| Abstract: | Four sample forest sites were selected in Wangqing Forestry Bureau and four management modes(follow-up management of the cutting-and-culturing forest,transformation of the low quality and low efficiency forest,cultivation of Pinus koraiensis forest for seed and timber production purposes,and cultivation of the precious tree species forest for large diameter timber production purpose)were monitored and analyzed in this paper.The results showed that for the cutting-and-culturing forest with follow-up management,the average DBH increment was 0.23 cm higher than CK,the stock increment per hectare was 3.70 m3higher than CK,the average annual stock increment per hectare was 1.85 m3higher than CK.For the low quality and low efficiency forest with transformation,the average DBH increment was 0.20 cm higher than CK,the stock increment per hectare was 3.60 m3higher than CK,the average annual stock increment per hectare was 1.80 m3higher than CK.For Pinus koraiensis forest for seed and timber production purposes with cultivation,the stock increment per hectare was 1.00 m3higher than CK,the average annual stock increment per hectare was 0.50 m3higher than CK.For the precious tree species forest for large diameter timber production purpose with cultivation,the average DBH increment was 0.10 cm higher than CK,the stock increment per hectare was 2.60 m3higher than CK,the average annual stock increment per hectare was 1.30 m3higher than CK.In general,four management modes not only significantly promoted the growth of forest trees,but also adjusted the structure of forest species and tree species,and increased the number of high-value forest trees.The effect was significant. |
