| 摘 要： | 油松(Pinus tabulaeformis)是黄土高原重要的乡土树种,在修复与保护当地环境中有着举足轻重的作用.应用样方法调查黄土高原子午岭马栏林区天然油松林的种群结构,采用编制静态生命表及绘制存活曲线的方法,分析天然油松的动态变化.结果表明:油松种群结构呈反"J"型分布,种群年龄结构属于增长型;高度结构呈规则的倒金...

| Abstract: | Pinus tabulaeformis is an important endemic species in the Loess Plateau,and it has a pivotal role in improving local ecological environment. In this paper,the types of P. tabulaeformis population structure were analyzed with sampling method. The laws of dynamic change of P. tabulaeformis population were analyzed using the static life table and survival curve. The results show that the P. tabulaeformis populations were in an inversed J-shaped distribution,and their age structure belonged to a typical growth... |
