摘要
通过对营口市旗口镇老解放河流域污灌区农田土壤的调查与研究表明,老解放河流域部分农田土壤存在低风险,由于老解放河中下游是提水点,所以中下游农田土壤污染程度高于上游和下游,且下游高于上游。生态危害最大的污染因子为铬。
According to survey and research of farmland soil of old XieFangHe basin in QiKou town of YingKou city,part of the farmland soil has low ecological risk.Because water points located in middle and downstream,so farmland soil pollution level in middle and downstream is higher than that in upstream and downstream.And the pollution level in downstream is higher than that in upstream.The greatest pollution factor of ecological harm is Cr.
