On the premise of the land demand of the green petrochemical base in Zhoushan，aiming at the layout of reclamation for Da-XiaoYushan sea area with high sediment concentration and current velocity，based on the full understanding of natural environmental conditions，and combining with the research results of the current and sediment model，we analyze the different reclamation layout schemes for Zhoushan green petrochemical base. It is proposed that the shallow waters in the island flow shadow area should be fully utilized in conjunction with land use requirements，and the reclamation layout should comply with the main direction of tide current，and an ecological priority concept shall be adhered to. It may serve as a reference for reclamation projects in offshore island areas.
