苔藓土壤动物种群动态的初步研究

A Preliminary Study on The Population Dynamics of Moss Soil Fauna

摘要: 本文是１９９２～１９９３年对上海市区苔藓土壤动物调查和研究的结果。重点对苔藓土壤动物优势种属及常见类群的季节动态进行了描述，并初步分析了各种生态因子对苔鲜土壤动物种群季节动态影响。结果表明，土壤温度、湿度和苔藓植物的生长状况对土壤动物种群季节动态有明显影响，优势种跗线螨和常见种覆盖头甲螨，作为苔藓土壤动物的代表种，对高温、干旱、低温等不利环境因素，表现出极强的忍耐力和快速繁殖能力。

Abstract: The present paper is based on the investigations and studies about moss soil fauna in Shanghai.The paper describes the population dynamics of the dominant genera and the common-seen genera of the moss soil fauna community and preliminarily analyses the effect of biotic and abiotic factors on moss soil fauna community structure and population dynamics.
