| 摘 要： | An investigation was conducted on distribution pattern, site condition and population structure of yew Taxus cuspidata Sieb. et Zucc. in Muling Forest Bureau of Heilongjiang Province, China in April, 2005. Results showed that yew is mainly distributed under the main storey of natural mixed forest of conifer and broadleaf, the soil moisture content of the yew site is high （40%-60%）, the pH value of soil is relatively lower （4.7-5.5）, and that the population structure of wild yew is not rational, belonging to the degeneration population, which is one of the reasons leading to the population decline. Although the site conditions of Muling area are suitable for the growth of wild yew, the population of wild yew shows a decline tendency, due to the fact that the middle-sized adult yew trees have been cut, young yews are often grazed by wildlife, and that the trunks of adult yew tend to be hollow.

| Abstract: | An investigation was conducted on distribution pattern, site condition and population structure of yew Taxus cuspidata Sieb. et Zucc. in Muling Forest Bureau of Heilongjiang Province, China in April, 2005. Results showed that yew is mainly
distributed under the main storey of natural mixed forest of conifer and broadleaf, the soil moisture content of the yew site
is high (40%–60%), the pH value of soil is relatively lower (4.7–5.5), and that the population structure of wild yew is not
rational, belonging to the degeneration population, which is one of the reasons leading to the population decline. Although
the site conditions of Muling area are suitable for the growth of wild yew, the population of wild yew shows a decline tendency,
due to the fact that the middle-sized adult yew trees have been cut, young yews are often grazed by wildlife, and that the
trunks of adult yew tend to be hollow.
