Abstract: A location test was made in Zhangbei county, on the Bashang Highland in the northern part of Hebei province from 1987 to 1989 in order to get the coefficients of both water consumption and precipitation utilization in this region, and a great deal of data was accumulated. After a series of parameters were corrected, a budget estimation formula for productive potentialities suitable to local conditions was established with FAO Wageningen method. It was proved in the field test that the potential value was reliable and feasible. The productive potential value of natural precipitation, and coefficients of both water consumption and precipitation utilization were calculated On this basis the different climate types and the utilization situation of precipitation throughout the year in this region were analysed. Therefore, the theoretical basis was provided for effective development and utilization of the precipitation resources in this region.

Key words: Bashang Highland, Productive potentialities, Water consumption coefficient, Precipitation utilization coefficient
