摘  要：
采用GPS定位和土钻取样相结合的方法,研究了河南境内淮河干流及其四条支流(贾鲁河、惠济河、双洎河、清巽河)沿岸2 km范围内土壤重金属铅、镉含量及其空间分布规律。结果表明:淮河干流及其四条支流铅含量均未超过国家三级含量标准,大体处于二级含量标准与三级含量标准之间,淮河干流与四条支流之间铅含量无明显差别。而镉的污染程度比较严重,其中惠济河、贾鲁河支流污染最重,在0～20 cm、20～40 cm、40～80 cm土层中土壤镉含量超三级含量标准率均在50%以上,双洎河支流、清巽河支流和淮河干流污染相对较轻。

摘  要：
By means of GPS and soil core sampling,this paper studied the content and distribution of soil heavy metals lead and cadmium in 2 km scope along the Huaihe River and its four branches(Jialu River,Huiji River,Shuangji River and Qingxun River) in Henan province.The results indicated that the lead content in soil samples along the Huaihe River and its four branches did not surpass the national third level standard,being roughly between the national second level standard and third level standard.Soil lead content was not different between the Huaihe River and its branches.However,the pollution degree of cadmium was quite serious,the pollution of cadmium along the Huiji River branch and Jialu River branch was heavier.The rate of soil samples in which the cadmium content in 0～20,20～40 and 40～80 cm soil layers surpassed the national third level standard was above 50%.The pollution of cadmium along the Shuangji River branch,Qingxun River branch and Huaihe River was relatively lighter.
