摘　　要：华北陆块北缘作为中国5个铀成矿省之一,铀成矿潜力巨大,分布有多种类型铀矿床,其特征是否存在共性并用以指导找矿,值得进一步研究。文章通过目视解译、盒计维度、多重分形谱等方法对已知矿田区图像纹理进行研究发现,矿田区在不同尺度目视解译出的多方向构造特征不同,相较于外围邻区具有更大的分形维度值及更对称的奇异谱形态,对预测区综合研究也得到一致结论。这说明图像纹理可以用于成矿条件评价,对该区远景预测具有一定指导意义。As one of the five uranium metallogenic provinces in China, there are various types of uranium deposits and great uranium prospecting potential in the northern part of North China Landmass, whether there is common feature among these deposit which can be used to guide the exploration of uranium deposits need further study. In this paper, visual interpretation, calculation of box dimension and a -f（a） multifractal spectra were used to study the texture features of remote sensing image in ore - fields, and found that ore - fields is with multi - direction line structure features at different scale in visual and larger value of fractal dimension and more symmetric multifractal spectra than that of the image of the neighbor area. Research on the prediction areas show the same conclusion, therefore image texture can be used for metallogenic conditions evaluation and can used as guide role in prospect prediction.
