城市尺度VOCs污染源排放清单编制方法的构建

 基于国内外文献调研和北京市VOCs污染源普查结果,总结出一套较为完整的城市尺度VOCs污染源排放清单编制方法,该方法概括VOCs污染源排放清单的编制范围、各类VOCs污染源排放量的估算方法、VOCs污染源的空间定位方法和不确定性分析方法.同时较为全面地分析了各类污染源排放清单建立过程中,需要使用的排放因子和排放模型,需要收集的活动水平数据、相关模型参数及其获取途径,可以为研究者和环境管理部门建立排放清单提供指导.

Establishment of emission inventory compiling methods for VOCs pollutant sources in city scale

In this paper, a relatively complete set of inventory compiling method for VOCs pollutant sources on city scale is put forward based on the study of domestic and abroad documents and the general investigation result of VOCs pollutant sources in Beijing as well. The method summarizes the inventory contents, the estimated methods for sorted VOCs pollutant sources emission, the spatialization of VOCs sources and the uncertainty analysis for the method. Meanwhile, the related elements for the establishment of the sorted VOCs sources emission inventory are also comprehensively analyzed, such as the used emission model, factors, parameters, the activity level of the VOCs sources and the appropriate acquisition measures. This paper could provide advices for researchers and environmental authorities on the establishment of VOCs emission inventory.
