摘要

通过野外采样、室内测试及数理统计

对北碚区菜地规划区内前期不同土地利用方式下土壤的铅、镉进行研究。结果表明:(1)通过描述统计与方差分析得出不同土地利用方下铅和镉全量、有效态含量、生物有效性系数有不同程度的差异

土地利用方式对其有不同程度的影响。(2)在研究区内

车辆废气排放、肥料施用的差异是影响全量差异的可能因素

土壤pH值的差异、有效磷含量差异、铅与镉全量的差异是影响有效态含量差异的可能因素。全量的差异是影响生物有效性系数差异的主要因素。(3)以重庆市土壤铅、镉背景值为标准

通过地质累积指数法计算得出

菜地规划区内土壤铅、镉受轻度污染

其中混作地与水田土壤铅污染程度较菜地的明显

菜地土壤镉污染程度较水田和混作地的明显。

Abstract

through the field sampling

test in lab.and mathematical statistics

researched on the lead

cadmium of soil under different land-use types in before in vegetable field planning area of Beibei.The results showed that:(1)Through descriptive statistics and analysis of variance

under the different land-use types the total cadmium and lead

the contents of available lead and cadmium

the bioavailability index of cadmium and lead had different degree of difference.And the different land-use types had different degree...
