| 中文摘要 |
| 通过提取土壤中各结合态腐殖酸组分 ,研究华南地区不同土壤类型、不同结合态腐殖酸的三卤甲烷生成潜能 (THMFP) .结果表明 :①稳结态腐殖酸 (H2)的 THMFP最大 ,其次是松结态腐殖酸 (H1) ,紧结态腐殖酸 (H3)的 THMFP最小 ;②各土样不同结合态腐殖酸中 ,基本上是富里酸 (FA)的 THMFP大于胡敏酸 (HA)的 THMFP;③同属铁铝土纲的麻红壤、赤红壤和砖红壤 3者中 ,砖红壤各结合态腐殖酸的 CHCl3生成量最小 ;④水稻土和湿潮土两者各结合态腐殖酸的 CHCl3生成量的变化规律基本一致 . |
| 英文摘要 |
| Trihalomethane formation potential(THMFP) of various combined humus in different types of soils in South China was studied by extracting various combined humus in soils.The results show as follows:①THMFP of various combined humus has the order of the stably combined humus(H2)>the loosely combined humus(H1)>the tightly combined humus(H3);②THMFP of fulvic acid(FA) was generally higher than that of humic acid(HA) in all kinds of soils;③ The various combined humus of orthic latosol had less chloroform yields than orthic red earth and orthic lateritic red earth,though they all belong to the order of ferrallisols;④the chloroform yields of various combined humus of paddy soil and wet fluvoaquic soil had the same trend of changes on the whole. |
