The city as a refuge for insect pollinators

Research on urban insect pollinators is changing views on the biological value and ecological importance of cities. The abundance and diversity of native bee species in urban landscapes that are absent in nearby rural lands evidence the biological value and ecological importance of cities and have implications for biodiversity conservation. Lagging behind this revised image of the city are urban conservation programs that historically have invested in education and outreach rather than programs designed to achieve high‐priority species conservation results. We synthesized research on urban bee species diversity and abundance to determine how urban conservation could be repositioned to better align with new views on the ecological importance of urban landscapes. Due to insect pollinators’ relatively small functional requirements—habitat range, life cycle, and nesting behavior—relative to larger mammals, we argue that pollinators put high‐priority and high‐impact urban conservation within reach. In a rapidly urbanizing world, transforming how environmental managers view the city can improve citizen engagement and contribute to the development of more sustainable urbanization.     

When and how to use Q methodology to understand perspectives in conservation research

Understanding human perspectives is critical in a range of conservation contexts, for example, in overcoming conflicts or developing projects that are acceptable to relevant stakeholders. The Q methodology is a unique semiquantitative technique used to explore human perspectives. It has been applied for decades in other disciplines and recently gained traction in conservation. This paper helps researchers assess when Q is useful for a given conservation question and what its use involves. To do so, we explained the steps necessary to conduct a Q study, from the research design to the interpretation of results. We provided recommendations to minimize biases in conducting a Q study, which can affect mostly when designing the study and collecting the data. We conducted a structured literature review of 52 studies to examine in what empirical conservation contexts Q has been used. Most studies were subnational or national cases, but some also address multinational or global questions. We found that Q has been applied to 4 broad types of conservation goals: addressing conflict, devising management alternatives, understanding policy acceptability, and critically reflecting on the values that implicitly influence research and practice. Through these applications, researchers found hidden views, understood opinions in depth and discovered points of consensus that facilitated unlocking difficult disagreements. The Q methodology has a clear procedure but is also flexible, allowing researchers explore long‐term views, or views about items other than statements, such as landscape images. We also found some inconsistencies in applying and, mainly, in reporting Q studies, whereby it was not possible to fully understand how the research was conducted or why some atypical research decisions had been taken in some studies. Accordingly, we suggest a reporting checklist.     

云技术在石油行业应急管理中的思考

面对石油行业突发事件全过程,利用大数据云处理技术,以应急管理4阶段为划分标准,将云技术运用到应急管理四大阶段当中,为解决缺乏合理的信息技术手段、应急信息搜集不全面、数据挖掘分析技术落后、决策支持模型构建不完善等落后的临时性应急管理模式,找寻到一种高效应急管理模式的新方向。     

协同治理理论视角下连云港湾长制试点存在的问题及对策

近岸海域环境综合治理是典型的公共产品和公共服务,需要多个主体协同治理。连云港湾长制已实施两年多,虽取得了一定成效,但从协同治理理论来看,仍存在治理主体相对单一、公众参与不足问题。因此,今后应以协同治理理论为指导,形成多元的治理主体,树立各个治理主体的权威性,加强各治理主体的协同性,充分发挥各治理主体的积极性,共同推进湾长制的实施。     

西北石化区周围毒害类空气污染物污染特征及健康风险评价

采用SUMMA罐、活性炭吸附及玻璃纤维滤膜富集3种方式,于2014年12月对西北地区3个代表性炼化生产基地周围环境空气收集样品,并采用气相色谱-质谱联用、气相色谱法及高效液相色谱法3种方法,对13种典型毒害类物质进行分析,以研究其污染特征和人群健康风险.结果表明,3个石化区周围环境空气中8种毒害类物质普遍检出,检出率超过80%;石化区苯系物、1,3-丁二烯、对二氯苯、苯并[a]芘平均质量浓度范围分别为48.01~182.75μg·m~(-3)、6.28~7.95μg·m~(-3)、5.53~12.62μg·m~(-3)、7.03~36.08 ng·m~(-3).其中,苯并[a]芘超标最为严重,日均浓度超二级标准限值1.8~13.4倍,苯、甲苯、二甲苯也存在不同程度超标现象.3个石化区苯并[a]芘、1,3-丁二烯非致癌健康风险均已超出可接受的风险水平,兰州石化区周围人群遭受苯的非致癌不良影响风险也较高.与此同时,苯、乙苯、苯乙烯、1,3-丁二烯、对二氯苯、苯并[a]芘的致癌风险均超出了可接受的范围,其中苯、1,3-丁二烯、对二氯苯的致癌风险最为显著.

京津冀区域燃煤发电行业大气污染物排放时空变化特征研究

为了科学评估京津冀区域燃煤发电行业特别排放限值和超低排放相关要求实施后的大气污染物减排效果,以行业调查数据为基础,建立了2013年和2015年京津冀区域燃煤发电行业大气污染物排放清单,分析了装机容量与SO_2、NO_x和烟尘排放量的时空耦合关系,讨论了国家相关政策和标准的实施效果。结果显示:区域内2015年燃煤机组装机容量与2013年相比略有下降,SO_2、NO_x和烟尘排放量分别下降75.95%、83.09%和71.20%,减排效果明显。2015年100 MW以下等级机组3种污染物排放总量位居各机组首位,建议通过多种合理方式压减小型燃煤发电机组数量和排放浓度。     

福建省工业CO2排放效率评价研究

运用基于非期望产出、非径向、非角度的SBM-DEA模型,对2005年-2014年福建省工业35个行业CO2排放效率进行评价,然后通过行业效率值动态聚类深入揭示福建省工业行业CO2排放特质,最后提出福建省工业低碳发展的建议.研究表明:福建省工业存在较大的节能减排空间,高效率行业具有技术进步显著的优势,中效率行业效率值受贸易结构影响,低效率行业普遍存在产能过剩的问题.因此,福建省工业低碳转型需要调整能源消费结构、推进低碳技术进步、优化贸易结构、消化过剩产能.
