%X The nature of BPH occurrence was investigated by means of fractal theory based on the systematic field investigation data of BPH occurrence.The results indicated:(1)BPH occurrence had a fractal property in fixed scale interval with the D value 0 7158,0 5212,0 2816 respectively.(2)The fractal dimension value of BPH occurrence was a new paramater expressing the distinction of occurrence degree in fixed scale interval,and the greater the fractal dimension value,the lighter the BPH occurance,and vice versa.(3)As D value showed a close correlation with aggregation degree,it could be used as an index for aggregation degree.(4) BPH occurrence possessed multifractal structure,and the related D q curve may have an application in the forecast of BPH occurrence.
