摘　　要：采用修改过的CanMETOP模型,修正过的2005年1o(经度)×1o(纬度)精度网格的γ-HCH残留清单作为模型的输入数据,计算了2005年全球大气中γ-HCH的浓度.2005年全球土壤残留为13600t,其中印度、中国、原苏联以及欧洲(去除原苏联)4个区域的土壤残留量占全球γ–HCH总残留量的72%.选取已发表的与研究区域相关的3组2005年的大气γ-HCH的监测浓度与其相对应的模拟结果进行对比,结果显示这3组数据具有很好的相关性,验证了γ-HCH残留清单的准确性和修改后的模型的有效性。A modified CanMETOP model from a regional scale to a global scale was used to simulate the atmospheric transport of γ-HCH world-wide with a global gridded 7-HCH soil residue inventory for 2005 on a 1° longitude by 1° latitude resolution （approximately 100 krn by 100 km） as model input. The total γ-HCH residues in global soil in 2005 was 13600t, 72% of which were in the soil of the four regions, including India, China, the former Soviet Union （FSU）, and Europe （excluding the FSU）. The modeled air concentrations was evaluated by monitoring data published by different research groups, and a good correlation between the monitoring and modeled data validated the good quality of the γ-HCH soil residue inventory and the effectiveness of the modified model as well.
