摘要:
对秦岭地区太白山不同海拔高度秦岭箭竹进行小班调查,应用统计方法比较分析了地上部分主茎、一级侧枝和叶以及地下部走茎、根和芽的生物量。结果表明:1)海拔高度对秦岭箭竹种群个体和各功能构建的生长受环境因素影响较为明显。地下部分总生物量低于地上部分。阔叶栎林带(中温带)秦岭箭竹生长状况最佳; 2)秦岭箭竹地上部分构件生物量分配格局为主茎>一级侧枝>叶。一级侧枝和叶的生物量受环境气候因素较为明显,其主要原因可能是垂直气候带造成秦岭箭竹物候期推延所致。3)秦岭箭竹地下部分构件生物量分配格局为竹鞭>根>芽。竹鞭生物量最大,根生物量次之,芽生物量最小。
Abstract:
Based on the subcompartment investigation statistical methods,the biomass of Fargesia qinlingensis communities at different altitudes in Taibai Mountain of Qinling examined from the aspects of the main stem above ground, lateral branches and leaves, as well as underground parts. The results were as follows. 1). The influence of altitude on the individual plant of F. qinlingensis population and functional construction was significant. The total underground biomass was less than that of the ground. Growth situations of F. qinlingensis population in hardwood-oak forest belt in the warm temperate regions were the best; 2). The ground biomass was in the order of main stem > lateral branches> leaves. Lateral branch and leaf biomasses were mainly affected by climate factors, and the main reason was that vertical climate zones may lead to the delay of phonological phase of F. qinlingensis. 3). The underground biomasses were in the order of creeping underground stem>roots>buds. Stem biomass took up the largest, followed by root biomass, and bud biomass.
