摘 要：
贵州省山高坡陡、地块破碎,地物光谱特征复杂,受“同谱异物,同物异谱”的干扰大。在应用中巴地球资源卫星数据进行贵州省森林资源调查研究中,单纯靠传统分类方法难以达到理想的效果。笔者主要采用非线性波段比等方法,有效地扼制了干扰,通过灰度值、光谱剖面曲线等分析,总体上提高了图像的对比度及各种地类差异,从而提高了计算机分类的精度。

摘 要：
Because of the high mountains,steep slope and fragmentized fields,the spectrum characteristic of target on the ground in Guizhou province is complicated and is heavily disturbed by the phenomenon of “same spectrum different target” and “same target different spectrum”.It is found that is difficult to reach the ideal result only by the traditional classifying method in the study on the application of CBERS data in the forest resources investigation of Guizhou province.Using the method of non-linear band ratio in the study effectively reduces the disturbance.Analyzing through grey value,spectrum sectional curve,etc,has generally strengthened the contrast ratio of the image,and the differences between the various land-types,thus improved the classifying precision.
