摘　　要：2008年5月,采用陷阱法在辽宁省清原县大苏河乡大湖生态站选取杂木林、红松林和落叶松林3种森林植被类型收集地表蜘蛛。共采集成熟蜘蛛标本1 825头,隶属于13科49种。调查发现:1)皿蛛科、漏斗蛛科及平腹蛛科是该地区的优势科,旋卷隙蛛Alloclubionoidescircinalis及皿蛛科一未定种为该地区的优势种;2)3种森林植被类型的地表蜘蛛群落组成存在明显的差异,杂木林中物种最丰富,分布有13科39种,红松林中分布有10科29种,而落叶松林中有8科28种;平腹蛛科在杂木林中最丰富,而在红松林、落叶松林中数量稀少;3)多样性指数存在一定差异,杂木林中个体数量最多,红松林中个体数量最少,Margalef指数及Menhinick指数最低值均出现在红松林,而最高值出现在落叶松林。In May 2008, the composition and distribution of ground-dwelling spiders were investigated using pitfall trapped method to assess the impact of forest type on spider diversity. Three forest types, i. e. , miscellaneous wood forest, broad-leaved Korean pine forest and deciduous Korean Pine forest were surveyed in Dahu Ecological Station in Dasuhe Town, Qingyuan County, Liaoning Province. A total of 1825 adult individuals were collected, belonging to 13 families and 49 species. The results showed： 1） Linyphiidae, Agelenidae and Gnaphosidae were dominant families, Alloclubionoides circinalis and one unidentified species of Linyphiidae were the dominant species; 2） the ground spider community composition were significantly different in the three forest types, 13 families and 39 species were collected from miscellaneous wood forest, 10 families and 29 species were collected from broad-leaved Korean pine forest and 8 families and 28 species were from deciduous Korean Pine forest; gnaphosid spiders were most abundant in miscellaneous wood forest, but sparse in the other two forest types; 3） the diversity indices were also different; the individuals in miscellaneous wood forest was significantly higher than the other two forest types, the Margalef index and Menhinick index were both lowest in the broad-leaved Korean pine forest, but highest in deciduous Korean Pine forest.
