Taking Cunninghamia lanceolata coppice forest in Longquan County, Zhejiang Province as research object, the spatial structure of the forest were investigated and analyzed by using uniform angle index, neighborhood comparison and mingling degree. The results indicated that the stand uniform angle index was 0.512, the pattern of tree distribution was random, the pattern of tree distribution of the C. lanceolata was cluster distribution, the pattern of tree distribution of the Schima superba was randomm, the pattern of tree distribution of the other species was uniform. The stand average mingling degree was 0.438 4, being a weak mixed plantation to moderate mixed plantation. The neighborhood comparison order was Castanopsis sclerophylla, Pinus massoniana > Cunninghamia lanceolata > Cinnamomum camphora > Schima superba > Liquidambar formosana, Ormosia hosiei > Alniphyllum fortunei > Ulmus pumila. In order to improve plantation quality and paly its function better, this study aimed to provide scientific basis for guiding selective cutting management, replanting native tree species and spatial structure optimization of Cunninghamia lanceolata coppice forest. ©, 2015, Chinese Academy of Forestry.
