%X Using remote sensing data from Dec.1976 to Jan.2003 and spatial analysis of GIS,this paper analyses the dynamic change of the newborn estuary wetland since channel diversion of the Yellow River to Qingshuigou.The research area is a sector area,composing of three evident objects:a Yellow River inflexion near Kenli County government,northwest inflexion of Guhe reservoir and northeast inflexion of Guangbei reservoir.By the visual interpretation of remote sensing images at different phases,we can get the borderline between land and ocean.Comparing the borderlines of the research area supported by GIS,the areas of siltation and erosion can be identified and their scope can be computed.The results indicate that the increase and decrease of newborn estuary wetland are ongoing alternately because of the Yellow River siltation and the ocean erosion,and the area of net increase is declining gradually.Within 26 years,the newborn estuary wetland got a net increase of 17 154.41ha,and the annual average net increase is 657.76ha.The wetland area was a net increase before 1993,while this net increasing trend declined gradually after 1993.At the same time,the alternative periods of increase and decrease of the newborn wetland become shorter and shorter from 2.52 years to 1.06 years.Before 1993,the increased parts are located in the new estuary region and southeast coastal zone,and the decreased area located in the old estuary region.After 1993,the variational trend of the above two regions are reversed.The main reason is due to the influence of the Yellow River siltation and the ocean erosion.This study will provide suggestions on decision,making for the wetland protection of the Yellow River delta.
