材料和能源流导向的环境影响评价模型探讨

AN ENVIRONMENTAL IMPACT ASSESSMENT MODEL BASED ON MATERIAL AND ENERGY FLOWS

在分析现有产品环境影响的主要评价方法生命周期评价法相关利弊的基础上,结合材料和能源流导向的环境管理理念推介了较为可行的环境影响评价模型,并就评价模型中指标的建立及相关变量和系数的确定做进一步的探讨,使产品和生产技术的环境影响评价更为简便和客观。

On the basis of analyzing LCA,combining the management thought of material and energy flows,an environmental impact assessment model was introduced.And relative indices in the model were explained subsequently.The indices are used as a basis for determining an integrated index for overall environmental assessment of products and cleaner production technologies.Which can be employed to evaluate environmental nuisance of implemented,modernized and modified products plans and technological processes easily and objectively.
