以东华理工大学抚州校区及附近区域为研究区，采用线性光谱混合模型进行混合像元的分解。对线性光谱混合模型采用两种方法进行解算：一种是全约束最小二乘法；另一种是IDL自带的寻优函数来实现非负最小二乘法，并通过归一化使得总和为1，结果表明后者优于前者。

The study area of this paper is on East china institute of technology and nearly.This select linear model of unmixing model. Solved by two methods:One is the fully constrained least squares method;the other is the optimization function of IDL to realize the negative least squares, in the meantime by means of normalization.The latter is no doubt better than the former.
