鲁中山地侧柏林区蜘蛛群落的研究

于1992～1994年对鲁中山地侧柏林蜘蛛群落进行了定时、定点和定量采集观测。对蜘蛛群落的种类、个体数量、多样性、优势度及稳定性等进行了分析。从季节变化看,蜘蛛群落组成的种类、个体数量、多样性8月份最高,1月最低。从垂直结构上看,灌草从蜘蛛亚群落各指标较高。另外还利用统计学的变异系数对蜘蛛群落的稳定性进行了讨论。

STUDY ON THE COMMUNITY OF SPIDER IN CHINESE ARBORVTTAE FOREST OF SHANDONG CENTRAL MOUNTAINS,CHINA

A survey on the spider community in Chinese arborvitae forest of Shandong Central mountains was counducted in years 1992 - 1994. 15 families and 68 species were found. The domanice,diversity and stability in different natural habitats of the spider community were compared. The species and number of spider of mountain foot is more than those in other habitats. All habitats shared similar characteristics in annual change. The species,number and diversity of the community in August is more than those in other seasons. In vertical distribution of Chinese arborvitae forest, the species,number diversity and domanice of spider community is highest in the patch of bush and grass.The coeffficient of variation was used in discussing the stability of spider community.
