摘要
基于多时相中高分辨率遥感影像,利用RS和GIS平台获取海岸带和近海资源环境信息是当前遥感技术应用领域一大热点。区别于直接从地形地貌学、海岸动力学角度对陵水海岸类型的调查和判读,研究利用1987—2017年多时相遥感影像,结合数字图像处理技术、GIS技术和目视解译标志定量获取陵水近30年陵水岸线空间位置变化和双湖区(新村潟湖、黎安潟湖)面积变化信息。与此同时,对影像所反映特征信息进行针对性的野外考察,解译陵水外沿海岸20个侵蚀岸段并探讨双湖区演化规律,最终为准确评估陵水海岸带资源环境承载力提供参考依据。
Based on multi-temporal medium and high resolution remote sensing images,using RS and GIS platform to obtain coastal zone resources and offshore environmental information is a hot spot in the application of remote sensing technology.Different from the direct investigation and interpretation of Lingshui coastal types from the perspective of topography and geomorphology or coastal dynamics,this paper studied the quantitative acquisition of the shoreline change and two lagoons’area change in recent 30 years with multi-temporal remote sensing images from 1987 to 2017 combining with digital image processing technology,GIS Technology and visual interpretation marks.At the same time,the characteristic information reflected by remote sensing images was investigated in the field.Finally,this study analyzed the evolution of Lingshui shoreline and the change of two lagoons’acreage.Finally,it provides a reference basis for accurately evaluating the carrying capacity of resources and environment in Lingshui coastal zone.
