摘要： 以温州灵昆岛围垦区土壤为研究对象，进行了Cd、Cr、Cu、Zn、Mn、Ni、Pb、Hg和As的测定及风险评价，为合理规划围垦区土壤提供理论依据. 结果表明，灵昆岛围垦区土壤均受Cd和Hg污染最为严重，其地累积指数高于其他重金属元素，且对土壤重金属的潜在生态风险贡献最大. 在围垦区内，底泥吹填区土壤中重金属含量最高，其次为农业生产用地. 底泥吹填区土壤浸出液具有中等毒性，使热带爪蟾胚胎无法存活，建议在吹填区土壤开发利用之前采取一定的修复.

Abstract: The reclamation district of Lingkun Island in Wenzhou was taken as a study object in order to supply reference for rational planning of reclamation district, through determinations and risk assessments of heavy metal Cd、Cr、Cu、Zn、Mn、Ni、Pb、Hg and As in samples collected from six areas. The results showed the soils of reclamation district area were polluted by Cd and Hg，with the geoaccumulation index of Cd and Hg higher than that of other heavy metals, which contributed to the ecological risk of heavy metals in reclamation district. The contents of heavy metals in the soil of survey area were sediment reclamation district> agricultural district> other 4 districts. The Luminescent bacteria tests indicated the soils of sediment reclamation district belonged to medium toxicity, where the Xenopus tropicalis embryos hardly survived. Therefore, recovery methods of sediment reclamation district should be taken before the utilization and development.

Key words: Lingkun Island, reclamation district, heavy metals, ecological risk
