MSS图像中泥炭沼泽的识别标志及其形成机理

以若尔盖地区为例,通过图像处理、影像分析,建立了泥炭沼泽区在Landsat MSS4个波段图像上皆呈低反射率、暗色调的影像识别标志,根据识别标志准确地圈定了泥炭资源区的范围;通过地物光谱实测和论证分析,论述了该影像识别标志的形成机理,指明了其可靠性和普遍适用性,为遥感在泥炭资源调查中的应用指出了技术关键和科学依据。

THE IDENTIFICATION KEY OF THE PEAT BOG IN MSS IMAGES AND ITS FORMING MECHANISM

Taking the case of Ruoergai region as an example, and by means of image processing,in formation extracting and imaga analysing, the writer pointed the identification key of the peat bog area inimages of all four MSS bands, which shows a dark tone with lower reflectance. Accordingic the key, thedistribution range of peat resoures in the region was exactly located. Using the spectrum measorements ofground body and the correlation analysis,the forming mechanism, reliability and universal suitability of theidentification key were expounded. The technical key and scientific basis were provided for the application ofremote sensing technique in surveying peat resources.
