The community structure characteristics of natural mixed Yunnan Pine (Pinus yunnanensis) forests were studied in Diaolinshan Natural Reserve, Middle Yunnan Plateau. The results indicated that mean DBH of all trees and Yunnan Pine, and the densities of all large trees (DBH≥30 cm) and Yunnan Pine showed significant differences on various soils and were in the order of dark-red soil>yellow-red soil>red soil. The stumpage densities of all trees and Yunnan Pine indicated significant differences on various soils and those on red soil ranked the top one. As for total basal areas of all trees and the percentage of Yunnan Pine’s basal areas, they indicated significant differences on various soils and presented the tendency of dark-red soil>red soil>yellow-red soil for the former and just the reverse for the latter. The coverage of herb layer showed significant differences on various soils and those on dark-red soil and yellow-red soil were remarkably higher than that on red soil. The forest was divided into 4 layers on dark-red soil but only 3 layers on yellow-red soil and red soil. Individual DBH distributions of tree layers showed a typical reverse "J" shape. Except that very few individuals of P. armandi, Lithocarpus leucostachyus and Ternstroemia gymnanthera distributed in the size class of DBH≥40 cm on dark-red soil, almost all individuals occupied the size class of DBH≥30 cm with Yunnan Pine. Main tree species of DBHleucostachyus, T. gymnanthera and Ilex polyneura, whereas on yellow-red soil and red soil were Keteleeria evelyniana, Cyclobalanopsis delavayi, Quercus acutissima and Q. aliena. Population structure of Yunnan Pine was characterized as constant type on dark-red soil and red soils, but was featured as recessionary type on yellow-red soil. Keteleeria evelyniana,C. delavayi, Q. aliena and Castanopsis delavayi on red soil featured as interim population type, and other main tree species on dark-red and yellow-red soils characterized as constant or incremental population types.
