%X In Huoshan Qiliyu woodland, a field survey was made on the typical <em>Pinus tabulaeformis</em>, and the distribution of <em>P.tabulaeformis</em> at different age-classes and its co-relationship were studied. The results show that: (1)The distribution of the age-classes appears kurtosis, i.e. the majority is the middle-aged, 20-30 cm, whereas the numbers of young and old are comparatively less; (2)The spatial distribution of these seven age-classes tends to be in groups, in which ages 4, 5 and 6 are more obvious. Meanwhile, it centralizes in groups in small-scale and tend to be in random distribution in large-scale; (3)The co-relationship between different age-classes is significantly positive correlated, of which ages from 3 to 5 are more significant. This significantly positive correlation is beneficial for the <em>P.tabulaeformis</em> to make full use of the resources in order to guarantee the living and development of the groups.
