摘要:

早在1957年前人就对武汉东湖介形虫的属种进行了调查,当时共记载了6属8种及1新种。如今时隔60年后,武汉东湖的深度、面积和水质状况等发生了巨大变化,这些变化可能会造成水生生物群落的改变。本文于2014年再次调查了武汉东湖现代介形虫的物种分布情况,共发现介形虫8属15种,其中仅有2种介形虫与1957年的报道相同,介形虫的物种和生物群落组成都发生了很大变化。综合1957年和2014年武汉东湖的生态条件和水环境数据,本文认为介形虫群落组成的变化灵敏地反映了上世纪50年代以来武汉城市化和工业化等人类活动引起的湖泊环境变化过程。

Ostracod species had been identified and described by previous studies in the Lake Donghu, Wuhan in 1957. However, the environment and water conditions of Lake Donghu have been changed dramatically in the past 60 years, which may cause the succession in ostracod assemblage. In this paper, the species distribution of modern ostracod in Lake Donghu was investigated again in 2014. There were 15 species of 8 genera of ostracods, of which only two species were the same as those reported in 1957, and the ostracod species and community composition have undergone great changes. We summarized the ecological conditions and water environment data of Lake Donghu in 1957 and 2014, and suggested that the changes of the ostracod community assemblages sensitively reflected the processes of human-induced deterioration of water quality in Lake Donghu.
