江西特色矿区蜘蛛资源分布及多样性比较研究
首发时间:2014-11-07
摘要:江西为环西太平洋成矿带的组成部分,矿产资源丰富,是我国主要的有色、稀有、稀土矿产基地。本调查涉及的江西矿产矿藏区域包括抚州相山铀矿、贵溪冷水坑银矿、临川茅排金矿、赣州稀土矿、德兴铜矿和丰城煤矿。经鉴定,江西特色矿区有蜘蛛39科191属563种,其中,有5个江西新记录科、39个江西新记录种和155个未确定种。其蜘蛛类型以农林和人居区常见种类为主,不同矿区具少数特有蜘蛛种类。群落结构分析表明,蜘蛛科数依次为D>E>A=C>B>F;蜘蛛属数依次为D=E>C>A=B>F;蜘蛛种数依次为E>C>B>D>F>A;蜘蛛个体数依次为E>D>B>C>F>A。多样性分析表明,Marglef丰富度指数M依次为A>F>C>B>D>E;Shannon-Wiener优势度指数D依次为E>C>B>D>F>A;Smipson多样性指数H′依次为C>E>A>D>F>B;Pielou均匀度指数J′为A>C>F>D>E>B。聚类分析表明,各矿区蜘蛛群落间相似性大小依次为A、C、F、B、E和D,交流程度逐渐降低。江西特色矿区蜘蛛多样性的形成主要与矿区内地形地貌复杂、矿产矿藏区域物化环境变化较大、植被多灌丛草甸类型、穴居空间较多和人为干扰频繁等因素密切相关。

A Comparative Study on the Spider Resources,Fauna and Diversity in Unique Mineral Areas in Jiangxi
Abstract:.Jiangxi province, part of west Pacific metallogenic belt, was not only rich in mineral resources, but also China's major non-ferrous, rare, and rare earth mineral base. Unique mineral areas in the study include the Xiangshan uranium mine, the Lengshuikeng silver mine, the Maopai gold mine, the Ganzhou rare earth mine, the Dexing copper mine and the Fengcheng coal mine. After identification, it had been found that there were 563 known species belonging to 39 families and 191 genera, of which, 5 new records families in Jiangxi, 39 new record species in Jiangxi and 155 undefined species. There were many spider types in unique mineral areas in Jiangxi, in which common species for agroforestry and residential district predominate, with few endemic species in different mineral areas. Analysis of community structure showed that the spider family number, followed by D>E>A=C>B>F; the size order of spider genera number were D=E>C>A=B>F; spider species number were E>C>B>D>F>A; spider individual number were E>D>B>C>F>A. Diversity analysis showed that, the size order of Marglef richness index M were A>F>C>B>D>E; Shannon-Wiener dominance index D were E>C>B>D>F>A; Smipson diversity index H' were C>E>A>D>F>B; Pielou evenness index J' were A>C>F>D>E>B. The cluster analysis showed that the spider community similarity between different mineral areas, followed by A, C, F, B, E and D, their exchange decreases gradually. The formation of spider diversity in unique mineral areas in Jiangxi were closely related to complex topography, great changes for physical and chemical environment, vegetation types with more meadow burrowing, more cave space, frequent human disturbances and other factors in these mineral areas.
