克拉玛依市水,土资源承载力与城市发展对策研究

在城市可持续发展的进程中，克拉玛依已具备了许多有利条件，但同时也存在一些限制性２。文章重点研究了克拉玛依水、土地资源的承载力与城市发展的关系，从水资源供需平衡，水资源承载力与城市发展规模控制、土地资源人口承载力、工业用地规模、居住用地规模、绿化用地规模和环境管理等方面提出了对策。     

The application of life cycle assessment to design

This paper explores the practical application of life cycle assessment (LCA) to product system development. While life cycle assessment methods have been studied and demonstrated extensively over the last two decades, their application to product design and development has not been critically addressed. Many organizational and operational factors limit the integration of the three LCA components (inventory analysis, impact assessment and improvement assessment) with product development. Design of the product system can be considered a synthesis of individual decisions and choices made by the design team, which ultimately shape the system's environmental profile. The environmental goal of life cycle design is to minimize the aggregate environmental impacts associated with the product system. Appropriate environmental information must be supplied to decision makers throughout each stage of the development process to achieve this goal. LCA can serve as a source of this information, but informational requirements can vary as the design moves from its conceptual phase, where many design choices are possible, to its detailed design and implementation. Streamlined approaches and other tools, such as design checklists, are essential. The practical use of this tool in product development also depends on the nature and complexity of the product system (e.g. new vs. established), the product development cycle (time-to-market constraints), availability of technical and financial resources, and the design approach (integrated vs. serial). These factors will influence the role and scope of LCA in product development. Effective communication and evaluation of environmental information and the integration of this information with cost, performance, cultural and legal criteria will also be critical to the success of design initiatives based on the life cycle framework. An overview of several of these design initiatives will be presented.

西江沿岸地带工业资源开发策略

西江沿岸地带是一个工业不发达的待开发民族区域,但它拥有多方面工业资源优势,而且工业开发环境条件良好。作者认为,优势的工业资源开发必须在全方位开放与资源深度利用的基础上以轻型为主导的策略,重点建设制糖、水果加工、水电、有色金属为主的原材料及加工等若干工业基地。布局上以西江干流和区内铁路干线为“轴”,结合重点工业“点”,稳定提高中部,重点开发东部,创造条件开发西部,实现“点轴结合,逐步推进”的工业资源区域开发策略。     

生态农业建设中的水资源生命周期及系统功能响应

论文从生命周期角度，对原先自然环境恶劣、通过生态农业建设取得了良好效果的3个生态农业县的水资源利用进行了全过程研究。结果表明，水资源生命周期过程的进展情况受多种因素影响。目前，各生态农业县水资源生命周期过程仍处在发育的初级阶段。这一过程的完整性与系统生态、经济和社会功能的提高成正比。
