| 摘 要： | 为了研究红寺堡扬黄灌溉工程实施后给该地区农业环境带来的影响，以红寺堡的主要作物——小麦和玉米为研究对象，对作物和土壤中重金属元素Pb，Cr，As，Cd，Cu，Zn和Hg质量含量进行了调查分析和评价．结果表明，作物中各污染物单项污染指数均小于1，作物未受到污染；土壤综合污染指数小于0．7，属清洁土壤．说明目前红寺堡灌区农业环境质量良好．

| Abstract: | To understand the effect of Hongsipu irrigation project on agriculture environment quality in this region, heavy metals contents in crop, wheat and corn, and soil were determined. Pollution index were calculated. The results showed that single pollution index for all analyzed elements were less than 1 no matter what was crop or soil, which means crop and soil were not polluted. As pollution index of soil was less than 0.7, so soil is clear. |

| Keywords: | heavy metal elements environmental quality pollution index |
