Ancient tea trees are excluded when calculating the species diversity. 古茶园多样性指数的计算未包括古茶树。
The community has an outstanding dominant species and the arborous layer possesses a comparatively high diversity index. 群落的优势种显著，乔木层的物种多样性指数较高，各样地间的植物种类具有一定的相似性。
Using the shortest path distance to replace the distance between two nodes measured by Brownian particles, we present a dissimilarity index algorithm based on the shortest path. 摘要用最短路径距离取代网络中用布朗微粒衡量的两节点之间的距离，在此基础上提出了基于最短路径的相异性指数算法。
