Physical model experiment with 1:10 model scale is taken to test the wave absorbing effect with vegetation on east-breakwater in Tianjin center fishing port.The vegetation arrangement,trees rows and submerged depth are considered to analyze the absorbing ability of the vegetation.The results show that：1) the vegetation can reduce the wave height and overtopping water within a limited scope of wave height;2) as the absorbing effect,rectangular arrangement is better than the quincuncial one;half-submerged water depth is better than the all-submerged and the more planted rows the better for wave absorbing;3) for the project of Tianjin center fishing port,the maximum rate is 32.9% for wave height decrease and 87.8% for overtopping water decrease with 7 rows trees on the breakwater shoulder.
