基于高分辨率遥感影像的铜盘岛土地利用检测

Land Use Detection of Tongpan Island with High Resolution Remote Sensing Images

以2012年资源三号和2016年高分二号高分辨率影像为数据源,采用监督分类与矢量化相结合的方法提取了铜盘岛的开发活动信息,并从面积变化及地类转移分析了土地利用变化.结果表明,近5年房屋建设、港口码头、道路广场、土石开采和其他土地面积有所增加,其中面积增加最大的是土石开采,约增加了0.52ha,主要由林业用地转换而来.同时,林业用地、仓储建筑和基础设施的面积有所减少,其中面积减少最大的是林业用地,近5年减少了0.52ha,主要转换为道路广场、房屋建设和土石开采等.

Basing on the data of 2012 ZY-3 and 2016 GF-2,the development activities of Tongpan Island were extracted by the combination of supervised classification and vectorization,and analyzed land use changes from area changes and land class transfer.The results showed that in the past five years,building construction,port terminal,road square,rock mining and other land areas increased.Among them,rock mining changed significantly,which increased about 0.52 ha,mainly was due to the conversion of forest land.Meanwhile,the area of forest land,storage building and infrastructure reduced.The largest reduction was forest land,which reduced by 0.52 ha in the past five years.it was mainly converted into road square,building construction and rock mining.
