遥感图象处理技术在土壤分类中的应用──以阜康地区为例

Application of Image Processing in Soil Classification

图象处理是一门新兴的多学科技术，在各个学科得到了广泛的应用．在综合前人工作的基础上，本文尝试了一种新的工作方式──组合式训练区分类。其指导思想是：尽量多地利用图象处理技术，以增加结果的客观性和可重复性．具体做法是：将监督分类和非监督分类结合起来．工作程序为，首先，进行图象预处理，包括图象配准，图象几何校正．第二，进行非监督分类，将分类结果制成训练区图。第三，用训练区图进行监督分类．这种方法能进一步地利用图象处理技术，从而使结果能兼顾监督分类与非监督分类的长处。本文使用此方法制作了阜康市部分地区的土壤图，取得了令人满意的结果。

Image processing is A new and multidisciplinary technology.It is widely applied in many discipline. After synthesizing the relevent data,the paper attempt a new method:combination training area classification.The train of thought of the paper is to try the best to use the technology of image processing,and to make the result. have more objectivity and repeatablity. The specific method is to combine the supervised classification and unsupervised classification. First, the task is image preprocessing, include image registration,geomotric correction.Second,the unsupervised classification.is used to produce the map of training area. Third,the map of training area is used in supervised classification.The method can go a step further to apply image processing technology,and then,the result can have the advantage of supervised classification and unsupervised classification.The paper use the method to make a soil map of part of Fu Kang district,and obtain a satisfactory result.
