　　野外进行的二维水动力弥散试验，大多采用在人工一维流场下，示踪剂瞬时投放的方法。由于水动力弥散方程的复杂性，不易获得弥散参数的精确解析解，为了解决这个问题，国内外很多学者已经开发出多种计算方法，该文首先总结了标准曲线配线法、直线解析法、图解分析法、数值模型法和智能算法等算法各自的优点和局限性，然后以一次现场试验为例说明计算方法的应用。旨在为试验者在不同的试验条件下，选择合适的计算方法提供参考。

Most field two-dimensional hydrodynamic dispersion tests are conducted in the condition of man-made one-dimensional flow field and the tracer is put in instantly .It is difficult to obtain dispersion parameters analytical solution accurately on account of the complicated hydrodynamic dispersion equa -tions.In order to overcome this problem, many calculation methods have been developed throughout the world.Firstly, the paper points out the merits and limitations of five methods including the standard curve fitting method, linear analysis method, graphic analysis method, numerical model method and intelligent algorithm, then the application process is illustrated by one field test .It provides the references for testers to adopt appropriate algorithm in different test conditions .
