摘　　要：通过哀牢山自然保护区楚雄州辖区内楚雄市、双柏县、南华县片区中山湿性常绿阔叶林监测样地的调查,对物种结构、物种丰富度与物种多样性指数进行比较分析。结果显示,Shannon Wiener's指数:双柏县(3.453)>南华县(3.350)>楚雄市(3.142);Simpson指数:楚雄市(0.921)>双柏县(0.913)>南华县(0.879);Pielou均匀度指数:双柏县(0.716)>南华县(0.695)>楚雄市(0.652)。综合得出,双柏县片区中山湿性常绿阔叶林的物种多样性比其他两地较为丰富,初步分析原因是双柏县片区的样地气候比其他两地较为炎热,降水适当,更适于物种的发展;同时,3个片区中水青树、野生铁核桃并非中山湿性常绿阔叶林适生树种,但占据一定的生长优势,应该优化林分结构,充分发挥中山湿性常绿阔叶林在涵养水源和物种保护等方面的作用。The monitoring standard sample plots of midddle-mountain moist evergreen broad-leaved forest in Chuxiong City,Shuangbai County and Nanhua County of Ailao Mountain Nature Reserve of Chuxiong are established.Using the comparative analysis of species richness and species diversity index.Shannon Wiener's:Shuangbai County(3.453)>Nanhua County(3.350)>Chuxiong City(3.142);Simpson's:Chuxiong City(0.921)>Shuangbai County(0.913)>Nanhua County(0.879);Pielou Evenness Index:Shuangbai County(0.716)>Nanhua County(0.695)>Chuxiong City(0.652);Concluding that the biodiversity of middle-mountain moist evergreen broad-leaved forest in Shuangbai County is richer than that in other two places.The preliminary analysis shows that the climate of the sample plot in Shuangbai County is hotter than that in other two places,and the precipitation is appropriate,which is more suitable for the development of species;At the same time,Tetracentron sinense and wild iron walnut in the three areas are not suitable tree species for Zhongshan wet evergreen broad-leaved forest,but occupy a certain growth advantage.The stand structure should be optimized to give full play to the role of Zhongshan wet evergreen broad-leaved forest in water conservation and species protection.
