本文介绍了一种实用的方法，网站依赖的生命周期分析（SDLCA），区分网站依赖的环境影响，从系统的过程，考虑每个过程的地理条件。这种方法通过使用场地相关特征因子（SDCF）将环境输出转换为其影响。这种方法定义了一个地区的影响等效（IMPACT）的空间区域内的地理系统的边界内，在站点依赖的生命周期清单（SDLCI）分析和计算的环境输出的SAME的过程。每个区域代表一组地理区域，这些区域内部具有相同的环境影响，可以使用地理信息系统绘制地图。根据SAME准备SDLCI和SDCF有助于SDLCA的实施，因为在SDLCI期间允许使用较少的区域。为了证明可持续发展方法的应用，制定了一个具体影响强度;它通过SDCF的投入产出分析，根据一个部门的单位活动直接和间接地量化影响。使用SAME的SDLCA的有效性证明通过两个案例研究：一个研究悬浮颗粒物，和一个研究苯。在这两种情况下，撞击强度的计算使用的方法和结果进行了比较，与那些网站通用的LCI。
This paper describes a practical approach to site-dependent life-cycle analysis (SDLCA) that differentiates site-dependent environmental impacts from a system's processes by considering the geographical conditions of each process. This approach converts an environmental output into its impacts by using site-dependent characterization factors (SDCFs). This approach defines an area-the Spatial Area of iMpact Equivalency (SAME)-within the boundaries of the geographical system during site-dependent life-cycle inventory (SDLCI) analysis and calculates an environmental output from a process for the SAMEs. Each SAME represents a collection of geographical areas with internally homogeneous environmental impacts and can be mapped using a geographic information system. Preparing a SDLCI and SDCFs based on SAMEs facilitates the implementation of SDLCA by permitting the use of fewer regions during SDLCI. To demonstrate application of the SAME approach, an embodied impact intensity was formulated; it quantifies the impact directly and indirectly on the basis of the unit activity of a sector by means of input-output analysis with SDCFs. The validity of using SAMEs for SDLCA is demonstrated through two case studies: one studying suspended particulate matter, and one studying benzene. In both cases, the impact intensities are calculated using the SAME approach and the results are compared with those of site-generic LCI.
