Abstract: The key technical difficulty of ecological restoration in dry-hot valley reservoirs lies in screening plants with strong flooding and drought tolerance. We present the potential tendency of plant community succession in water-level-fluctuating zone of Wudongde reservoir area based on vegetation investigations in Wudongde, Xiluodu and Three Gorges reservoir areas as well as related researches, climatic conditions and water fluctuation rhythm. In consideration of natural and artificial restoration, native and exotic plants, we selected the plants for ecological restoration in water-level fluctuating zone of Wudongde reservoir area, and propose the vegetation arrangement along altitude gradient. The middle and lower altitudes of water-level fluctuating zone are equipped with herbs inclusive of Cynodon dactylon, Cyperus rotundus, Hemarthria altissima, Abutilon theophrasti, Setaria glauca and Digitaria sanguinalis, and the upper is arranged with trees including Albizia julibrissin, Taxodium‘Zhongshanshan', Betula nigra, Morus alba and Salix variegates, and a quantity of herbaceous plants.
