| 摘 要： | 应用典范对应分析（CCA）对长白山北坡静水水体12个样点中28种水甲虫与环境关系的研究表明，长白山5种环境因子中水底腐殖化程度和海拔对水甲虫的分布起主要作用，与排序轴的相关系灵敏分别高达0.8371和0.7206，而水温和植被密度也有较大的影响，在环境因子的影响下不同生境中水甲虫分布的种群不同，深刻斜凹龙虱，端钩切眼龙虱，布朗沟牙甲，沼梭科水甲虫等主要分布在深水区，与水温没有关系。而异毛龙虱和舟型牙甲等与海拔和水泡子的腐殖化程度呈正相关。

| Abstract: | The relationship between 28 species water beetles in 12 lentic samples and environmental factors of North Changbai Mountain was studied by Cononical Correspondence Analysis (CCA).The results showed that degree of underwater humus and altitude are the major factors correlated with beetles distribution,and the correlation coefficients of envirommental factors and axes of CCA were 0^8371 and 0^7206 respectively,while water temperature and plant density also had certain effects.Under the influence of environmental factors,the water beetles' populations were different in different habitat.Coelambus impressopunctatus,Colymbetes magnus,Helophorus browni,Haliplus spp.distributed in deep water pool.Water temperature was not important for those beetles.Ilybius sp.and Limnebius glabriventris correlated with altitude and humus. |
