  2. The results shows that the community richness, species diversity indices and evenness of tree layer and shrub layer share the same order, of which is higher in pure limestone region than that of in pure dolomite region, but it reverse in herb layer ; the coefficient of similarity is considerably low between all plots, while species turnover rate is quite high among the plots and is higher in dolomite region than that of in limestone ; in different karst regions, karst processing leads to niches diversity characterized by special morphologies and special element geochamical features, and therefore affect the dynamic and features of plant communities

    我們在最有代表性之一的貴州茂蘭喀斯特森林保護區選取純灰巖和純白雲巖兩種巖性的喀斯特環境，對其元素地球化學特徵及其中原生性植物群落的相異性和物種多樣性進行了對比，結果發現：不同巖性區域多樣性：喬木層和灌木層為純灰巖區純白雲巖區，草本層為純白雲巖區純灰巖區，總體上純灰巖區的高於純白雲巖區的；各樣地間的相似性系數都很低，相同巖性類型內的明顯高於不同巖性類型之間的相似度；物種周轉率高，且白雲巖區高於石灰巖區，種類組成差異明顯；喀斯特區可溶巖地球化學背景通過喀斯特作用導致特殊的地形條件與元素地球化學特徵，並引起局部小生境的分異從而影響植物群落特徵。
  3. Community similarity is measured by sorenson coefficient and cluster analysis is used at the same time. the results show that similarity between habitats is slightly low
