对高黎贡山中山湿性常绿阔叶林树种结构及多样性特征进行了研究。结果表明，高黎贡山中山湿性常绿阔叶林动态监测样地中树种以单叶、革质、全缘、中型叶为主，群落外貌以常绿的中高位芽植物为主，落叶树种较少，群落季相变化不明显。群落中树种数、树木个体数分别在H＜5 m高度级及1 cm≤DBH＜5 cm胸径级最多，并随高度或胸径的增加而不断减少，这种变化趋势可用直线函数或负指数函数来较好地拟合。胸高断面积的最大值分别出现在11 m≤H＜14 m高度级和20 cm≤DBH＜25 cm胸径级。群落中共有95个树种，10546株树木， Shannon－Weiner指数为1．716， Simpson指数为0．014，均匀度指数为0．867，在整体上表现出较高的物种多样性水平。树种丰富度、树木个体数及Shannon－Weiner 指数随树高度和胸径级的增加而逐渐下降， Simpson指数、均匀度指数则呈相反的趋势。与国内其它样地相比，高黎贡山样地中的树种丰富度、单位面积内的树木个体数、单位面积内的胸高断面积等都处于较居中的位置，稀有种所占比例在各样地中较低，而样地中最大重要值的大小在各样地中最小，显示出较丰富的物种多样性。

Structural characteristics and diversity of the tree species in the mid-montane humid ever-green broad-leaved forest in the Gaoligong Mountains in Yunnan Province were studied .The results showed that the forest is characterized by evergreen mesophanerophytes with simple and leathery and entire mesophylls , having a few decid-uous trees in the canopy layer and an unconspicuous seasonal aspect .In the plot , the species richness and the a-bundance are most among trees with height <5 m or with 1 cm≤DBH<5 cm, and decreased with the increase of the height or DBH class, respectively, which can be fitted very well with linear function or negative exponential function.The basal area are largest among trees with 11 m≤H<14 m or with 20 cm≤DBH<25 cm.In the plot, there were 10 546 individuals in 95 species, and ite Shannon-Weiner indes is 1.716, its Simpson index is 0.014, and its evenness index is 0.867 , indicating a higher level of species diversity in the whole .The species richness , the abundance and the Shannon-Weiner index were decreased gradually with the increase of the height and DBH class, but the Simpson index and the evenness index showed the opposite trend .Compared with other domestic plots, the species richness , density, basal area per ha of Gaoligongshan plot were at the middle level , but the maximum importance value was the lowest , and the proportion of the rare species was only higher than one plot , showing a higher diversity among these plots .
