The diversity and evenness of bud-habiting fungi decrease with the crown down.

树栖真菌多样性与均匀度越高，病害发生的可能性越低，呈负相关。

The Shannon index,Margalef index,and Pielou evenness index were 1.63,3.36,and 0.35,respectively.

Shannon指数、Margalef丰富度指数和Pielou均匀度指数的平均值分别为1.63、3.36和0.35。

Due to human disturbance,the species in Dakouhe River were far less than that in Wangzi Island area. However,the evenness index decreased from east to west in both areas.

由于人类活动的干扰程度不同,大口河地区物种数远低于汪子岛地区,同时,沿从西往东方向,两地区群落物种分布的均匀性逐渐减少。

The result shows that spinnability of cotton banana fibre blended yarn could be improved,blended yarn strength could be increased,yarn evenness and hairiness could be improved by chemical modification treatment on banana fibre before spinning and adjusting spinning processing properly.

结果表明:在纺纱前对香蕉纤维进行化学改性处理并适当调整纺纱工艺有助于提高棉纤维香蕉纤维混纺纱的可纺性能,提高成纱强力,改善成纱条干和毛羽。
