遥感技术在海岸带环境地质调查中的应用--以山东省沾化县北部沿海地区为例

摘要

海岸带是海洋和大陆交互作用的地带，作为人类生存发展的重要区域，其环境地质问题非常突出。该文通过遥感技术手段，利用多期遥感数据解译成果，根据需要对特殊信息进行专题信息提取，掌握研究区海岸带变迁规律和地表覆被时空变化特征，完成对复杂海岸带的环境地质调查工作。%Coastal area is the interaction zone between ocean and continent.As an important area for human survival and development,geological environmental problem is very prominent.By means of remote sens-ing techniques,using multi temporal interpretation remote sensing data,according to the need for special information,thematic information has been extracted.Change rule and spatial and temporal variation char-acteristics of surface cover have been grasped.On these basis,environmental geological survey work in complex coastal zone has been completed.
