Changes in the morphology of the coastal zone were monitored during the period from 1996 to 2000. A Golden Software system was used to calculate the differential surfaces between the surveys in order to investigate the local patterns of accretion and erosion and to determine the volume changes between consecutive surveys. Volumetric studies showed that the net accretion in the study period was about 1.7×10 8 m 3. Between July 1996 and October 1996, a time interval characterized by intense runoff, an accumulation of about 4×10 8 m 3 occurred. In the period from October 1996 to October 1998, a period of diminution in runoff and sediment supply in the upstream, an erosion of 8.9×10 7 m 3 occurred, indicating sediment starvation of the area. Between October 1998 and October 2000, due to an inadequate supply of runoff and sediment, about 1.4×10 8 m 3 of sediments was eroded and transported offshore.展开更多

As a new economic growth pole, Circum-Bohai-Sea Region should focus on internal financial deepening. In this paper, SWOT analysis is used to observe the level of financial deepening in Circum-Bohai-Sea Region, and some related policy suggestions are given in the end.展开更多
