Community ' s a diversity is measured by simpson diversity index, shannon - wiener diversity index and pielou evenness index. the results show that habitats range in a diminishing sequence of diversity indices from broadleaf forest, broadleaf bush, grassland bush to bamboo forest ; that altitude belts range from 600 - to - 1200 - m belt, under - 600 - m belt to 1200 - to - 1800 - m belt, and no longicorn beetles was found above 1800 m ; months from july, may, june to august, a diversity analysis shows that complicated habitats can hold higher biodiversity
結果表明，不同生境多樣性指數從高到低的順序是：闊葉林、闊葉灌叢、灌草叢、竹林；不同海拔多樣性指數從高到低的順序是： 600 ? 1200m區間、 600m以下區間、 1200 ? 1800m區間， 1800m以上區間暫未發現天牛科昆蟲；不同月份多樣性指數從高到低的順序是： 7月、 5月、 6月、 8月。 -
The results show that season has remarkable effect on component of cerambycidae community, which suggests that longicorn beetles occur much seasonally ; habitat type also has large effect on it, which reflects the dependence of longicorn beetles on host plant ; but altitude gradient has smaller effect on it, which is a result of the fact that longicorn beetles " larvae live all their life inside the stem of host plant and are seldom influenced by outside surroundings
結果表明，月份對天牛群落組成影響顯著，天牛的發生具有明顯的季節性；生境類型對天牛群落組成也有很大影響，體現了天牛對寄主植物的依賴性；海拔對天牛群落組成的影響較小，這與天牛幼蟲終生生活在寄主植物莖內，受外界環境影響較小有關。 -
