长江安徽段河流地貌的遥感研究

Research on the River Geomorphology in Anhui Reach of the Yangtze River by Remote Sensing Techniques

利用2000年TM遥感图象,运用主成分分析、多波段合成、灰阶统计、地物波谱剖面分析等,解译了长江安徽段的河流地貌,作出了新的解译图,并在此基础上,分析了河流地貌中,阶地、漫滩、江心洲的分布和特征规律.

According to 2000 year＇s RS images, this paper explains the river geomorphology and draws the explanary picture after analyzing the primary components, multiband image integration, gray bar statistics, etc. Based on the analysis and explanation, the authors analyze the distribution and characteristics of the river geomorphology such as terraces, floodplains and shoals.
