高职院校实验室资源优化配置与科学管理简

实验室资源优化配置和科学管理是高职院校提高教学、科研水平和人才培养质量的重要途径。当前高职院校实验室资源配置与管理中普遍存在实验室分散封闭管理、资源配置缺乏计划、实验室没有充分利用以及设备缺乏维护保养四个方面问题,针对这些问题应从管理体制改革、设备申报采购制度、实验室潜力开发以及开展培训、提高管理人员水平四个方面来实现实验室合理配置资源、科学规范管理。     

生态城市评价指标体系构建及实证研究

构建了针对秦皇岛市的生态城市评价指标体系,采用多指标综合评价法,对2011年秦皇岛市城市生态化程度进行了评价。结果表明:秦皇岛市城市生态化综合指数为0.687,生态化程度为2级水平,经济持续发展子系统和资源能源节约子系统较为薄弱。根据评价结果,提出了大力发展循环经济、加强水污染治理、提高资源能源利用效率、加大生态建设力度等建议。     

秦皇岛市4种常见绿化植物滞尘效应研究

通过对秦皇岛市4种常见绿化植物的叶片滞尘量、单株滞尘能力及相关因素的研究,发现绿化植物单位叶面积的滞尘量最大可以相差2.5倍左右,树种叶片滞尘能力的大小排序为：国槐＞悬铃木＞金银木＞连翘,单株滞尘能力的大小排序为：悬铃木＞国槐＞金银木＞连翘;绿化植物的滞尘量与环境中粉尘含量成正比,树木滞尘能力还与叶片表面性状、叶面积指数及植物所处环境等因素有关。     

公众参与环境保护制度属性及制度模块构建

民主政治是公众参与制度的出发点和归宿,通过公众的有效参与,环境执法权得到监督;有序是公众参与制度的自然属性,有序才能使参与变得顺畅;利益均衡是公众参与制度的价值准则,环境矛盾最终体现为环境利益和经济利益之争,解决环境纠纷的最佳手段是寻找利益均衡点;政府居于环境执法的主导地位,同时发挥指导、引导、疏导公众和企业的作用;多重沟通平台是公众参与制度的效率保证,政府、企业、公众在执法前后的多重沟通,才能达到参与的最终目标。与公众参与环境执法制度属性相对应的是制度模块建设,如监督制度、程序制度、纠纷调处制度、润性执法制度以及沟通制度等。这些制度既能准确反映公众参与环境执法制度属性,又能完成制度赋予的使命。     

矿区地下水环境影响评价的关键问题探讨

随着人类社会经济的快速发展,地下水环境问题日益严重,由于地下水环境影响具有隐蔽性和滞后性,在矿区建设生产前必须对地下水环境影响进行评价。结合某拟建整合灰岩矿的地下水环境影响评价,进行了实例分析,确定了保护目标、地下水环境影响识别、矿坑涌水量的计算、预测评价方法的选取等关键技术,以期为相似矿区地下水环境影响评价提供参考。     

Hyperautomobility and Governmentality in Auckland

Abstract

A number of cities around the world are associated with very high levels of private motor car usage, and Auckland provides an example of one of these ‘hyperautomobile’ cities. There are many problems with this system of transportation and dependence on the private car, including environmental, social and city design dimensions. Though there is a clear aspiration to move towards reduced levels of car usage in the city's transport and spatial planning strategies, there are major difficulties in implementation terms. We develop and consider future scenarios to 2041 to reduce these levels of motorization, and subsequent transport CO₂ emissions, with a much greater use of public transport, walking and cycling, urban planning, and low emission vehicles. The current implementability of such a ‘sustainable mobility’ future is however questioned in the current political and social context, and critically debated in terms of the available governance mechanisms and the limited attempts to shape the behaviour of the public. We conclude by calling for a reconsideration of the policy measures being considered, including the range and levels of application and investment; with a much wider framing of the transport planning remit, and carried out within a much stronger participatory framework for decision-making.     

Creating False Images: Stream Restoration in an Urban Setting

Stream restoration has become a multibillion dollar business with mixed results as to its efficacy. This case study utilizes pre‐ and post‐monitoring data from restoration projects on an urban stream to assess how well stream conditions, publicly stated project goals, and project implementation align. Our research confirms previous studies showing little communication among academic researchers and restoration practitioners as well as provides further evidence that restoration efforts tend to focus on small‐scale, specific sites without considering broader land use patterns. This study advances our understanding of restoration by documenting that although improving ecological conditions is a stated goal for restoration projects, the implemented measures are not always focused on those issues that are the most ecologically salient. What these projects have accomplished is to protect the built environment and promote positive public perception. We argue that these disconnects among publicized goals for restoration, the implemented features, and actual stream conditions may create a false image of what an ecologically stable stream looks like and therefore perpetuate a false sense of optimism about the feasibility of restoring urban streams.     

A Call for Urgent Monitoring of Food and Water Security Based on Relevant Indicators for the Arctic

This perspective paper argues for an urgent need to monitor a set of 12 concrete, measurable indicators of food and water security in the Arctic over time. Such a quantitative indicator approach may be viewed as representing a reductionist rather than a holistic perspective, but is nevertheless necessary for actually knowing what reality aspects to monitor in order to accurately understand, quantify, and be able to project critical changes to food and water security of both indigenous and non-indigenous people in the Arctic. More relevant indicators may be developed in the future, taking us further toward reconciliation between reductionist and holistic approaches to change assessment and understanding. However, the potential of such further development to improved holistic change assessment is not an argument not to urgently start to monitor and quantify the changes in food and water security indicators that are immediately available and adequate for the Arctic context.     

Environmental Damage,Abandoned Treaties,and Fossil-Fuel Dependence: The Coming Costs of Oil-and-Gas Exploration in the “1002 Area” of the Arctic National Wildlife Refuge

Contrary to claims from American politicians, lobbyists, and oil and gas executives, allowing energy development in the Alaskan Arctic National Wildlife Refuge (ANWR) will harm the environment, compromise international law, erode the social significance of wilderness protection, and ultimately fail to␣increase the energy security of the United States. After exploring a brief history of the ANWR controversy, this piece argues that the operation of oil and gas refineries in ANWR will release discharged solids, drilling waste, and dirty diesel fuel into the ecosystem’s food-chain, as they have from oil operations in Prudhoe Bay. Less obvious but equally important, oil and gas exploration in ANWR will violate a number of international treaties on biodiversity protection. In the end, development in ANWR will threaten the concept of wilderness protection, and will do little to end US dependence on foreign sources of energy. About the Author: Benjamin K.

Sustainable development and the water–energy–food nexus: A perspective on livelihoods

The water–energy–food nexus is being promoted as a conceptual tool for achieving sustainable development. Frameworks for implementing nexus thinking, however, have failed to explicitly or adequately incorporate sustainable livelihoods perspectives. This is counterintuitive given that livelihoods are key to achieving sustainable development. In this paper we present a critical review of nexus approaches and identify potential linkages with sustainable livelihoods theory and practice, to deepen our understanding of the interrelated dynamics between human populations and the natural environment. Building upon this review, we explore the concept of ‘environmental livelihood security’ – which encompasses a balance between natural resource supply and human demand on the environment to promote sustainability – and develop an integrated nexus-livelihoods framework for examining the environmental livelihood security of a system. The outcome is an integrated framework with the capacity to measure and monitor environmental livelihood security of whole systems by accounting for the water, energy and food requisites for livelihoods at multiple spatial scales and institutional levels. We anticipate this holistic approach will not only provide a significant contribution to achieving national and regional sustainable development targets, but will also be effective for promoting equity amongst individuals and communities in local and global development agendas.
