摘　　要：主要利用图像融合技术和人机交互的解译方法,通过对CBERS-02B星的2.36m高分辨率HR影像与2007年29.5m分辨率的TM影像融合,结合2007年的土地利用数据和1:5万基础地理数据,以四川省攀枝花市盐边县为例进行线状地物的提取及扣除工作,并对其解译精度进行客观评价与分析。结论表明:与TM影像融合后的HR高分辨率影像可以进行线状地物的提取及扣除工作,解译精度基本上可以满足全国生态环境监测与评价的工作要求。This paper uses the image fusion technology and human-computer interactive interpreting and analysing method to deduct linear features by the fusion of CBERS-02B 2.36m high resolution HR images and 29.5m resolution TM images of 2007,combined with the land use data and 1：50000 basic geographic data of 2007,taking Yanbian County,Panzhihua City,Sichuan Province for example;and then to evaluate the accuracy of its interpretation and analysis objectively.Conclusions indicate that the fusion of TM images（resolution 30m） and HR high-resolution images can extract and deduct the linear features and its interpretation accuracy is basically to meet the national ecological and environmental monitoring and evaluation requirements.
