Aiming at providing basic information on dust capturing capacity of different herbs, this paper selected 15 kinds of herbs which widely used on the Baima Road of Fuzhou City, using the filter method with varied filtrated membranes, measured and calculated total particulate matter, particles diameter less than 10 μm and particles diameter less than 2.5 μm per unit leaf area, and combined with leaf structure to analysis the dust retention mechanism. Test results showed that there were significant difference among particle retention ability of different herbs while the maximum was over 3 times of the minimum, Ophiopogon japonicus dustfall absorbing capacity was the highest in a level of 3.0838 g·m-2 while that of Musa basjoo was the lowest in a level of 0.7405 g·m-2 . The dustfalls on the leaf of 15 herb plants were mainly fine particles, the leaf surface structure directly affects particle retention ability of plants.
