摘要/Abstract

摘要： 研究了浙江哩铺铜矿废弃地土壤微生物生态特征和群落结构.结果表明,与对照土壤相比矿区土壤微生物生态特征发生了明显的改变,微生物呼吸速率减弱,微生物生物量显著降低,微生物生理生态参数C_mic/C_org下降、qCO₂值明显升高,重金属对土壤微生物生态特征有明显的影响.Biolog结果显示,矿区土壤微生物的群落结构发生变异,对能源碳的消耗量和速度明显升高,改变了微生物利用碳源的种类,使微生物消耗更多的能源,以维持其正常的生命活动,利用效率降低,明显不如对照土壤.由此可见,微生物生态特征是表征矿区复垦土壤重金属污染的灵敏、有效和可靠的生物学指标.

Abstract: Soil microbial features in Lipu copper mining and non-mine soil were studied comparatively. The results indicated that mine soil possessed obviously different microbial features such as lower microbial biomass carbon and soil basal respiration strength, C_mic/C_org decreasing, and higher microbial ecophysiological parameters qCO₂, indicating that heavy metal had a depressive impact on soil microbial eco-characteristics. Biolog data showed that mine soil microbial community structure was changed obviously, the speed and quantity of carbon consuming were increased significantly, and the kinds of carbon sources which soil microorganism used were changed, led to consume much more energies for maintaining the normal needs of its life. But the utilization efficiency was lower compared with the control. All the results showed that soil microbial eco-characteristics could be used as a sensitive, effective and liable index of mine soil environment qualities.
