In this study, the microbial activity and functional diversity of microbial communities in eroded soils from an abandoned Pb, Zn, Ag mine were evaluated. The results showed both total and soluble metal loadings in these soils increased with proximity to the mine reserve. Indictors of soil microbial features varied significantly because of soil and water loss stress. Soil microbial biomass and viable population size (plant counts) were negatively affected by erosion levels, but the size of soil basal respiration...

In this study, the microbial activity and functional diversity of microbial communities in eroded soils from an abandoned Pb, Zn, Ag mine were evaluated. The results showed both total and soluble metal loadings in these soils increased with proximity to the mine reserve. Indictors of soil microbial features varied significantly because of soil and water loss stress. Soil microbial biomass and viable population size (plant counts) were negatively affected by erosion levels, but the size of soil basal respiration rate and microbial metabolic quotients were positively influenced by the enhanced erosion strength. Microbial community structure also changed with increasing erosion, as indicated by Biolog data and principal component analysis of Biolog community metabolic profiles. Soil microbial metabolic profiles (AWCD) values, community richness and diversity index in minesoils decreased remarkably as compared with adjacent uneroded mine soils (P<0.001). It was suggested that the decline of soil microbial community functional diversities would occur in the soils affected by loss of water and soils from mine areas, decreased microbial number used energy carbon and utilization ability of microbial communities for carbon substrates. So the microbial activities and community functional diversities can effectively indicate soil environmental quality transition from mine eroded area to uneroded conditions.

通过对浙江省天台铅锌银矿区侵蚀土壤的微生物活性以及微生物群落功能多样性研究,结果表明:人为开矿使矿区土壤环境呈现不同层次的加速侵蚀特征。矿区侵蚀土壤的几种重金属含量比无明显侵蚀土壤有明显的增加,且其基本理化性质相应变差。矿区侵蚀土壤微生物特征发生了显著的变化,与无明显侵蚀土壤相比,微生物生物量和可培养细菌数量显著降低,但土壤基础呼吸和微生物代谢商(qCO2)值却明显升高。Biolog测试结果显示,随着土壤侵蚀程度的加剧,其微生物群落结构亦发生了相应改变,侵蚀土壤微生物群落的丰富度、多样性指数、均匀度均显著低于对照土壤,且几项指标都达极显著水平差异(P<0.001),表明矿区水土流失引起了土壤微生物群落功能多样性的下降,减少了能利用有关碳源底物的微生物数量,降低了微生物对单一碳源底物的利用能力,最终导致土壤微生物群落结构和功能多样性发生变化。

The soil daily basal respiration potential ranged from 36.23 to 58.52 mg·kg -1 ·d -1 , and the potentials in the root layer of 40 or 90 yr old were greater than that of 10 yr old tea bushes.The daily qCO 2, ranging from 0.30 to 0.68, was in the reverse trend....

Soil basal respiration potential, metabolic quotient (qCO 2), and activities of urease, invertase and acid phosphomonoesterase were investigated in the root layer of 10 , 40 , and 90 yr old tea bushes grown on the same type of red soil. The soil daily basal respiration potential ranged from 36.23 to 58.52 mg·kg -1 ·d -1 , and the potentials in the root layer of 40 or 90 yr old were greater than that of 10 yr old tea bushes.The daily qCO 2, ranging from 0.30 to 0.68, was in the reverse trend. The activities of test three enzymes changed differently with tea bushes' age. Urease activity in the root layer of all age tea bushes ranged from 41.48 to 47.72 mg·kg -1 ·h -1 and slightly decreased with tea bushes' age. Invertase activity was 189.29~363.40 mg·kg -1 ·h -1 and decreased with tea bushes' age, but its activity in the root layer of 10 year old tea bushes was significantly greater than that in the root layer soil of 40 or 90 year old tea bushes. Acid phosphomonoesterase activity (444.22~828.32 mg·kg -1 ·h -1 ) increased significantly with tea bushes' age. Soil basal respiration potential, qCO 2 and activities of 3 soil enzymes were closely related to soil pH, soil organic carbon, total nitrogen and C/N ratio, total soluble phenol, and microbial biomass carbon, respectively.

Studies on the soil microbes,soil enzyme activity and soil biochemical intensity in copper mining wasteland indicated that the total quantity of major soil microbes declined by 68.43%~80.32% ,compared with that of the non-minig soil. The proportion of bacteria and actinomyces decreased, while that of fungi did not changed obviously. The amount of major physiological groups including ammonifiers, nitrogen fixing bacteria, cellulose decomposing bacteria, aerobic nitrogen fixing bacteria and anaerobic nitrogen fixing bacteria all decreased, and soil basic respiration descended, compared with the control. The activity of soil enzymes weakened ,which included urease, sucrase, proteinase, acid phosphtase, peroxidase, polyphenol oxidase and dehydrogenase. Soil biochemical intensity including ammonification, nitrification, nitrogen fixation and cellulose decomposition descended, and the circulation of C and N in mining soil inhibited. All the results showed that the weakening of microbial activity was one of major characteristics in reclaimed mining soil.
