Community structure of soil mites in Shanghai urban greenbelts and its significance as bio-indicator in assessing urban greenbelt soil quality;
结果表明:城市绿化带土壤蜱螨目群落结构特征在很大程度上有别于自然土壤和农业土壤,反映了城市绿化带为一新型生态系统;城市绿化带土壤质量较差,但土壤蜱螨目仍然保持了较高的种类丰富度和密度,是恶劣环境评价的较好指示生物类群;除蜱螨目密度和种类丰富度外,甲螨亚目的无翼类、低等类和中气门亚目的种类丰富度和密度以及中气门亚目雌雄性比对环境变化敏感,且这些指标特征对不同环境土壤质量的评价结果基本一致,是较好的生物指标。
