摘　　要：为了探讨浙江大鹿岛木麻黄种群自引种以来经历了40多年自然演替后种群现状与发展动态,本研究采取典型取样法选择样地,应用每木调查法获得调查数据,运用"空间代替时间法"--径度级代替龄级的方法编制静态生命表,以此研究大鹿岛木麻黄种群的现状与发展动态。结果表明:大鹿岛木麻黄种群的年龄结构呈现典型金字塔形,种群呈现增长的趋势;不同海拔高度处木麻黄种群个体的平均生命期望值是中海拔>低海拔>高海拔;大鹿岛木麻黄种群的存活曲线属于Deevey-Ⅲ型曲线,其死亡率与环境阻力呈正相关性,种群表现出幼龄树生长不稳定,中龄树和成龄树稳定,老龄树衰退的特点。To understand the current situtation and the trend of the Casuarina equisetifolia population on the big deer island which has undergone the natural succession for more than 40 years,a systematic vegetation survey was conducted to measure each Casuarina equisetifolia in the sample plot.The life table of Casuarina equisetifolia population on the big deer island was studied by spatial method instead of time method,and the current situtation and the trend were studied at the basis of the life table.Result shows that： The age structure of Casuarina equisetifolia population is pyramidal and belongs to increasing type;the individual viability in different altitude.
