摘要
采用潜在生态危害指数法和GIS空间分析技术,对舟山市钓梁高涂养殖区沉积物中的Cu、Pb、Zn、Cd进行了综合定量化污染评价研究。研究结果表明:整个调查区域都属于轻微生态危害,且都是靠近排污口以及淤泥积压、物质交换周期长的渔港附近区域生态危害程度较重。
The comprehensive quantitative pollution assessments were carried out by the geographic infor- mation system （GIS） and potential risk index methods on copper, lead, zinc and cadmium in sediment in Diao- liang aquafarm area of Zhoushan. The results showed that all of the survey area belonged to the light ecological risk and the ecological risk level of the region was heavier near the sewage out fall, silt backlog and fishing port which has more long material exchange cycle.
