相似系数

Examples
- Coefficient of similarity = no . of shared genera ( species ) between kunyu mountain and other mountains ( except cosmopolitan ) / no . of genera ( species ) in kunyu mountain ( except cosmopolitan )
相似性系数=甲、乙两地共有属数（种数） （不包括世界分布属） /甲地属数（种数） （不包括世界分布属） 13 。 - 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
我们在最有代表性之一的贵州茂兰喀斯特森林保护区选取纯灰岩和纯白云岩两种岩性的喀斯特环境，对其元素地球化学特征及其中原生性植物群落的相异性和物种多样性进行了对比，结果发现：不同岩性区域多样性：乔木层和灌木层为纯灰岩区纯白云岩区，草本层为纯白云岩区纯灰岩区，总体上纯灰岩区的高于纯白云岩区的；各样地间的相似性系数都很低，相同岩性类型内的明显高于不同岩性类型之间的相似度；物种周转率高，且白云岩区高于石灰岩区，种类组成差异明显；喀斯特区可溶岩地球化学背景通过喀斯特作用导致特殊的地形条件与元素地球化学特征，并引起局部小生境的分异从而影响植物群落特征。 - On comparing the composition of its flora with some neighbouring floras , gmnr is most similar to lianhua mountain and dinghu mountain , the representative flora of the " southern subtropical region " . the tropical elements in gmnr flora are obviously less than those in the jianfengling flora which is the " northern tropic region " , and the temperate ones less than those in the lushan mountain flora and the jiulong mountain flora , the representative flora of the " middle subtropical region " . as shown by the coefficient of similarity of flora and the clustering analysis of geographical elements , gmnr flora has a close relationship with others in guangdong , such as the flora of lianhua mountain , dinghu mountain , qimuzhang and chebaling , and the influences of tropic elements on those flora become less and less with the latitude ' s increase
本文通过区系相似性系数比较和地理成分聚类分析，认为古兜山与莲花山、鼎湖山、七目樟和车八岭植物区系的联系都很密切，广东植物区系受热带成分的影响有从低纬向高纬、由沿海到内陆逐渐降低的趋势：古兜山植物区系受热带成分入侵最为强烈，莲花山和鼎湖山受热带成分的影响有所降低，七目樟植物区系受热带成分的影响进一步降低，车八岭植物区系受热带成分的影响最弱。
