摘要
以江西德兴典型阔叶树林分为研究对象,应用主成分分析对不同林分生境质量状况进行比较。结果表明:不同林分类型阔叶林生态系统质量评价结果依次为:米槠+甜槠林(0.72)>甜槠+木荷林(0.34)>马尾松+木荷林(0.24)>丝栗栲+石栎林(0.23)>拟赤杨+马尾松林(0.07)>石栎+甜槠林(-0.53)>丝栗栲+木荷林(-1.07)。在江西德兴地区常绿阔叶林生境质量较优为米槠+甜槠林分和甜槠+木荷林分,较好林分为马尾松+木荷及丝栗栲+石栎群落。
Evergreen Broad-leaved Forest in Dexing Area of Jiangxi Province was selected as the research object, the paper evaluated the quality of different stand by using the principal component analysis. The results showed that habitats range in a diminishing sequence of stand quality indiced from the forest of Castanopsis carlesii and C. eyrei（0.72）, the forest of C. eyrei and Schima superba（0.34）, the forest of Pinus massoniana and S. superba（0.24）, the forest of C. fargesii and Lithocarpus glaber（0.23）, the forest of Alniphyllum fortunei and P. massoniana（0.07）, the forest of C. eyrei and L. glaber（-0.53） to the forest of C. fargesii and S. superba（-1.07）. The forest of C. eyrei and C. carlesii, and the forest of C. eyrei and S. superba in Dexing City of Jiangxi Province are better habitat quality of evergreen broad-leaf forest, the forest of P. massoniana and S.superba（0.24）, the forest of C. fargesii and L. glaber and the forest of A. fortunei and P. massoniana come second.
