Ancient tea trees are excluded when calculating the species diversity. 古茶園多樣性指數的計算未包括古茶樹(shù)。
The community has an outstanding dominant species and the arborous layer possesses a comparatively high diversity index. 群落的優(yōu)勢種顯著(zhù)，喬木層的物種多樣性指數較高，各樣地間的植物種類(lèi)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. 摘要用最短路徑距離取代網(wǎng)絡(luò )中用布朗微粒衡量的兩節點(diǎn)之間的距離，在此基礎上提出了基于最短路徑的相異性指數算法。
