A　series　of　pollutant　content　tests　of　organic　matter,　total　nitrogen,　total　phosphorus　and　heavy　metals　were　performed　on　the　river　sediment　and　overlying　water　obtained　from　five　sites　in　Jin＇an　District,　Fuzhou.　Partition　coefficient　was　introduced　to　study　the　correlation　of　pollutants　between　the　river　sediment　and　overlying　water.　The　correlation　of　pollutans　between　sediment　and　overlying　water　was　analyzed　by　the　distribution　coefficients　of　organic　matter,　total　nitrogen,　total　phosphorus　and　heavy　metals.　Then,　introduced　the　relationship　between　the　standard　deviation　of　partition　coefficient　and　correlation　coefficient,　discussed　the　correlation　between　pollutants　in　sediment　and　overlying　water,　and　clarified　its　key　influencing　factors.　The　results　show　that　the　partition　proportion　of　different　pollutants　in　sediment　and　overlying　water　is　different,　and　the　correlation　coefficient　between　pollutants　in　overlying　water　and　sediment　is　quite　different.　The　more　stable　the　pollutant　distribution　coefficient　is,　the　higher　the　correlation　is　with　the　pollutants　in　the　overlying　water.　The　clay　content,　organic　matter　content　and　plasticity　index　of　sediment　have　a　significant　impact　on　the　pollutant　partition　coefficient.　The　pollutant　partition　coefficient　increases　with　the　increase　of　clay　content　in　the　sediment,　and　the　heavy　metal　partition　coefficient　increases　with　the　increase　of　organic　matter　content　in　the　sediment.　The　partition　coefficient　of　organic　matter　and　total　nitrogen　show　an　increasing　trend　with　the　increase　of　plasticity　index.　There　is　a　good　linear　relationship　between　the　logarithm　of　heavy　metal　partition　coefficient　and　the　plasticity　index　of　sediment.　©　2023　China　National　Publications　Import　and　Export　(Group)　Corporation.　All　rights　reserved.
