Abstract

In this study, the characteristics of stand structure and spatial distribution of Quercus liaotungensis forest in Liupan Mts. were analyzed based on the forestry resources inventory data collected in 2005. It was showed that Quercus liaotungensis forest is mainly distributed in the sites with an elevation of 1 900-2 300 m, an aspect of semi-shady, semi-sunny and shady slope, and a slope gradient of 20-35°. The sites with Quercus liaotungensis forest were very close with those occupied by Populus davidiana forests. The existing stands of Quercus liaotungensis were young forests, with an age of 30 years in average. The stand density was large with the average of 1 046 trees·hm-2. The mean tree height was 7.8 m, and the mean DBH was 12.4 cm. The trees with a DBH of 5-10 cm accounted for more than 50% of the total. With the increasing elevation, the change of aspect from semi-shady to shady and to semi-sunny slope, the variation of slope position from upper part to lower part, both the density and DBH and height of trees increased. These are mainly due to the forest age increase. As key accompanying pioneer tree species in the Quercus liaotungensis forest, the amount of Populus davidiana decreased when increasing forest age. This demonstrated that the existing Quercus liaotungensis forest is in the process of progressive succession. Thus, the close-to-nature management was suggested to promote the right development of current Quercus liaotungensis forests to the direction of close-to-nature forest stand.
