Mainstreaming human and large carnivore coexistence through institutional collaboration

Achieving coexistence between large carnivores and humans in human-dominated landscapes (HDLs) is a key challenge for societies globally. This challenge cannot be adequately met with the current sectoral approaches to HDL governance and an academic community largely dominated by disciplinary sectors. Academia (universities and other research institutions and organizations) should take a more active role in embracing societal challenges around conservation of large carnivores in HDLs by facilitating cross-sectoral cooperation to mainstream coexistence of humans and large carnivores. Drawing on lessons from populated regions of Europe, Asia, and South America with substantial densities of large carnivores, we suggest academia should better embrace the principles and methods of sustainability sciences and create institutional spaces for the implementation of transdisciplinary curricula and projects; reflect on research approaches (i.e., disciplinary, interdisciplinary, or transdisciplinary) they apply and how their outcomes could aid leveraging institutional transformations for mainstreaming; and engage with various institutions and stakeholder groups to create novel institutional structures that can respond to multiple challenges of HDL management and human–large carnivore coexistence. Success in mainstreaming this coexistence in HDL will rest on the ability to think and act cooperatively. Such a conservation achievement, if realized, stands to have far-reaching benefits for people and biodiversity.     

浅谈县级环境监测质量管理工作现状及对策

当前环保系统垂直改革稳步推进,县级环境监测质量管理工作也迎来新的机遇与挑战。从县级环境监测站质量管理工作现状着手,分析新形势下存在质量管理体系有效性缺乏、现场监测过程质量管理薄弱、质量管理意识尚待提高等问题。提出,应从加强体系建设、提高现场监测水平、强化考核培训力度等方面改进县级环境监测质量管理工作水平。     

“Hey Friend,Buy Green”: Social Media Use to Influence Eco-Purchasing Involvement

This study addresses the use of message carriers to convey corporate social responsibility information to promote eco-purchasing involvement. The work tests various media formats transmitted via social media. The effects of corporate vs. peer communication in a corporate social responsibility campaign in stimulating self-reported eco-purchasing involvement are indicated. The research varies communication dimensions of a fictional corporate social responsibility campaign sent through social media. Multiple media formats; new release; article; and advertisement were tested, as was the inclusion of social media persuasive sentiment. The analysis of source/format combinations and source/format/sentiment combinations found statistically significant differences for consumer-to-consumer communication in stimulating eco-purchasing involvement in certain circumstances. This research suggests an emerging role for the consumer communicator as a content co-creator and validates the effective use of articles and news releases instead of advertising on social media, yielding managerial and scholarly implications.     

美国加州南岸地区空气质量监测系统运行管理与借鉴

借鉴加州南岸空气质量监测管理经验（特别是运行管理模式）对于现阶段我国城市环境空气质量监测管理具有极高的参考价值。简要介绍了加州南岸空气质量管理局（ SCAQMD）的空气质量监测现状、监测网络布局、颗粒物采样方法和相关质量管理体系。对现行的环境空气质量指数、管理架构和PM2?5考核方法进行了综合比较，建议从4个方面借鉴SCAQMD经验：试行“空气质量管理区”模式；开展专项研究网络建设；逐步开展手工监测采样和颗粒物化学组分分析；提升数据挖掘水平，服务管理决策。     

渤海湾入海溶解无机氮总量控制研究

基于渤海湾近岸海域的实际调查结果,采取生态物理耦合模型,对渤海湾的主要污染物-溶解无机氮(DIN)的基准环境容量和极小剩余海洋环境容量进行了计算。结果表明,渤海湾DIN的极小剩余海洋环境容量在Ⅰ类和Ⅱ类水质标准下均为负值,渤海湾的DIN已经超标。结合实际的海水功能区水质管理目标,应重点控制非点源的排放,加强上游携带入境污染物的处理,从总量上控制DIN入海污染通量,改善渤海湾水质。     

环境空气质量新标准对郑州和开封空气质量评价的影响

利用河南省环境空气质量新标准实施一期城市(郑州、开封)2013年的环境空气自动监测数据,分析了实施《环境空气质量标准》(GB 3095—2012)对这2个城市空气质量评价的影响。研究发现,若采用新标准,郑州、开封污染物年均浓度超标情况加重;城市空气质量达标率从51%、71%下降到35%和31%,下降了16和40个百分点;PM2.5的纳入是空气质量达标率下降的最主要原因,大于NO2标准的收严和CO、O3纳入评价指标的影响,其超标率分别为58%(郑州)和63%(开封);且PM2.5取代PM10成为郑州、开封的首要污染物,其作为首要污染物的比例均大于70%。     

环境监测生产性及业务创新探讨

探讨了环境监测的生产性问题。监测主体的生产性,即社会化大生产及其排污是环境监测的本源和主体;监测过程的生产性,即环境监测是社会化生产过程;监测价值的生产性,即环境监测价值通过环境监测信息产品的使用价值来实现。针对环境监测业务中逆生产性问题,明确了环境监测业务发展3大方向,即加强污染源监测、发挥环境监测生产能力和提升环境监测信息产品使用价值。提出了创新环境监测站生产方式、发展社会监测力量和加强监测行业监管的建议。     

松花江流域水生态环境质量评价研究

采用生物完整性指数(IBI)法评价松花江流域的水生态环境质量。对25个候选生物参数进行敏感度分析、Pearson相关性分析,最终筛选出由总分类单元数、EPT分类单元数、EPT密度、敏感种分类单元比例、敏感物种数量、Hilsenhoff生物指数(HBI)6个核心参数构成的IBI评价指标。采用95%分位数法建立了IBI评价标准,将IBI评价结果划分为5个等级:大于35.84为优,26.88~35.84为良好,17.92~26.88为一般,8.96~17.92为较差,小于8.96为很差。结果表明,建立的IBI评价方法适用于松花江流域水生态环境质量评价,松花江流域各位点30.0%生物状况为优和良好,23.3%为一般;46.7%为较差和很差,说明流域内近一半区域的水生态质量存在不同程度的受损。流域生境质量主要处于一般-良好的状态;水质处于轻度污染。     

汉丹江(陕西段)水质变化特征分析

基于2008—2012年陕西省境内汉江、丹江干流14个断面的水质监测数据,采用单因子评价法、平均综合污染指数法和秩相关系数法等对该段水体的水质变化特征进行研究。结果表明,汉丹江(陕西段)断面水质以Ⅱ类、Ⅲ类为主,水质总体为优;水质综合污染状况呈下降趋势,其中汉江下降趋势显著;水质综合污染状况空间差异和区域分布特征明显,城区段污染大于郊区,各行政区段河流下游污染大于上游。流域水质主要受有机污染和营养盐因子影响,水体污染源主要来自城镇生活源和农业面源,工业源占比不大且排放行业较为集中。
