北京市机动车行驶周期的建立方法研究

提出了一种北京市机动车行驶周期的建立方法。行驶周期的确定是建立在准确的行驶工况数据之上的，通过结合使用GPS与OEM两种先进的技术，收集机动车行驶工况数据，为北京市行驶周期的建立提供了新的方法。并通过初步的实路测量试验得到了一个北京市的简易机动车行驶周期，最后与国外的一些著名行驶周期作了对比。

基于资源最优化回收的再制造工程

从对寿命末端产品的处理选择分析出发，建立了末端产品回收梯级模型，提出基于最优化产品末端回收选择的再制造工程回收的附加值最大，环境污染最小，综合效益最高，并分析了再制造在产品全寿命周期各阶段所发挥的重要作用。     

宁夏盐池县社会经济与环境协调发展的策略分析

本文通过分析宁夏盐池县的自然条件、自然资源以及社会经济发展与环境的关系,应用权图影响结构模型对该县社会经济与环境系统进行了定量的分析与研究。建立了7个模型,并通过预测、比较实施不同发展策略后各模型的系统状态,找出了使系统优化运行的灵敏调控点,分析了各分项调整策略之间相互制约、相互促进的关系,提出了使该县社会经济与环境协调发展的策略。     

对废旧物资回收业的管理政策分析

如何从源头做到城市生活垃圾减量化、资源化和无害化，实现物资回收再利用，获得物资回收在经济和环境效益的和谐统一，一直是理论界和现实生活中一个长期争论的问题。从政策管理的角度出发，尝试找到一个实现个人利益和政府管理角色和谐统一的方法，以期能通过政策管理，利用经济手段，从源头实现城市生活垃圾的减量化、资源化和无害化。     

CLIMATE CHANGE AND NATURAL HAZARDS IN NORTHERN CANADA: INTEGRATING INDIGENOUS PERSPECTIVES WITH GOVERNMENT POLICY

A study of the relationship between natural hazards and climate change in the international context provides the background for a discussion of the expected changes. In the context of this global discussion, this paper reviews the current perspectives of those natural hazards that are likely to be influenced by climate change, using northern Canada as a regional case study. The northern implications of the United Nations Framework Convention on Climate Change are examined, including the status of climate change action by the northern territorial governments, the evolving role of indigenous people, and the responsibility for climate change impacts. The difficulties surrounding natural hazards research in remote locations, and the approaches of indigenous people to natural hazards are then presented. The paper concludes with a suggested policy approach for climate change and natural hazards in northern Canada, underscoring the need for more comprehensive adaptive strategies to complement the current tendency to focus on the mitigation of greenhouse gases produced in this region.     

The 'who' and 'what' of training far disaster relief

This paper defines the various levels within government, the voluntary agencies and the community which might benefit from training and makes suggestions as to where the emphasis should be placed. It points out that training programmes should be designed to meet the expressed needs of a particular group of trainees as well as be related to the current or potential disaster situation.     

Counter-disaster training in developing countries

This paper discusses both the need for training within a wider context of community disaster preparedness and the major alternatives in methods of training. Emphasis is placed on the importance of compatibility between the resources within a given country and appropriate training programmes.     

ECONOMIC COSTS AND BENEFITS OF INSTREAM FLOW PROTECTION FOR ENDANGERED SPECIES IN AN INTERNATIONAL BASIN1

ABSTRACT: The U.S. Endangered Species Act (ESA) restricts federal agencies from carrying out actions that jeopardize the continued existence of any endangered species. The U.S. Supreme Court has emphasized that the language of the ESA and its amendments permits few exceptions to the requirement to give endangered species the highest priority. This paper estimates economic costs associated with one measure for increasing instream flows to meet critical habitat requirements of the endangered Rio Grande silvery minnow. Impacts are derived from an integrated regional model of the hydrology, economics, and institutions of the upper Rio Grande Basin in Colorado, New Mexico, Texas, and Mexico. One proposal for providing minimum streamflows to protect the silvery minnow from extinction would provide guaranteed year round streamflows of at least 50 cubic feet per second in the San Acacia reach of the upper Rio Grande. These added flows can be accomplished through reduced surface diversions by New Mexico water users in dry years when flows would otherwise be reduced below the critical level required by the minnow. Based on a 44‐year simulation of future inflows to the basin, we find that some agricultural users suffer damages, but New Mexico water users as a whole do not incur damages from a policy that reduces stream depletions sufficiently to provide habitat for the minnow. The same policy actually benefits downstream users, producing average annual benefits of over $200,000 per year for west Texas agriculture, and over $1 million for El Paso municipal and industrial water users, respectively. Economic impacts of instream flow deliveries for the minnow are highest in drought years.
