Abstract
土壤蜱螨目是土壤质量评价的较好指示生物,但还很少用于多环芳烃(PAHs)污染的研究。已有的研究主要采用群落组成参数作为指标特征,且大多在类群水平上,如,密度、类群多度、多样性指数和均匀性指数等。由于这些指标是建立在较粗的分类基础上,因此,评价结果通常变异性较大,不够稳定。本研究是在物种水平上,除对群落组成参数外,还着重对生活史和雌雄性比例等生物学特征进行了研究,以筛选更为敏感的指标特征。研究采用污染田与对照田对比的方法,于2008年对华东区一蔬菜田的PAHs污染及其对土壤螨群落结构的影响进行了调查研究。除土壤螨群落结构参数和16种优先监控PAH化合物外,还对土壤理化和重金属进行了测定。PAHs在污染田中的总浓度为18.7to26.8mgkg-1dwsoil,比对照田高5.3到7.6倍。污染田甲螨亚目低等类的密度和种丰富度比对照田分别高3.2到8.5和1.0到2.2倍。相反的,中气门亚目的1r策略选择种密度、雄性个体密度和雌/雄性比例在对照田比在污染田分别高0.9到1.1、2.2到3-3和1.0到2.6倍,且与总PAH浓度呈显著负相关。这一研究结果表明:甲螨亚目低等类和中气门亚目的1r种、雄性个体以及雌/雄性比例等相关特征对土壤PAH污染敏感,因而,可进一步筛选作为土壤污染的评价指标
