| 摘 要： | 以粤北某矿横石河流域周围表层土壤2010年和2013年两批区域调查数据为基础,对其土壤中重金属含量变化趋势进行预测,并进行生态风险预警评估。结果显示,3年间土壤中Cd、Cu、Pb、Zn等元素含量降低明显,现累积速率分别为-0.001、2.88、3.71和3.11mg/(kg·a),相对累积速率以Cd最快,Zn、Cu、Pb次之;生态风险预警评估显示凉桥村和水楼下村的生态风险达到重警,上坝村为轻警。在无突变情景下,根据现累积速率预测了未来30年内的生态环境质量变化,并提出建议。 |

| Abstract: | Based on regional survey of Hengshi River Basin surface soil around asulfide mine in north Guangdong from 2010 to 2013, trend prediction of heavy metals in soil and the ecological risk warning assessment were studied. Results show that the content of Cd, Cu, Pb, and Zn in soil had reduced significantly during the three years, and the current accumulation rate of Cd, Cu, Pb, and Zn are 0.001, 2.88, 3.71 and 3.11 mg/(kg·a), respectively, and the relative cumulative rate decreases as the order of Cd, Zn, Cu, and Pb. The ecological risk warning assessment showsLiangqiao and Shuilou village under serious ecological riskand Shangba village under slight ecological risk. According to the current accumulation rate, changes of ecological environment quality over the next 30 years were predicted and suggestions were also given. |
