In order to understand the flooding tolerance of Taxodium hybrid ‘Zhongshanshan’, we investigated the preserving rate and growth situation of this species in March 2014. The results showed that the average preserving rate of T. hybrid ‘Zhongshanshan’at the 163-174 m elevation was 98.1%, the slope gradient of the hydro-fluctuation belt had a significant effect on the preserving rate, while the original land use type in the hydro-fluctuation belt had no significant effects on the preserving rate. Its average height of trees exceeded 3.5 m, average diameter at breast height (DBH) was larger than 4 cm; the depth of water had no significant effects on the height of trees, but had significant effects on DBH. The gradient of the hydro-fluctuation belt had significant effects on the height of trees and DBH, but the original land use type in the hydro-fluctuation belt had no significant effects on the height of trees and DBH. The strong flooding tolerance of T. hybrid‘Zhongshanshan’lays a solid foundation for improving the Three Gorges Reservoir area in the Yangtze River by biological measures.
