摘　　要：以宁波海域甬江口倾倒区为例,将倾倒区分成12个分区,根据疏浚物倾倒期间对该倾倒区连续4个月每月一次(2013年3月、4月、5月、6月)的水下地形测量结果,分析倾倒区各分区的水下地形冲淤情况,并结合倾倒区各区域本身的地形,来探讨倾倒区分区倾倒的可行性,为往后开展倾倒区分区倾倒管理提供一种新的思路。This article made Yongjiang estuary dumping area as an example to discuss about subarea dumping. The dumping area was divided into 12 subareas,and its topography was measured once a month in 4 sequencing months （March, April, May and June respectively, in 2013） during the period of dredged materials dumping. After analyzing the scouring or silting status and topography of the subarea, we discussed about the feasibility of subarea dumping. This research offered a new idea for subarea dumt）ing manazement.
