Abstract: Two phases, deterioration phase and instauration phase, were marked off according to changes of forest management policy, characteristics, forest quantity, quality and structure in China. From 1950 to 2003, 130.57×10.8m3 timber was harvested and forest area and volume rose. Due to the underdeveloped forest philosophy, such as more importance to cutting and slight to cultivating, an unclear definition for forest classification management, an undefined aim for management structure adjustment, a focus of timber request and an ignorance of natural laws of forest growth, it makes the forest structure changed greatly with the proportion of natural forest area decreased by 30.6%, natural forest volume decreased by 9.4%, timber forest area decreased to 46.52%, timber forest volume decreased to 45.57%. The proportion of young and middle-aged forest are a occupied 67.9%. The coniferous forest area and volume also decreased. Because of the highintensity cutting and short selective cutting period, the forest quality in China is still not high, even though resumed gradually in the second phase. The forest volume per unit reached only 84.73 3/hm2 The forest of low crown density (0.2 to 0.4) covered 34.41%, the average diameter at breast diameter was 13.8 cm. Only 42.22% of the stand was well-grown. The proportion of the artificial forest area was bigger, but the proportion of young and middleaged forest was 7740% and the average volume per unit was only 46.59 m3/hm2. The forest management theory and practice should be analyzed according to the resource status. Forest management theory, forest property optimization, forest resource classification and management technology should be endowed a high priority.
