Abstract:: Based on the aggregation indices and time-specific life table, the structure and dynamics of natural Taxus chinensis population were studied. The results showed that: (1) the natural Taxus chinensis resources distributed sporadically, but they relatively concentrated in the distribution area, and the aggregation class decreased first and then seemed to follow the U-shaped curve in the process of seedling to old trees; (2) the differences of survival amount were significant among the age classes, the survival curve followed the Deevey-Ⅲ type;(3) the mortality was higher at the stage of seedling and sapling, but it declined significantly after Ⅲ level (3 m). These results indicated that the trends of natural Taxus chinensis population were a recession in Funiushan Mountain, high mortality of seedlings caused by harsh environmental sieve might be the main reason for the decline of population, meanwhile lack of resources protection induced the illegal felling trees, habitat destruction and so on also could not be ignored. So it is urgent to take measures to protect and restore the precious resources and to take the strict closure policy and auxiliary measures of artificial breeding.
