| Abstract: | On the basis of introducing characteristic of BP network, a method that input factors and output factors of BP algorithm are standardly processed, and the problem is solved that in practice the differences between the output values and expectant values are too great to reach the demanding drill result. And the method of modifying study factor which can save drill time effectively is suggested. Further more these methods are applied to groundwater level forecast in irrigation district and satisfactory results are obtained. |
