T he research including organic carbon ,sulfide ,petroleum ,heavy metal of the sediment of the sea area around Qushan Island is present .Compared the land -sea distribution and hydrological dy‐namic background ,the paper show some conclusionding ,as follows :(1) all quality factors of the sedi‐ment is not bad to one class the sediment of the national standard ,but inorganic nitrogen ;(2) the site No .1 ,3 higher sulfide is originated from Qushan Island ;(3) petroleum had little difference between sits ,but No .06 ,which is from the oil leakage of sail berthing wharf ;(4)organic carbon and heavy met‐al of the sediment is general resemblance ,the higher ratio of Cu ,Pb uniform with background vaule of the sea area of Zhoushan Ids .%2014年9月于浙江衢山岛海域采集了10个站位的沉积物样品，对有机碳、硫化物、石油类和重金属等理化参数进行了检测分析。结合陆海分布、水文动力背景，得到以下结论：（1）研究区沉积物质量符合国家第一类沉积物质量标准；（2）硫化物较高的站位，其污染物主要来源为衢山岛；（3）石油类除S6站位外，其他各站位间差别不大，其可能是码头船只柴油渗漏所致；（4）有机碳和各重金属的站位变化不大，Cu、Pb的相对值较高，其与海区整体背景值一致。
