一种基于事故后果的重大危险源安全规划方法

介绍了一种基于事故后果的重大危险源安全规划方法。该方法详细阐述了“最坏”事故情景选择、事故后果阈值确定及后果伤害范围划分的方法,以危险源周边人群作为主要脆弱性目标,通过分析事故后果伤害范围和目标的脆弱性级别确定危险源与周边环境的兼容性。另外,以危险品仓储区为例,利用该方法对仓储区可能发生的事故后果影响范围进行计算,对仓储区选址的可行性进行分析。本文提出的重大危险源安全规划方法可为城市土地使用及危险源的安全规划提供参考。     

Spatial distribution of aerosol pollution based on MODIS data over Beijing, China

With the help of regression analysis,the relationships were detected between aerosol's contribution to apparent reflectance(ACR) derived from Moderate Resolution Imaging Spectroradiometer(MODIS)on board Terra and hourly PM_(10)mass concentration measured at 30 ground-based locations in Beijing for the August of 2003 and 2004.It was shown that there was a good correlation between the ACR and PM_(10)(linear correlation coefficient,R=0.56).On the basis of this relationship,spatial distribution and possible sources of PM_(10)derived from MODIS were analyzed and two frequently heavily-polluted regions were found,namely downtown of the city and the district near Xishan Mountain.These two regions coincidently are also urban heat island centers.The foundings of this paper will be greatly useful for environmental monitoring and urban planning for Beijing,especially for the 2008 Olympic game to be held in Beijing.     

旅游地的类生命特征研究

把旅游地视为一个特殊生命体和特殊的生态系统．旅游地与生物体存在非常类似的机理。具有旅游地生命周期、旅游地生态系统、旅游地之间存在诸如共生、竞争、寄生、捕食生态空间关系等明显的类生命特征。研究旅游地的类生命特征．为运用生态学理论研究旅游发展问题提供了可靠依据和切实可行性,为更好地解释和透视旅游发展问题实质提供了崭新的途径与思路,生态学理论在旅游中的应用和解决旅游问题具有现实的可能性和潜在的应用价值,在丰富旅游学与生态学理论的同时,指导并促进旅游业的可持续发展。     

矿产资源规划理论的形成和发展

矿产资源规划是区域发展规划的重要组成部分,是政府对矿业经济进行宏观调控的一种手段。本文从理论更新和完善的角度重新确立了区域矿产资源规划的理论体系,提出矿产资源规划理论经历形成、发展与创新三个阶段,并就矿产资源配置与价格规律、矿产资源经济区划理论和可持续发展理论在其中的深远影响进行了初步探讨。     

Footprints for Sustainability: The Next Steps

The concept of an ecological footprint is based on the understanding that every individual human appropriates a share of the productive and assimilative capacity of the biosphere. An ecological footprint corresponds to this exclusive biologically productive area that a defined population uses for all its resource requirements and wastes, and is expressed in terms of bioproductive space, with world-average productivity. Humanity's footprint or its aggregate ecological demand can only temporarily exceed the productive and assimilative capacity of the biosphere without liquidating and weakening the natural capital on which humanity depends fundamentally. Therefore, accounting tools for quantifying humanity's use of nature are essential for overall assessments of human impact as well as for planning specific steps towards a sustainable future.This paper discusses the strengths and weaknesses of the ecological footprint as an ecological accounting method, points out research needs for improvement of the analysis, and suggests potential new applications. The paper identifies ten new applications of the tool to make it applicable at various geographic scales and for a number of analytical and didactic purposes. Then nine methodological improvements are suggested that could refine the currently applied method, making assessments more sensitive to a larger number of ecological impacts. It concludes that many crucial questions pertinent to building a sustainable society can be addressed by current ecological footprint research. By making the method more complete, this tool could evolve from being largely of pedagogical use to become a strategic tool for policy analysis.     

A spatially explicit backcasting approach for sustainable land-use planning

General backcasting as a decision support and planning method starts from desired future states and simulates developments backwards until reaching the present state. Development pathways that reveal steps to be taken to reach a certain future state, and milestones that serve as interim goals, are created during the process. Backcasting has hitherto only been applied in workshops or as a theoretical framework and no spatially explicit backcasting model has previously been established. This paper presents the development of a spatially explicit backcasting model. The proposed model first creates a future scenario utilizing an agent-based model and then simulates backwards. It is implemented using the programming language Python. The model has been applied to a case study for sustainable land-use planning in Salzburg, Austria. The results of the model run show a successful backcasting of land-use classes from a future state back to the present, in 10 year time steps.     

Measuring the linkage between strategies on sustainability and institutional forces: an empirical study of Spanish universities

Policy documents are commonly identified as key outcomes that guide initiatives directed by senior university leaders towards sustainability through plans and policies. Many studies have called for a more integration of sustainability into universities. Nevertheless, the interest in sustainability issues has been more recent in the specific case of Spain. This study analyses the strategic plans developed by Spanish universities in the last decade with two different aims: first, we examine the extent to which Spanish universities are incorporating strategies on sustainability. The second goal evaluates whether the presence of strategies on sustainability in Spanish universities could be associated with coercive and mimetic pressures. Findings indicate the low presence of strategies on sustainability in Spanish universities. Moreover, the results seem to suggest that the presence of strategies on sustainability in Spanish universities could be linked with coercive and mimetic pressures emanating from the State performance funding for universities. The results indicate that universities usually incorporate practices and strategies on sustainability as a response of the pressure exerted by institutional forces, such as the funding systems of higher education institutions.
