On the basis of remote sensing technique ' s good characteristic with large - area , multi - time , multi - photograph variety , manifold abundant spectral information and high ground resolution , the fault tectonics frame , river geomorphy ( such as terrace , floodplain , shoal , etc ) and suspended load , etc . were explained after analyzed the fault tectonics , river geomorphy , characteristic in the tm image by gray bar statistics , primary component analyses , tm741 image integration , line convolve enhancement and model recognition etc . especially 9 piece of fault tectonics were explained in this thesis , in succession , the impacts of the factors severally were analyzed 遙感技術(shù)具有大范圍、多時(shí)相、多片種、多層次、含有豐富的光譜信息及具有較高的地面分辨率的特點(diǎn)。本文利用該技術(shù),運(yùn)用灰階統(tǒng)計(jì)特征分析和主成分分析、 tm741多波段融合、線性卷積增強(qiáng)、模型提取等一系列遙感解譯分析方法,分析了斷裂構(gòu)造、河流地貌(階地、漫灘、沙洲)及懸浮物等在tm遙感圖象上的影像特征,解譯出了安徽南部斷裂構(gòu)造格架、河流地貌和懸浮物的分布,并新解譯出了9條近東西向的斷裂。
