为了解茂兰喀斯特森林溪流水生昆虫的群落组成与特征，对其3条溪流中水生昆虫进行采集、鉴定，并分析了水生昆虫群落组成、结构、特征和 ETP 昆虫季节变化。结果表明：共采集到水生昆虫4256个，分别隶属于7目34科，其中，蜉蝣目、！翅目、毛翅目和鞘翅目为四大优势类群，个体数量占水生昆虫总数量的82．07％；干排溪流中水生昆虫个体数量最多，占总数的53．55％，板寨溪流次之（31．71％），尧兰溪流最少（14．74％）；ETP昆虫的个体数量最多，占水生昆虫总数的69．48％；干排溪流水生昆虫群落优势度最高，而水生昆虫群落多样性和均匀性都较小。
為瞭解茂蘭喀斯特森林溪流水生昆蟲的群落組成與特徵，對其3條溪流中水生昆蟲進行採集、鑒定，併分析瞭水生昆蟲群落組成、結構、特徵和 ETP 昆蟲季節變化。結果錶明：共採集到水生昆蟲4256箇，分彆隸屬于7目34科，其中，蜉蝣目、！翅目、毛翅目和鞘翅目為四大優勢類群，箇體數量佔水生昆蟲總數量的82．07％；榦排溪流中水生昆蟲箇體數量最多，佔總數的53．55％，闆寨溪流次之（31．71％），堯蘭溪流最少（14．74％）；ETP昆蟲的箇體數量最多，佔水生昆蟲總數的69．48％；榦排溪流水生昆蟲群落優勢度最高，而水生昆蟲群落多樣性和均勻性都較小。

To explore the community composition and features of aquatic insects in Maolan karst forest rivulets,the community composition, structure, features and ETP insect seasonal change of aquatic insects,which were collected and identified from three rivulets,were analyzed.The results showed that totally 4 256 aquatic insect individuals were collected and identified to 34 families,seven orders. Trichoptera,Ephemeroptera,Plecoptera and Coleoptera were dominant groups,accounting for 82.07% of all the aquatic insects collected.Most aquatic insects were found in Ganpai rivulet in Maolan karst forest, accounting for 5 3 .5 5% of the total,much more than that found in Banzhai rivulet(3 1 .7 1%),and the least were found in Yaolan rivulet(14.74%).The number of individual ETP insects was the most,accounting for 69.48% of the total number of aquatic insects;the dominance of Ganpai rivulet insect communities was the highest,and aquatic insect community diversity and evenness were smaller.
