论区域污染治理的经济机制

本文分析了我国区域环境保护面临的困难,指出了造成这些困难的原因主要是地方政府卷入企业过深、区域经济结构中低水平企业比重过大、生产和消费活动中环境滥用普遍等,并提出了在承认环境价值的条件下,建立和完善区域间和区域内环境保护的经济机制的建议。     

The Influence of Synoptic-scale Air Flow and Local Circulation on the Dust Layer Height in the North of the Taklimakan Desert

The present study investigates the influences of synoptic-scale air flows and local wind circulations on the dust layer height (DLH) in the Taklimakan Desert, based on lidar observations performed in the north of the desert in March 2003. The DLH fluctuates approximately every three days between 2500 m (above sea level) and 5000 m, including diurnal variations. Meteorological analyses and numerical simulations show that the three-day fluctuation of DLH corresponds with variations in synoptic-scale air flows over the Taklimakan Desert, and the diurnal variations are linked to downdrafts and updrafts that are formed over the north of the desert as part of local circulations. When strong northerly winds prevail in the upper troposphere and a developed valley wind blows toward the Tienshan Mountains in the lower troposphere, the downdrafts strengthen in the middle troposphere over the north of the desert, lowering the DLH to about 2500 m. In contrast, the DLH rises to about 5000 m when the updrafts develop between strong southerly winds in the upper troposphere and a developed mountain wind blowing from the Tienshan Mountains. Simulations for the local circulation behavior without the presence of the Tienshan Mountains demonstrate that the valley and mountain winds on the southern slope of the Tienshan Mountains control the intensity of the downdrafts and updrafts, thereby influencing the DLH over the north of the Taklimakan Desert.

浅析政府对环境民事诉讼不适当干预

随着我国经济发展，环境污染纠纷在不断增加。由于环境行政法律规范的缺陷和环境行政执法的不力，很多纠纷未能得到及时有效的解决，于是污染受害者不得不求助于环境民事诉讼程序。然而，政府部门对这些诉讼活动的不适当干预引起了一系列严重后果：降低了法律、政府和司法部门的权威性，加剧了环境质量的恶化，严重威胁了公众的生命健康和财产安全，不利于我国法制建设和可持续发展战略目标的实现。文章着重探讨了种种危害后果，并在此基础上分析了政府干预的动机和法院软弱的成因，最后提出了初步的建议。     

畜禽粪污集中处理模式中的三方演化博弈研究——基于规模差异与政府干预视角

作为环境污染治理的新举措,畜禽粪污集中处理中心虽然在高效处理粪污、提高资源利用质量、改善农村环境等方面发挥了显著作用,但是,其在运营中依然存在各种各样的问题,如设备利用率低下、粪污未能得到有效收集、骗取补贴等。为了探讨上述运营困境的形成机理,本文从养殖规模差异化与政府干预视角出发,构建政府、养殖户与处理中心三方共同参与的演化博弈模型,并在不同情境下探讨三方策略选择的影响因素与演化路径。研究表明,当小规模养殖户占比较高时,处理中心会选择“投机”策略加以获利,反之,在粪污处理需求大的规模养殖地区,处理中心则倾向于“不投机”的稳定经营策略;虽然政府补贴对于养殖户选择“参与”策略具有促进作用,但是,对于小规模养殖户而言,仍有一定的概率选择“不参与”策略;政府需要综合考虑处理中心的预期收益、受奖惩力度等因素制定合理补贴范畴,若补贴过高且缺乏相应的监管机制,处理中心会为了谋求更多利益而采取“投机”策略;当处理中心投机行为较频繁时,政府需加大监管并提高惩罚力度,以维护畜禽粪污集中处理模式正常运作。     

Residential environmental evaluation of local cities considering regional characteristic and personal residential preference-a case study of Saga City, Japan

Questionnaire surveys and subjective evaluations on residential environment were performed in order to grasp the main factors of residential environment of small local cities. The suitable evaluation index system was established, and the regional residential environment characteristics and personal residential preference types were analyzed, so that their influence on residential environment evaluation could be grasped. The results can be applied to the residential environment planning, construction and monitoring of local cities.     

Interrupting the balance: reconsidering the complexities of conflict in South Sudan

By the start of 2014, violent conflict had erupted across much of South Sudan following initial violence in Juba on 15 December 2013. The speed with which the fighting has spread raises questions regarding the impact of national‐level politics on violence at the local level. This article develops a framework in which violent conflict can be comprehended as a response to the interruption of the negotiation of the balance of power between groups; the negotiation is interrupted when that balance tips in favour of one group, such as through changes in the national political market or government reforms. The article provides two cases studies of attempts to strengthen the state that inadvertently interrupted local power relations between groups. In response, the groups engaged in violent conflict to reinstate a balance of power. Both examples involve conflict among Dinka groups from 2005 to 2008.     

农村环境治理中的政府责任再论析:元治理视域

当前,我国农村环境问题日益突出。如何实现农村环境的有效治理,学者从不同角度进行了探讨。无论学者如何强调PPP模式的意义、如何强调社会公众以及社会组织的作用,研究最后基本都会指向政府责任。本论文的创新之处就在于重新强调农村环境治理中的政府责任,特别是将其置于元治理视域下进行论析。元治理即治理的治理,元治理并不排斥治理主体的多元化,但更加重视和强调政府在社会治理中的重要性。根据元治理理论,政府在农村环境治理中的责任可以界定为:农村环境治理成本的承担者和多元治理体系的构建者,PPP模式的设计和监督者,社会组织参与治理的支持者和农民参与治理的引导者。当前,农村环境治理中政府责任担当存在的主要问题包括,政府农村环境治理投入不足和治理体系不完善、PPP模式中政府监督责任弱化、对社会组织参与治理的支持不足以及对农民参与治理的引导不够。元治理视域下农村环境治理中政府责任的实现,不仅需要政府承担起最主要治理主体责任,而且需要政府积极引领其他主体参与到农村环境治理中来,形成治理合力。具体而言,应以财政投入增加和多元治理体系构建实现政府最主要主体责任,同时,政府应以监督责任强化为重点保障PPP模式实施,以发展能力提升积极支持社会组织参与,以环境意识和制度信任水平提高等引导农民参与。     

About bridges and bonds: community responses to the 2000 floods in Mabalane district, Mozambique

Massive floods hit Mozambique in 2000.1 Many of the affected regions benefited from external aid. This paper investigates how the floods impacted on two communities in the interior of the Limpopo Valley, which did not receive significant assistance during the event and in the immediate aftermath. Drawing on the livelihood approach, it focuses on the role of two types of local resources: knowledge and social capital. The paper shows that the scale of the 2000 floods surpassed the response capacity of these resources and looks at how wealth and gender influenced access by households to the local support mechanisms that enhance survival and recovery. It appears that the floods mainly affected wealthier households, as these more frequently lost houses and cattle. The paper points to the importance of ploughs and cattle for local support mechanisms, which, in turn, most likely reduced the capacities of communities to recover from the disaster.
