海岸线不同解译标志对解译结果的影响研究——以辽东湾北部海岸为例

Analysising the Different Results with Different Standards of Interpretation——Take the Northern Liaodong Bay for Example

海岸线提取对于海岸带综合管理,增强对自然灾害的抵御能力以及研究海岸环境变化都有重要的意义．应用遥感方法监测海岸线变化,提取海岸线,进行景观的分析具有范围广、精度高、可动态监测的特点．提取海岸线由于其解译标志不同,得出的结果差别很大．本文以辽东湾北部海岸为例,分析不同解译标志下,得出不同的海岸线位置．根据不同解译目的,探讨了如何选取解译标志的问题,并对解译标志选取过程中值得注意的问题加以了说明．

Locating the coastline is significative to the management of cosat zone, reinforcing the ability of resisting natural disaster, and it is very important for studying the change of environment in the coastzone. Using the way of remote sensing has many advantages： wider range, higher precision, dynamic inspection and so on. It will be different results with different interpretations of remote sensing. In this paper, we take the coast in the Northern Liaodong Bay for instance. We find that, when we use different interpretations, we get the different locations of the coastline. In the last of this paper , we analysis the relations between different interpretations and the results, and we make out the noteworthy questions in choosing the interpretations of remote sensing.
