The Study on Environmental Evolved Characteristic of Sandy Coast
In order to study the evolved characteristic of sandy coast in Hebei Province, the paper analyzed costal information by Remote Sensing technology from landform maps and remote sensing images from 1956 to 2007.It studied the evolvement characteristics and the reasons of sandy coast deeply.And it also analyzed the evolvement infections to the nearby coast of the sandy engineering.The results showed that the characteristic was erosion condition in sandy coast.There were several different evolved processing in different area from 1959 to 2007.In the region between Daihe River and Tazigou, the highest erosion speed was 3.45 m/a by the coastal current and wave between Daihe River and Yanghe River.The section was deposited into the ocean with the speed of 1.29 m/a by the cultivation ponds building in Bohai Sea farmland between the Yanghe River and Dapuhe River.In the region between Tazigou and Langwokou River, the beach had been eroded about 373 m with the speed of 13.32 m/a by 2007.And the section was eroded offshore more serious with the distance of 610 m and the speed of 21.79 m/a from the north of Luanhe River.In the region between Langwokou River and Daqinghe River, the average erosion distance was about 370 m with the speed of 13.21 m/a in Shegang sandbar.And it was eroded back to mainland about 164 m with the speed of 8.20 m/a.And it was about 504m with the speed of 18.00 m/a.
