通过对陆地卫星MSS资料,即140-37幅(1975年10月4日)和141-37幅(1977年7月14日)进行光学,数字计算机处理以及目视判读,提出了四川若尔盖高原地区裸露型沼泽泥炭地的影像分类方案,并分析了各类泥炭地的影像,地貌,植被以及泥炭厚度特征,探讨了它们之间的关系。在野外进行了地物光谱测量和影像分类的验证工作。通过分类研究,较准确地圈定了泥炭地的范围,同时做了资源区划。
Through the optical, digital computer processing and visual interpretation of the Landsat MSS data, that is, 140-37 (October 4, 1975) and 141-37 (July 14, 1977), the Zoige Plateau region of Sichuan The image classification scheme of the bare swamp peatland was analyzed. The images, topography, vegetation and peat thickness characteristics of various types of peatlands were analyzed, and the relationship between them was discussed. In the field of land surface spectral measurements and image classification verification. Through the classification of research, more accurately delineated the scope of peatlands, while making the resource division.
