摘　　要：为进一步推广国产卫星遥感影像数据在国土资源行业中的应用,针对土地利用监测与现状变更调查业务需要,探索"高分二号"(GF-2)卫星数据在土地利用动态监测与现状变更调查工作中的适用性及其潜力。以四川隆昌县金鹅镇为研究区,通过定性、定量评价原始影像数据质量,对比分析同级数据,结合多方法提取变更信息,从不同角度测试其变化监测能力。结果显示,GF-2卫星数据地物清晰,光谱信息丰富,目标解译性较好,影像效果优于"高分一号"(GF-1)和SPOT6数据;主成分分析法和光谱变异法的结合可快速发现影像上的变化信息,GF-2卫星影像能满足土地利用变更监测的需求,具有较大潜力及价值。In order to further promote the application of domestic satellite remote sensing image data in China＇s national land industry,according to requirements of the land use change survey and status monitoring,this paper explores the applicability and potential of GF-2 satellite data in the investigation of land use dynamic monitoring and current situation change survey.With Jine town of Longchang county in Sichuan province as the study area,the quality of the original image data is evaluated qualitatively and quantitatively.Comparing data with the same level ones and combining with multiple methods to extract change information,monitoring ability are tested from different angles.The results show that GF-2 satellite data has clear features,rich spectrum information,better target interpretation,and superior image effect to GF-1 satellite and SPOT6 data.The combination of principal component analysis and spectral variation can find the change information in the image quickly.Therefore,GF-2 satellite can meet the needs of land use change monitoring,and has a certain potential and value.
