区域(城市)水体中主要有机毒物的筛选

本研究发展了区域(或城市)水体中主要有毒化学品的筛选方法。 在城市下游采集大体积水样,用CH_2Cl_2洗脱,再用有机溶剂萃取,用硅胶柱把有机物分成许多馏分,馏分最终变为水溶液。每个馏分中有机物浓度比原水大1000倍。用这种馏分水溶液进行溞的急性毒性试验和Ames试验。只对毒性大的馏分进行色谱/质谱/数据系统的鉴定和定量分析,然后根据各个化合物的急性毒性、降解难易和“三致”物质的资料及原水样中有机物的浓度资料,就可筛选出一个区域(城市)水体中的主要有毒化学品。     

建设项目实施过程中的可行性研究与环境影响评价

作者根据多年的工作实践，分析了目前建设项目可行性研究与环境影响评价工作中存在的一些问题。提出了编写环境影响评价报告时如何有效地利用建设项目的可行性研究报告文本，以及在没有可行性研究报告的情况下怎样使环境影响评价报告能够准确地反映建设项目的环境问题，进而保证环境影响报告书的质量。总之，恰当处理这两者之间的关系，保证建设项目在建设期与运营期降低与防止建设项目对周边环境影响是本文的主要目的之一。

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.

基于3S的玉溪市土壤侵蚀敏感性评价研究

以玉溪市为研究区域，运用GIS软件对影响土壤侵蚀的因子进行叠加分析，获取玉溪市土壤侵蚀敏感性等级分布图，并与土壤侵蚀现状图加以对比，结果显示：发生土壤侵蚀的地区一定是土壤侵蚀的敏感地区，但土壤侵蚀的敏感地区不一定发生土壤侵蚀：森林覆盖量、质量和人为活动是影响土壤侵蚀的主要原因。
