The total length of littoral zone of Lake Taihu is about 405 km, and more than 73% of which is surrounded by dike, other part is closed to hill. Therefore it is a typical dike-type littoral zone. According to different land forms, the littoral zone of Lake Taihu is classified as dike-type, hill-type and estuary-type. Based on the condition of hydrology and wetland area, the diketype is classified as 3 sub-types, namely, permanent-wetland-dike-type, intermittent-wetland-dike-type and non-wetland-diketype. The hill-type is classified as 2 sub-types, namely, wetland-hill-type and non-wetland-hill type. That means total 6 sub-types of littoral zones are defined in Lake Taihu. According to the above classification, several ecological restoration modes and their diagrams are proposed, which adopt different measures, from ecological conservation, ecological restoration to ecological reconstruction. The present research may have some implications for the ecological restoration of other lake littoral zones.
