Abstract: The experimental results of transforming the artificial forest of Chinese pine to the mixed broadleaf pine forest in the hilly areas of western Liaoning province for seven years were reported in the paper. The results showed that by means of cutting down the pine trees line and replanting on each other the nitrodron fixing trees species the structure and components of pure artificial forest of Chinese pine with high density could be changed into the mixed broadleaf pine forest. The mixed forest was better for growth of the trees owing to change of ecological condition and for ecological fuction of containing water and fixing the soil.
