摘　　要：本文对引入鄱阳湖滩涂地营造的中山杉118进行了连续多年耐水淹试验观测。结果表明,淹水时间长短是中山杉118成活的关键,淹水时间越长,中山杉118死亡率越高,极限淹水时间为31 d。在全没顶淹水24 d的条件下,死亡率为11%;在全没顶淹水28 d的条件下,死亡率达64%;在全没顶淹水超31 d的条件下,死亡率高达95%以上,这一结果为中山杉在鄱阳湖滩涂造林地选择提供了理论与实践参考。In this paper,the experimental observation of flood resistance of Taxodium′Zhongshansha′118 introduced into the beach of Poyang Lake has been carried out for many years.The results showed that the water flooded time was the key to the survival of T.′Zhongshansha′118.The longer the flooding time,the higher the mortality of T.′Zhongshansha′118,and the limit flooding time was 31 days.Under the condition of 24 days of total drowning,the mortality was 11%.Under the condition of total drowning for 28 days,the mortality was 64%.Under the condition of no top flooding for more than 31 days,the mortality is more than 95%,the results provide a theoretical and practical reference for the selection of forest land for T.′Zhongshansha′118 in the beach of Poyang Lake.
