| 摘 要： | 测定了湖州市表层土壤的重金属含量，对各元素的累积趋势进行了预测，利用克里格插值法揭示了该地区土重金属环境容量的空间分布特征。结果表明各元素的累积增长率大小顺序为：Cd〉Pb〉zn〉Cu〉Ni〉Cr〉Hg〉As。不同元素的环境容量差别巨大，且消耗容量的速度也有很大差异，消耗最快的元素是Pb，最慢的元素是Hg。90％以上面...

| Abstract: | The contents of heavy metals were determined to predict the trend of pollution by heavy metals in surface soils of Huzhou.The Kriging method was applied to disclosing the spatial distribution of environmental capacities for heavy metals in surface soils.The results showed that the accumulation increasing ratios of different heavy metals followed the order of Cd>Pb>Zn>Cu>Ni>Cr>Hg>As.Environmental capacity and its consuming velocity of different elements were of diversity.The environmental capacity of Pb was ... |
