摘要:
[目的] 探究桂西北杉木人工林生长过程中生物量和生产力的积累过程及其变化规律,为该区域杉木人工林经营管理提供依据。[方法] 以广西南丹县杉木人工林为研究对象,采用样地调查与生物量实测方法,研究了不同林龄(5、10、15、20年生)杉木人工林的生物量、年净生产力及其分配特征。[结果] 不同林龄乔木层生物量在19.13~152.14 t·hm-2之间,随林龄增加而增大。各林龄乔木层生物量的增长量表现为:10~15年生(51.81 t·hm-2)>5~10年生(42.47 t·hm-2)>15~20年生(38.73 t·hm-2)。随着林龄的增加,杉木人工林生物量中干材所占比例逐渐增大,而树叶和树枝所占比例逐渐减小。5、10、15、20年生杉木人工林林下植被生物量分别为1.93、1.12、1.38、2.01 t·hm-2,其中灌木层依次占29.02%、44.64%、47.10%和40.30%,草本层依次占70.98%、55.36%、52.90%和59.70%;凋落物层生物量依次为1.30、2.04、4.03、6.15 t·hm-2,随林龄增加而显著增大。杉木人工林乔木层年均净生产力依次为3.83、6.16、7.56、7.61 t·hm-2·a-1,其中干材组成比例(37.43%~66.24%)随林龄增加而增大,树叶和树枝组成比例(5.12%~16.49%和9.20%~21.20%)则呈现相反的变化趋势。[结论] 杉木人工林乔木层生物量随林龄增加而逐渐积累,其中干材所占比例随林龄增加而增大,树叶、树枝和干皮生物量所占比例随林龄增加而下降,树根生物量所占比例波动较小。桂西北杉木人工林具有较高的生物生产力水平,其不同林龄年均净生产力高于国内多数区域杉木人工林。
Abstract:
[Purpose] In order to study the accumulation process and its variation of biomass and productivity during the growth of Cunninghamia lanceolata plantation, and to provide a scientific basis for the management of C.lanceolata plantations.[Method] The biomass, productivity and distribution characteristics of C.lanceolata plantations (5, 10, 15 and 20 years old) in Shankou Forest Farm of Nandan County was studied through sample plot investigation and biomass measurement.[Result] The biomass of the tree layer increased with the increasing stand age, ranging between 19.13 and 152.14 t·hm-2. The biomass increments were 51.81, 42.47 and 38.73 t·hm-2 for stand ages of 10-15, 5-10 and 15-20, respectively. With the increase of stand age, the proportions of biomass allocated to stem gradually increased, while those allocated to leaves and branches decreased. The biomass of undergrowth vegetation was 1.93, 1.12, 1.38 and 2.01 t·hm-2 for 5, 10, 15 and 20 years old plantations, respectively, with the shrub layer accounting for 29.02%, 44.64%, 47.10% and 40.30% of the biomass, and the herb layer accounting for 70.98%, 55.36%, 52.90% and 59.70%, respectively. The biomass of the litter layer reached 1.30, 2.04, 4.03 and 6.15 t·hm-2, respectively. The annual net productivity of the tree layer were 3.83, 6.16, 7.56 and 7.61 t·hm-2·a-1 for the 4 stand ages, respectively. The proportion of net productivity of timber (37.43%-66.24%) increased with stand age, while the proportion for leaf (5.12%-16.49%) and branch (9.20%-21.20%) showed the opposite trend.[Conclusion] The biomass of the tree layer increased with stand age in C.lanceolata plantations. The proportion of the economic biomass (timber) increased with stand age while it decreased in leaf and branch and varied slightly in root and bark. The C.lanceolata plantation in Northwest Guangxi had high biological productivity, with net productivity of different ages of stands exceeding those of most C.lanceolata plantations in other regions of China.
