摘 要: 对赣东北区域的鹰潭龙虎山景区(A)、弋阳龟峰景区(B)、上饶集中营景区(C)、玉山县城南郊(D)和玉山三清山景区(E)蜘蛛资源及区系分布进行调查,共采得蜘蛛标本708份。经分类鉴定得知:它们分别隶属18科54属95种,其中江西新记录种有6种,未确定种有9种。蜘蛛多样性的研究表明:丰富度指数M大小依次为:D>C>E>B>A;优势度指数H′大小依次为:E>A>C>B>D;多样性指数D大小依次为:B>A>C>D>E;均匀度指数J大小依次为:D>B>C>A>E. 蜘蛛群落间的聚类分析表明:弋阳龟峰景区(B)和鹰潭龙虎山景区(A)蜘蛛群落相似性最大,群落间更连续,蜘蛛种类交流频繁,其他蜘蛛群落关系连续性程度依次为上饶集中营景区(C)、玉山县城南郊(D)和玉山三清山景区(E),蜘蛛种类交流程度也依次减少。

Abstract: The survy on spider resources and fauna of Longhushan scenic area in Yingtan city(A), Guifeng scenic area in Yiyang county(B), Shangrao camp scenic spot(C), the southern suburbs of Yushan county(D) and Sanqingshan scenic area in Yushan county(E), which are located at northeastern in Jiangxi province, obtain 708 copies of spider specimens. By the classification and identification firstly, they are attached to 18 families, 54 generas and 95 species, of which 6 species are new recorded in Jiangxi province and 9 species are undetermined. Spider diversity studies have shown that the size of the richness index M order is D>C>E>B>A, dominance index H′ order is E>A>C>B>D, diversity index D order is B>A>C>D>E, the size of the evenness index J as follows: D>B>C>A>E. Finally, spider communities between the cluster analysis show that the spider community between Longhushan scenic area in Yingtan city (A) and Guifeng scenic area in Yiyang county (B) is the more similar and continuous, with frequent exchanges of spider species, then the continuity degree between the other spider communities is followed by Shangrao camp scenic spot (C), the southern suburbs of Yushan county (D) and Sanqingshan scenic area in Yushan county (E), the degree of spider species in exchange successive reduce.
