An Approach to Parameters Correcting Methods for Calculating the Climatic Productive Potenti-Alities of Crops in Mounain Areas

On the basis of the normal and temporary meteorological data (1957~1993) in Yuexi County of Dabie Mountain areas in west Anhui Province and with the help of recent research achievements, the three parameters of light, temperature and water corrected by topographic factors (sea level elevation, slope, slope direction) are obtained. As a result, a corrected scheme of calculating climatic productive potentialities of crops, which is suitable for Dabie Mountain areas concerning various altitudes, slopes and directions, is established.
