摘要:结合竹类植物在浙西红壤丘陵的规模化应用, 采用固定样地长期连续观测的调查方法研究新造毛竹Phyllostachys pubescens 林林分结构演替规律及影响因子。研究表明, 新造毛竹林立竹度和立竹胸径是林分结构年际变化的主导因子, 立竹枝下高是从属因子;造林后第1～ 5 年竹林地下鞭系主要分布于10 ～ 20 cm 土壤区段, 随着造林年限的延长, 20 ～ 30 cm 土层区间为主要分布区;鞭径随造林年限逐年增粗, 第4 年趋于稳定。平均鞭节长相对稳定;活侧芽数与总鞭长和平均鞭节长极显著相关, 随造林年限总体呈线性增加趋势;立地类型、林模式、抚育措施、母竹质量和初植密度是竹林林分结构状况的主要影响因子。建议在发展毛竹资源时采用混交造林模式并增加初植密度。图2 表6 参11

Abstract:Long-term fixed site observation was conducted based on the large-scale planting of bamboos in the hilly areas of western Zhejiang to study the succession rule and main factors affecting the components of young stands of Phyllostachys pubescens .The results showed that density and DBH were the dominating factors for the interannual changes of component ;LH was the subordinating factor .After one-to-five-year planting , the subterranean stems of bamboo were mainly distributed in 10 -20 cm deep soil layer .With the prolonging of the planting years , the 20 - 30 cm deep soil layer became the main distributing layer for the subterranean stems .The diameters of the subterranean stems were becoming larger and larger until they were stabilized in the fourth year .The average length of a stem joint was relatively stable .The number of living sprouts and the total length of subterranean stem were significantly relative to the average length of a stem joint , which took on a tendency of linear increase .The land types , afforestation modes , cultivating measures , quality of mother bamboos and the original planting density were the main influential factors for the components of the bamboo forest .It is suggested that the mixed planting mode should be adopted and the original planting density should be increased .[ Ch , 2 fig .6 tab .11 ref .]
