城市环境质量多层次模糊综合评价法

通过对城市环境质量的指标的综合分析，确定了多层次模糊综合评价方法。该方法通过模糊合成运算将复杂多层次评价问题转化为定量评价，从而更合理有效地分析城市的环境质量状况。     

建设项目景观环境影响评价因素的确定

建设项目对景观的影响应作为环境影响评价的一项内容，在开展该项工作前要确定影响因素。通过各类建设项目对景观环境的影响进行系统的分析和说明，并建立评价的因素体系，对展开建设项目的环境影响评价有一定作用。     

用细胞电泳率指标检测膜毒性物质的探讨

细胞电泳地是近期发展起来的一种检测细胞膜表面微小改变的生物学方法，当膜表面电荷密度分布受影响时，细胞在等强度电场作用下的移动速率会发生改变，根据电泳速率的改变，可以判断外源性物质对细胞膜是否具损伤作用。     

城市级环境信息系统总体方案的研究与开发

在分析我国城市级环境信息现状和需求的基础上,提出了我国城市级环境信息系统的总体方案，系统依靠现有的环境数据和管理软件建立城市环境信息基础数据库，依照数据仓库的组织方式对环境数据重新进行整合，并在此基础上开发出数据查询分析应用和地理信息系统，同时结合城市环保局的办公自动化系统，建立了一个统一的环境信息发布平台，提高了环境信息的共享水平。     

Growth, environment and innovation—a model with production vintages and environmentally oriented research

I develop an innovative environmental new growth model driven by researchers striving for monopoly profits. Skilled labour is allocated between production vintages and two forms of research, ordinary and environmentally oriented. The intermediate sector includes fixed costs and decreasing returns, limiting the number of vintages used. I solve for planner's, laissez-faire, and regulator's solutions, and examine welfare implications and the various distortions in the model (monopoly power, knowledge spillovers, business stealing, environmental externalities). A regulator may wish: (i) to encourage environmentally oriented research; (ii) to concentrate production labour on recent (cleaner) vintages; (iii) to switch labour from production to research. An environmental sales tax may under some circumstances achieve all three—such taxes not only give incentives to reduce pollution, but also shift profits from old vintages to new, thus raising incentives to come up with newer (cleaner) vintages. An environmental tax may even lead to an increase in the rate of production growth.     

A framework based on fuzzy AHP-TOPSIS for prioritizing solutions to overcome the barriers in the implementation of ecodesign practices in SMEs

Small and medium enterprises (SMEs) are under pressure to adopt sustainable practices in their business due to increasing environmental challenges. This study aims to identify and prioritize the solutions to overcome the barriers in the implementation of ecodesign practices in SMEs. This study helps the companies to develop and implement the strategies on priority using higher ranked solutions. In this study, a framework is proposed that is based on fuzzy analytical hierarchy process and fuzzy technique for order preference by similarity to ideal solution to rank the solutions that overcome the barriers in ecodesign implementation in SMEs. The proposed framework is illustrated by conducting a case study of an Indian ring and piston manufacturing company. This framework provides an effective support in the decision-making of the company for producing eco-friendly products through the implementation of ecodesign practices. Results of this study emphasize that training of designers to use different ecodesign tools is an essential practice for SMEs.
