介绍了分形理论和方法近年来在成矿规律与成矿预测中的应用情况。通过研究分形模型及其曲率，提出了一种求分维数的新方法．该方法求出的分维数比用传统方法求出的分维数更精确（即估计误差更小），并且具有许多优点。最后通过例子说明分形理论在实际问题中应用的方法及步骤，并解释了分维数的实际意义 The application of fractal theory and method in metallogenic regularity and metallogenic prediction in recent years is introduced. By studying the fractal model and its curvature, a new method to find the fractal dimension is proposed. The fractal dimension obtained by this method is more accurate (that is, the estimation error is smaller) than that obtained by the traditional method, and has many advantages. Finally, an example is given to illustrate the application of fractal theory in practical problems and steps, and explain the practical significance of fractal dimension
