Abstract: In this paper, three parameters were considered to be the suitable ones to describe stand spatial structure completely. The first one was mingling, which could be used to analyze the spatial distribution and isolation of species in the stands. The second one was neighborhood comparison, which could be used to characterize the size differentiation of trees. The third was neighborhood pattern, which could be used to describe the distribution of tree positions. The three parameters were used together in analyzing and describing spatial structure of Korean pine broad leaved forest. When using the distribution and the mean of mingling to analyze the spatial collocation of species in the stands, the authors could conclude that mingling intensity of most stands were middling and the most intensive. Tree position distribution was analyzed by using the mean and the distribution of neighborhood pattern.It was concluded that random distribution was the main spatial characteristics of most stand. After using neighborhood comparison and mingling to analyze spatial characteristic of main species, the authors could also consider that the combination of two parameters could be described the spatial characteristic of species clearly.
