Terrestrialisopodsthatactimportant roles for detritus decomposition are also sensitive to the changes in environmental conditions. Up to this time, it has been studied by this head investigator that the species composition of terrestrial isopods might reflect the degree of environmental naturality or human impact. However, quantitative study on isopods as a bio-indicator is a very few. In this study, the head investigator planned to make clear the relationship between species composition of terrestrial isopods and their habitat conditions especially concerning to the degree of human impact or environmental naturality. In 1996 and 1997, the head investigator surveyed in Kanto district ie Tokyo metropolitan area Chiba prefecture and Fukushima prefecture under various environmental connditions. Identified isopods in this study were mainly four species as following : Armadillidium fulgare, Nagarus maculatus, Porcellio scaber, Ligidium japonicum and sphaerillo obsculus. Many datum implied that theise species composition were characteristic to the degree of human impact or environmental naturality. The goal of this study was to analyze the relation between isopods speceis deistributuin and environmental naturalitu and to put the bio-indicator by terrestrial isopods. But, under many circumstances of school businesses, the goal of the study was not achieved completely. The head investigator will realize this subject another chanse cirtainly

对碎屑分解起重要作用的陆源等足类对环境条件的变化也很敏感。到目前为止，这位首席研究员已经研究过，陆生等足类动物的物种组成可能反映了环境自然或人类影响的程度。然而，以等足类动物作为生物指示剂的定量研究却很少。在这项研究中，首席研究员计划弄清楚陆生等足类动物的物种组成与其栖息地条件之间的关系，特别是与人类影响程度或环境自然性有关。在1996年和1997年，首席调查员在各种环境条件下对关东地区即东京都区千叶县和福岛县进行了调查。本研究鉴定出的等足类主要有四种：亮Armadillidium fulgare、斑点龙象Nagarus maculatus、粗糙瓷象Porcellio scaber、日本女贞Ligidium japonicum和钝球蛤Sphaerillo obsculus。许多资料表明，这些物种组成的特点，人类的影响或环境的自然程度。本研究的目的是分析等足类物种分布与环境自然的关系，并以陆生等足类为生物指示物。但是，在学校经营的许多情况下，本研究的目的并没有完全达到。首席调查员大约会在另一个机会认识到这个问题
