science database, we found 15,915 peer‐reviewed publications on biological invasions, 124 of which included social dimensions of this phenomenon. Of these 124, 28 studies described specific contentious situations. Social approaches to biological invasions have emerged largely in the last decade and have focused on both environmental social sciences and resource management. Despite being distributed in a range of journals, these 124 articles were concentrated mostly in ecology and conservation‐oriented outlets. We found that conflicts surrounding invasive species arose based largely on differences in value systems and to a lesser extent stakeholder and decision maker's risk perceptions. To confront or avoid such situations, we suggest integrating the plurality of environmental values into invasive species research and management via structured decision making techniques, which enhance effective risk communication that promotes trust and confidence between stakeholders and decision makers.

Greening up: the effects of environmental standards in EU and US trade agreements

Can environmental provisions in preferential trade agreements (PTAs) foster an environmental race to the top? The ways in which different enforcement mechanisms in North–South PTAs affect the implementation of environmental standards in developing countries are examined. It is argued that environmental provisions in European Union (EU) and United States (US) PTAs will be effective in instigating policy change in partner countries, although the timing of the effect will vary significantly. Fines and sanctions in US PTAs incentivize partner countries to reform during the negotiation process. Reform in EU PTA partners is predicted to occur during agreement implementation as a result of the EU’s policy dialogue approach. Illustrative evidence is provided and the hypotheses are tested using statistical estimations of EU and US PTAs with environmental provisions on developing countries’ environmental policy reform.

主观性在环境侵权案件证据和证明中的作用研究

法院在审理环境侵权案件时,往往依赖于专业鉴定、行政标准、专家意见等等客观依据来确定案件事实.但因为环境问题的复杂性,以及民事主体自身举证能力的限制,经常出现双方举证均不充分,法院无法基于现有事实和证据得出结论的情况.此时,法官应当发挥自身能动性,主动应用主观的、甚至是非科学性的因素和手段,包括容忍义务、经验法则、自由心证等等,这些因素无法被赋予客观的标准,它需要法官基于自身的理性以及经验,结合社会一般观念、习惯等因素进行判断.
