Abstract :
Based on underwater terrain datum of Shanghai petrochemical Co. LTD´s frontier area, the corresponding digital elevation model was built by GIS to analyze the law of erosion/accretion in Jinshan deep groove and the frontier area nearby systematically. The results show that: The erosion exceeds accretion in Jinshan deep groove near frontier area from 2000 to 2008. 2002 is turning. Accretion plays an important role from 2000 to 2002; on the contrary, erosion exceeds accretion from 2002 to 2008. Jinshan deep groove erodes towards shore and below. The rate of Jinshan deep groove´s north offshore distance is growing in Shanghai petrochemical Co. LTD´s frontier area; reasons of change from accretion to erosion in Jinshan deep groove includs not only the natural factors but also the influence of projects near the shore.
