海平面上升的淹没效应和岸滩冲淤对潮间带湿地面积影响的分离估算
Separation Estimate of Beach Erosion and Deposition on Intertidal Wetland Because of Sea Level Rise and Normal Deposition
摘要
Abstract
Swamping effect of sea level rise causes intertidal wetlands loss,while sedimentation could make the intertidal area continued growth.The actual changes of the intertidal wetland depend on these two factors.Based on the repeated measurements of three fi xed cross-section elevation and combined sea level rise rate and the slope of the intertidal zone,this paper is trying to distinguish the impact of these two factors to the development of the intertidal zone.The results show that,sedimentation caused Eastern Chongming intertidal wetland area increased by 1.79km2（average 0.36 km2/a） from 2005 to 2010,while swamping effect of relative sea level rise led to Eastern Chongming intertidal wetland area loss of about 0.44~0.64 km2（0.09~0.13km2/a）,and the actual increase of the intertidal wetland area was 1.15~1.35km2（0.23~0.27km2/a）.In the coming decades,the global sea level rise will accelerate and the sediment from Yangtze River to the sea will further reduce,so the net deposition rate of Eastern Chongming intertidal zone may decline further,and the development and utili-zation of Chongming wetlands will face new challenges.关键词
