摘　　要：根据对中国稻田狼蛛亚群落结构及多样性的分析,结果表明:全国稻田狼蛛共计有7属30种,中国稻田狼蛛亚群落的主要成分是水狼蛛属(Pirata)和豹蛛属(Pardosa),大多数地区共享的优势种群是拟水狼蛛(P.sub peraticus)和拟环豹蛛(P.pseudoannulata).但稻田狼蛛亚群落的结构和多样性特征因各稻作区的地理、气候等环境因子以及亚群落本身的组成成分的不同而异,经系统分析,可将全国各稻作亚区狼蛛亚群落组成特征划分为4大类型:(1)内陆温带型;(2)沿海亚热带型;(3)东北平原型;(4)高原温带型.稻田狼蛛亚群落结构的稳定性和多样性呈现由东南向西北、由低纬度向高纬度依次递减的规律.The structure and diversity of the wolf spider subcommunity in paddy fields in China are reported. In terms of analysis, there are in total 30 species of wolf spiders, belonging to 7 genera of Lycosidae family, found in paddy fields of China. Among them, the main components are Pirata and Pardosa, and the dominant species are Pirata subpiraticus and Pardosa pseudoannulata. The characters of the structure and diversity of the wolf spider subcommunity are changeable as a result of the differences of environment factors and components of the subcommunity itself, and may be divided into 4 types. In the amount of species and the stability of the structure of the subcommunity, there is a decreasing trend both from southeast to northwest and from lower latitude to higher latitude.
