摘要
对新疆莎车县棉田及相邻荒漠过渡带蜘蛛种类,群落结构及动态进行了初步的研究和分析。棉田及相邻荒漠过渡带的蜘蛛有13科3、6属、39种。蜘蛛在两个不同生境群落特征及多样性有明显的差异性。逍遥蛛科和蟹蛛科为两个生境中共同的优势科。荒漠过渡带蜘蛛群落的物种数、个体数量、多样性、均匀度、稳定性都高于棉田蜘蛛群落的对应特征。荒漠过渡带蜘蛛群落结构的变动对棉田内蜘蛛群落的变化有明显的影响,可以初步肯定荒漠过渡带的种库作用。
From May to Auguest in 2006 a primary study on cemmumity structure and dynamics of spider in transitional zone between cotton field and its adjacent desert in Shache county, Kashi district, Xinjiang was made. 39 species belonging to 36 generas and 13 families are found in transitional zone and cotton field. There were significant differences in character and diversity of spider community in the two habitats. Philodromidae and Thomisidae are dominant families. The species, number, diversity, evenness and stability of community of spider in transition zone are all higher than these in cotton field which is adjacent to the desert. The changes of spider community structure in transitional zone has important effect on the changes in cotton field. Transitional zone which is adjacent to cotton field is the species pool of cotton fields.
