在遥感地质中,对受线性构造控制的矿床,经影象解译后,可利用变量统计方法,将已知矿床地区与成矿有关的不同方向线性构造发育程度,作为训练组,与待测地区进行计算类比,得出与已知矿床最接近的地区,即可圈定为找矿远景区。先对待测地区划分网格,然后计算训练组均值,并以此为标准,与各待测网格内相应的变量值之差的绝对值求和,得到相似距离值(D)。表达式为: In the remote sensing geology, after the interpretation of the image, the ore-hosted deposits controlled by linear structure can use the variable statistical method to make the degree of linear tectonic development in different directions related to metallogenesis in the known deposit area as the training group, Areas to calculate the analogy, come to known deposits closest to the area, can be designated as prospecting prospect area. First, divide the grid into the test area, and then calculate the mean value of the training group, and use this as a standard to sum the absolute values ​​of the differences between the corresponding variables in each grid to be measured to obtain the similarity distance value (D). The expression is:
