Abstract:

The spatial distribution patterns and associations of different ages of P. tatarinowii were analysed in Langya Mountain, Anhui Province by O-Ring statistics in point patterns analysis. The results showed that the P.tatrinowii population was of an increasing one, the age class tended to be young ages and the age structure presented a reversedly J-shaped pattern. The age-classⅠexhibited a clumped spatial distribution at the scale of r<25 m. The age-classⅡexhibited a random spatial distribution the others displayed the pattern from random to the well-proportioned distribution with increasing the age-class; The associations of the all different ages showed non-associations except the first and the second age-classes that were positively related at the scale of r>8 m.

Key words: population of Pteroceltis tatarinowii, Langya Mountain, point pattern analysis, spatial distribution pattern, spatial associations
