Abstract: To comprehensively understand the variation of Nyssa sinensis population in Sanming City,the space time method and smoothing technique were used in life table analysis.Results showed that diameter at breast height (DBH)structure of N.sinensis population is at temporal stability.The peak of mortality rate and vanishing rate both appeared at the age of 3-4 and 8 years,respectively.The survival curve can be described by Deevey-Ⅱtype.Four function curve of survival exhibited that N.sinensis population decreased at young stage and grew stably at mature stage and old stage.The results can provide a scientific basis for the management of N.sinensis population.

Key words: Nyssa sinensis, DBH structure, life table, survival analysis
