Morphological and environmental's factor's characteristics of ciliated protozoa, the genus <I>Vorticelia</I>and<I>Pseudovoticella</I>in entrophicated Lake Kasumigaura were studied. <I>V.campanula</I> and <I>V.convallaria</I> were often appeared in the lake through the yera. V. picta increased from winter to spring season, while <I>V.vestita</I> was often observed from spring to early summer. In the study of environmental factors, it was found that<I>V. campanula</I>and V.convallaria could inhibit at a high alkaline pH value 9.47, further <I>V.vestita</I> could do at allcaine pH value 8.74. From the result of the appearance of ciliates, the pollution level in Lake Kasumigaura was corresponded to α-mesosaprobic zone during summer, while inwinter β-mesosaprobic zone.
