Changes of wetland landscape is an essential component of wetland ecology. Study of the temporal and spatial changes of landscape elements provides the scientific foundation for revealing the rule of wetland evolution and carrying out ecological restoration practices. We selected the restored Carex appendiculata tussock wetland in Sun Island as the study area and used 3S technology and filed survey to clarify the characteristics of the spatial and temporal variations in landscape patterns during restoration succession. The area of tussock wetland, expansion rate, shape, number, and morphological characteristics of tussock were determined for analysing the landscape pattern changes of tussock wetland across restoration processes. The results showed that the landscape pattern changed significantly after 8-year restoration:1) The number, height and diameter of tussocks, as well as the plant height and crown width greatly increased (P < 0.05). 2) The area of tussock wetland was increased by about 722 m² with an expansion rate of 48.13%, and the total area of restored tussock wetland reached 2222 m². 3) The combined effect of microtopography and hydrology led to regular expansion in the Carex tussock community. The patch boundary and centroid expanded 29.91 m and migrated 5.9 m to the low-lying southwest, respectively. Additionally, the increasing development (D) and weight of curve boundary (W) indicated that the shape and boundary of a patch tended to be complex, and thus enhancing landscape heterogeneity. 4) Rapid recovery of Carex tussock can be achieved by rhizome reproduction accompanied with water-level regulation.
