| 摘 要： | 先锋树种马尾松种群的生存状态是南方红壤侵蚀退化区开展水土流失治理措施的关键前提。通过对长汀水土流失区侵蚀劣地"小老头松林"的样地调查,基于种群统计的方法,建立年龄结构图和静态生命表、绘制存活曲线和生存分析函数、应用时间序列模型,对侵蚀退化生境马尾松种群动态变化过程开展研究。结果表明:马尾松种群年龄结构呈基部极宽、顶部狭窄的金字塔型,幼龄个体数量丰富但续存率低,成年个体很少,种群增长性低;死亡在各个生活史阶段均有出现,个体存活曲线属于Deevey-Ⅱ型,种群处于动态稳定状态;种群在幼龄期和壮龄期的生存状况不稳定,新生苗和壮龄期个体死亡密度大;种群时间动态预测显示,未来成年个体数量将增多,种群呈增长趋势。今后的森林生态管理中,可针对幼龄个体和壮龄成年个体采取抚育措施,提高小老头松林的生态效益。
