天津市海岸线现状

Research on the coastline of Tianjin

海岸线是陆地与水体交界的重要标识,海岸线的位置和类型是海岸带生态环境修复的基础数据。本文以天津市海岸线为研究对象,通过遥感解译与实地验证相结合的方式,对天津市海岸线位置和分类进行了研究,结果显示,目前天津市海岸线长度约366.92 km,其中港口和围海造陆岸线281.78 km、围海养殖岸线22.92 km、海堤岸线25.77 km和人工河口岸线36.45 km,自然岸线数值趋近为零,围海造陆及港口岸线所占比例达到了76.80%。由于围填海等人类活动,岸线较2000年增加了143%。

The coastline is an important indicator of the boundary between land and water bodies.The location and type of coastline is the basic data for the restoration of the ecological environment in the coastal zone.This article takes the Tianjin coastline as the research object,and researches the location and classification of the Tianjin coastline through a combination of remote sensing interpretation and field verification.The results show that the current coastline length of Tianjin is approximately 366.92 km.The line is 281.78 km,the sea-farming shoreline is 22.92 km,the seawall shoreline is 25.77 km,and the artificial river port line is 36.45 km.The value of the natural shoreline is approaching zero.Due to human activities such as reclamation,the coastline has increased by 143%compared to 2000.
