摘要: 为了探讨重金属污染过的土壤经修复后其土壤生态的变化情况,于2014.12—2015.12期间,采用干漏斗法针对经过不同修复处理后的土壤动物群落结构进行追踪研究。研究结果表明:由于污染抑制了某些土壤动物的生存,导致土壤动物的个体数与类群数锐减;而杜绝污染水源后,修复植物根系土壤动物群类群数与个体数增加,并且蜱螨目、弹尾目和线虫纲等常见的土壤动物类群修复效果明显。说明被重金属污染过的土壤在断绝污染水源后,人工种植修复植物不仅可以改善土壤物理性质,而且对根系土壤动物也有修复作用。

Abstract: The objective is to explore the ecology changes of repaired soil which is polluted by heavy metals. Follow-up studies on the structure of fauna communities in soil after different remediation treatments were conducted with Tullgren method during December 2014 to December 2015. The results showed that certain soil animals were inhibited for survival because of the contamination, which resulted in a sharp decline of individual number and class group number. When contaminated water source was eliminated, the number of individual and class group of soil animals increased after plant roots’repairing, and the remediation effects on normal soil fauna communities such as Acarina, Thysanura, Nematoda were obvious. It indicated that when the contaminated water source was eliminated, in soil contaminated by heavy metals, the artificial cultivated repairing plants not only improved the soil physical properties, but also repaired the soil fauna.
