摘要
通过对江西省鄱阳湖地区樟树-奉新、抚州-九江以及东乡-彭泽三条生态大剖面的表层土壤和农作物根系土的采集和土壤pH值、9个重金属元素全量和化学形态含量、13个营养有益元素有效态含量的分析测试,获得了极为丰富的数据,进而分析研究了土壤中重金属元素形态分布特征、全量与形态含量的相关性、形态随土壤pH变化规律,并提出了防治土壤酸化及其负效应的建议。
Basing on the sampling of surface soils and crop root soils along the three long-distence ecological sections at Zhangshu-Fengxin,Fuzhou-Jiujiang and Dongxiang-Pengze in the Poyang lake region of Jiangxi Province,and analysis measurement of pH values,total contents and species contents of 9heavy metal elements as well as effective species contents of 13 nutritive elements in soils,the abundant data were obtained to provide a future study on the distribution characteristics of chemical species and correlation between total contents and species contents of heavy metal elements in the soils,and regularily of variation of species with variation of pH in the soils,and to propose suggestions for the prevention and control of soil acidification and its negative effects.
