Abstract

Edera District is the one of separated districts of six districts in the Mappi Regency. The increasing of community population has caused an increase activities in resource utilization, especially in the Digoel River area. As a result of excessive utilization activities can potentially cause pollution that threatens the existence and continuity of organisms such as Gastropods. This study aims to determine the community structure of Gastropods in the Digoel River in Edera District, Mappi Regency. The study lasted for 3 months from January to March 2018 by using the survey method and reviewing several variables including: diversity index, uniformity index and dominance index. The results showed that at the 3 observation stations the total sample was 1233 individuals. The highest diversity index value was at station II, namely itlic. and lowest was at station I Ellobium chinense species. Uniformity index shows that the number of uniformity is not evenly distributed in all three stations due to the occurrence of certain types of dominance. Keywords: Gastropoda; Community Structure; Digoel River; Mappi Regeucy Regeucy

Edera区是马皮县六个区中独立的一个区。社区人口的增加导致资源利用活动的增加，特别是在迪戈尔河地区。由于过度利用活动可能造成潜在的污染，威胁到腹足类生物等生物的生存和连续性。本研究旨在确定马皮县Edera区的Digoel河中腹足类动物的群落结构。采用调查法，考察多样性指数、均匀度指数、优势度指数等变量，研究时间为2018年1 - 3月，为期3个月。结果表明，3个观测站共捕获1233只。多样性指数最高的是II站，即itlic。最低的是第1站的黄球藻种。均匀性指标表明，由于存在某些类型的优势，均匀性数量在三个站点中分布不均匀。关键词:腹足纲;群落结构;Digoel河;Mappi regey regey
