| 摘 要： | 以沈阳沈抚灌区上游指定区域为研究对象,对停灌10多年来土壤中重金属镉和铬以及有机物石油烃进行了单因子指数法评价,同时运用Arcgis软件分析制定出了采样区域单项污染指数分布图,按照单项污染指数评价,结果表明:重金属总镉和总铬以清洁级为主,有机物石油烃以重污染为主。Arcgis插值分析得出空间分布图表明:重金属总镉含量不受灌渠分布影响。重金属总铬北部区域大于南部区域。灌渠对有机物石油烃含量影响明显,对于停灌10多年有机物石油烃修复效果,旱田作业要好于水田作业。

Actuality Evaluation of the Soil Quality in the Upstream of Shen-Fu Irrigation Area Based on GIS |
| |
| Abstract: | The upstream of the Shen-Fu irrigation area was investigated.The residues of heavy metals(Cd,Cr)and petroleum hydrocarbon in soil without 10-years irrigation were evaluated with single pollution index,and the distribution map of single pollution index in sampling area was worked out by Arcgis software.The results of single pollution index evaluation showed that the heavy metal(total Cd and total Cr)contents were mainly at clean level and the petroleum hydrocarbon content was mainly at heavy pollution level.The spatial distribution map of Arcgis interpolation analysis indicated that the irrigation channel distribution had no effect on the total Cd content,the total content of Cd in northern area was more than that in the southern region,irrigation channel had an obvious influence on organic petroleum hydrocarbon content,the remediation effect without 10-years irrigation of petroleum hydrocarbon contamination by dry field operation was better than that by paddy field operation. |
