土地利用动态监测中GIS与RS一体化的变更地块判别方法

GIS & RS integration:land parcel change recognition method in land use dynamic monitoring

论文针对土地利用动态监测面临的实际情况 ,提出一种GIS与RS一体化的变更地块判别方法。这种方法以矢量图斑为研究对象、以GIS的地理信息与RS的遥感影像信息为特征来源 ,提取图斑的特征向量。在设计识别方法时 ,将土地利用变更地块的识别变通成对标准地类的识别 ,同时引入“落入”、“误判高发区”的概念以降低变更地块的漏判率。经试验 ,这种基于GIS与RS一体化变更地块判别法基本可替代土地利用动态监测中的人工判读工作。

According to the particularity of land use dynamic monitoring,this paper puts forward a kind of method for land parcel change recognition by GIS & RS Integration.The research unit of this method is polygon.The feature source was from geographical information in GIS and remote sensing images.In addition,according to the particularity of the type and the target of discriminance,this paper identifies two changes.One is to change distribution question into non distribution question,another is related to the grimness the condition of discriminance in order to reduce omission error.Finally,the test presented can improve distance discriminance method based on GIS & RS integration that can replace artificial recognition in land use dynamic monitoring.
