With the development of Ningbo and Zhoushan port , the development of port and channel becomes more frequent in recent years in Jintang waterway and the eastern side of the Chuanshan peninsula . The environmental factors of tidal currents and sediment are one of the basic elements in port construction . In order to understand and analyze the sea currents and sediment movement characteristics , the paper made a statistical analysis and discussed the characteristics of tides , currents and sediment movement of this area , on the basis of several hydrologic test data in recent years , and thus obtained the basic law of the tidal current movement in the region , temporal and spatial distribution characteristics of sediment movement and its migration law , which can provide a reference for the development of port and channel , marine environmental protection and other marine engineering constructions .%随着宁波和舟山港的发展，近年来金塘水道和穿山半岛东侧海域港口航道开发比较频繁。潮流泥沙环境要素是港口建设的基本要素之一，为了了解和分析该海区的水流、泥沙运动特性，根据近几年的多次水文测验资料，对该海区的潮汐、潮流、泥沙进行统计分析，探讨了潮汐、潮流和泥沙运动的特点，得出了本地区的潮流运动的基本规律，泥沙运动的时空分布特征及其运移规律。
