Considering the characteristics of high salinity landscape water in Tianjin coast area, column experiments were conducted to elucidate the permeability changes of substrate under high salinity environment in the performance of constructed wetland. The effect of particles diameter on permeability of substrate in constructed wetland were identified, and the mathematical model of the correlative relations between the maximum of permeability loss ratio and particles diameter of substrate were analyzed. Results showed that the permeability of constructed wetland´s substrate decreased with runtime until it steadied in some scale, when the permeability was less than initial permeability. In addition, the variety range of permeability coefficient of substrate varied depending on particles diameter. The maximum of permeability loss ratio of different substrates ranged from 60% to 98%, and the correlation between the maximum of permeability loss ratio and particles diameter follows the Guess equation. The particles diameter of substrates made a big different in the change of permeability. The results suggested that particles diameter had great impact on the permeability of substrate for constructed wetland.
