The situation of intercepted weeds from wooI in Jiangsu port during 2004 to 2012 was introduced in this paper, and the corresponding countermeasures were then proposed. The resuIts showed that a total of 38 famiIies, 138 genera, 268 species and 13 868 species-times of weeds were intercepted, incIuding 3 famiIies, 11 genera, 20 species and 2 094 species-times of quarantine weeds. The weeds were intercepted from the wooI introduced from 19 countries and regions, among which, Australia had the highest species-times, accounting for 71.0% of the total. Bases on the analysis of interception situation of weeds, some countermeasures were pro-posed from the perspectives of risk assessment, quarantine supervision, quarantine treatment and epidemic surveiI ance, providing some reference for estabIishing a perfect system for preventing the invasion of exotic weeds.
