崇明岛上沙地区蜘蛛种类及其动态分析

于2011年4月初到2013年10月底，在崇明岛上沙地区选择6个代表性区域，采用捕捉、扣管、扫网和陷阱法对蜘蛛种类进行系统调查和定点采集，共采集蜘蛛标本700头，初步鉴定出蜘蛛63种，隶属13科38属，另有8种鉴定到属。该地区蜘蛛优势种类是跳蛛科、肖蛸科、园蛛科、狼蛛科。文章介绍了蜘蛛种群年度消长规律，同时探讨了不同环境因子的变化对蜘蛛种群的影响，分析表明：蜘蛛种群密度与生境和农药的使用存在显著差异，蜘蛛适宜生存的温度在15℃～35℃，适易的相对湿度在65％-85％。

Analysis on the species and dynamics of spider communities in Shangsha Area of Chongming Island

The research was carried out during April 2011 and October 2013 by intensive investigations and collection in shangsha representative area of Chongming Island. 700 spider individuals were collected, Some of the specimens were identified by the expert, which belong to 13 families, 38 genera and 63 species.
