研究了中国多氯联苯(PCBs)的生产和使用情况,利用中国人口数据作为替代数据,编制了中国PCBs精度为1/6°纬度×1/4°经度网格的使用清单,使用MapInfo地理信息系统软件绘制了中国PCBs使用清单分配图.中国PCBs从东到西的使用比例是东部:中部:西部=45.2:35.7:1 9.1.中国PCBs的使用主要集中在中部和东部工业发达、人口密集的地区;在96～130°E,20～50°N区域内使用量最多.

Chinese product and usage of Polychlorinated Biphenyls (PCBs) were studied. In order to allocate PCB usage in a grid system with a 1/6° latitude by 1/4° longitude resolution, gridded Chinese population distribution on the same grid system in 1982 was used as surrogate, and a map was produced to show the gridded total PCB usage from 1965 to 1974 in China by using a Geographic Information System (GIS) software MapInfo. The ratio of PCB usage in China is East:Middle:West =45.2:35.7:19. 1. The usage of Chinese PCBs focuses on the eastern part of the country with highly developed industry and large population. The area with the largest PCBs usage in China was in the region ranged 96 ～ 130°E longitude and 20～50°N latitude.
