中文摘要：
采用室内培养的方法,比较研究了绿化植物废弃物和草炭添加量对自制Cu污染土壤中Cu形态随时间的变化。结果显示：随着供试改良材料添加量的增加,土壤具有碳酸盐结合态Cu逐渐降低、铁锰氧化物结合态Cu呈先增加后减少和有机结合态Cu逐渐增加的趋势;供试改良材料添加量高于60%时,草炭处理较绿化植物废弃物处理有机结合态Cu所占比例高、碳酸盐结合态Cu和铁锰氧化物结合态Cu所占比例低;随着培养时间的增加,供试改良材料逐渐降解,有机结合态Cu呈现略微降低趋势。
英文摘要：
In indoor culture the Cu form changes of Cu-contaminated soils with time were comparatively studied by adding both greening plant waste and peat.The results showed that with the amount of ameliorating materials increasing,the concentration of carbonate-bound Cu decreased gradually,and however,the Fe-Mn ox-ides-bound Cu increased firstly and then decreased and the Cu of organic form had an increasing trend.When the added amount of ameliorating materials was over 60%,the Cu of organic form under the peat treatment had a higher percentage than that under the greening plant waste treatment,but the percentages of both carbonate-bound Cu and Fe-Mn oxides-bound Cu were less;And with the culturing time increasing,the added ameliorating materials were degraded gradually,and the Cu of organic form also presented a slightly decreasing trend.
