摘　　要：本研究在汪清林业局选定4块样板林,分别对采育林后续经营、低质低效林改造、红松果材林培育、珍贵树种大径级材林培育4种经营模式进行检测和分析。结果表明:采育林后续经营样地平均胸径增长量比对照高0.23 cm,公顷蓄积增长量高3.70 m^(3),平均年生长量高1.85 m^(3);低质低效林改造经营样地平均胸径增长量比对照高0.20 cm,公顷蓄积增长量高3.60 m^(3),平均年生长量高1.80 m^(3);红松果材林培育经营样地公顷蓄积增长量比对照高1.00 m^(3),平均年生长量高0.50 m^(3);珍贵树种大径材林培育经营样地平均胸径增长量比对照高0.10 cm;公顷蓄积增长量高2.60 m^(3),平均年生长量高1.30 m^(3)。总体上4种经营模式不但明显促进了林木生长,而且还调整了林种结构、树种结构,增加了高价值林木数量,效果显著。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 m^(3)higher than CK,the average annual stock increment per hectare was 1.85 m^(3)higher 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 m^(3)higher than CK,the average annual stock increment per hectare was 1.80 m^(3)higher than CK.For Pinus koraiensis forest for seed and timber production purposes with cultivation,the stock increment per hectare was 1.00 m^(3)higher than CK,the average annual stock increment per hectare was 0.50 m^(3)higher 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 m^(3)higher than CK,the average annual stock increment per hectare was 1.30 m^(3)higher 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.
