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 dike-type is classified as 3 sub-types, namely, permanent-wetland-dike-type, intermittent-wetland-dike-tvpe and non-wetland-dike-type. 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.%太湖湖滨带岸线总长405 km,73％以上被防洪大堤所包围,其余部分临近山体,属于典型的大堤型湖滨带.按照湖滨带地形地貌分为大堤型、山坡型、河口型三类,根据水文条件和露滩情况,又将大堤型分为长期露滩、间歇露滩、无滩地型,山坡型分为有滩地型、无滩地型,形成6种类型的湖滨带.根据以上太湖湖滨带划分类型,结合湖滨带生境,气候、水文条件以及植被分布现状等因素,分别采取生态保育、生态修复、生态重建的对策,设计了不同类型的太湖湖滨带生态修复模式,并分别提供了形象的修复模式示意图,以期为太湖及其类似湖滨带的生态修复提供一定的借鉴.
