Spatial Structure of Quercus mongolica Forest in Hebei Wuling Mountain Nature Reserve

Abstract

Abstract: With Quercus mongolica in Hebei Wuling mountain as study object and by using mingling degree,neighborhood comparison and uniform angle index,this paper analyzed the spatial structural characteristics of Quercusm ongolica forest in the Reserve.The results showed that Q. m ongolica had the obvious advantage in population density and basal area.The average mingling degree of the forest was 0.299, indicating the simple spatial allocation and poor mixing of different tree species in this plantation.In the spatial structural units,Q.mongolica and J. mandshurica populations were dominant and sub-dominant,accounting for 57% and 64% of the total plants of the populations;As for uniform angle index and the spatial structure units, the spatial pattern of the stands was of aggregative distribution.Stand management in term of the forest ecosystem health should be based on community-based natural succession.

Key words: nature reserve, Quercus mongolica forest, spatial structure, forest ecosystem, Wuling Mountains
