| 摘 要： | 以潮关西沟林场封禁25年后的荆条灌丛为研究对象,选择沟谷、阳坡、半阳坡和半阴坡4个生境条件,分析了荆条种群的年龄结构,编制了静态生命表,绘制了存活曲线。研究结果表明,不同生境自然恢复的荆条种群年龄结构均属于进展型,幼龄个体多,老龄个体少,其中以阳坡种群密度最大,不同生境荆条种群的存活曲线均接近DeeveyⅡ型,荆条种群恢复状况良好。

| Abstract: | This paper studied Vitex negundo community on the sunny,valley,semi-sunny and semi-shady slopes after 25 years' closure for reforestation in Chaoguan Xigou Forest Farm,analyzed the age structure,life table,and survival curve of the population.The results showed that Vitex negundo population in the area belonged to progressive type,with more young and less old individuals.Among the three habitats,sunny slope had the highest population density.The survival curve of Vitex negundo population was close to Deevey Ⅱtype,Vitex negundo population recovery better. |
