摘要
研究了沙坡头地区蜘蛛群落在不同固沙方式下的变化,结果表明,在采样范围较为局限的情况下,蜘蛛群落由7科、7属组成;逍遥蛛科(逍遥蛛属)、平腹蛛科(平腹蛛属)为研究区蜘蛛群落的优势科(属);人工无灌溉固沙方式下,蜘蛛群落的个体数、物种丰富度和物种多样性随固沙时间的延长而增加,但不与天然固沙和人工灌溉固沙方式下的以上各指数趋同.
The features of araneid community under the conditions of artificial plants in Shapotou region were studied.The results show that the araneid community is composed by 7 genera and 7 families.The dominant families or genera are Philodromidae and Gnaphosidae.As the time of sand dune control elongating,the indices,such as the number of individual,the richness of genera and the biodiversity of genera are increased.But the tendency of their change is different from that under the natural and irrigation conditions.
