Coastline Monitoring by Remote Sensing and Change Analysis in Tumen River Estuary and the Adj acent Area
摘要
Abstract
Four yearsLandsat satellite images of 1985,1995,2005,2009 and one years GF-1 re-mote sensing satellite images of 2015 were used to analyze the changing characteristics of the past 30 years in the Tumen River estuary coastline.The results showed that:over the past 30 years,the whole coastline length shows an increasing trend,mainly caused by human development activities and sediment buildup,and the cumulative increase is 0.66 km.The ratio of artificial shoreline in-creased,but between 1985 and 1995,the coastline length decreased 3.8 km because the river course was diverted.Between 1985 and 2005,the deposition area of the coastal zone was larger than that of the erosion area,and the river course was diverted to make the deposition area in-crease 4.5227 km2 between 1995 and 2005.From 2005 to 2015,the erosion area was greater than the deposition area.From 2005 to 2009,the erosion area reached to 4.2037 km2 because the runoff had been reduced.The shoreline at the mouth had the greatest changes in migration and other re-gions were more stable.关键词
