摘要(Abstract)：

针对陕西省环境污染治理问题,采用基于网格的树形层次化排放清单编制方法,建立2015年陕西省与分城市VOCs人为源高分辨率排放清单,从而研究VOCs的排放分布特征.首先,采用排放因子法计算陕西省和分城市VOCs排放量;然后,比较选取合适权重因子分配VOCs月排放量,以研究时间分布特征;最后,根据所得数据绘制出1 km×1 km的空间网格分布,并得出分析结果.结果表明:陕西省VOCs排放总量为92.91×10⁴t,其中化石燃料燃烧、生物质燃烧、工艺过程源、溶剂使用量、移动源和储存与运输源的排放量分别为1.87×104t,其中化石燃料燃烧、生物质燃烧、工艺过程源、溶剂使用量、移动源和储存与运输源的排放量分别为1.87×10⁴,11.43×104,11.43×10⁴,29.94×104,29.94×10⁴,15.32×104,15.32×10⁴,21.86×104,21.86×10⁴,12.49×104,12.49×10⁴t,工艺过程源为最大的排放源,占比为32.22%;分城市VOCs排放量对比分析,最大的为西安市,其次为咸阳市和榆林市;根据陕西省时空分布图分析,污染排放集中于关中地区,且6月份为全年VOCs排放量的最高峰.
