通过计算建立了实生湿地松林的地位指数曲线,新方程与现有的天然次生林分的方程相似。地位指数作为在特定的指数或基础年龄下所期望的成熟林分的优势高或亚优势高,常被用作估计某一区域的木材生产潜力。在不同的林分状况和地理区域,地位指数方程或曲线已被应用于湿地松(Pinus ellio ttij var elliottii Engelm)林分(Bailey etal 1982,Bennett 1970,Bennett etal 1959,Schumaeher and Coile 1960,Zarnochand Feduccia 1984)。在皆伐过的林地上植苗
The position index curve of the native wetland pine forest was established by calculation. The new equation is similar to the existing natural secondary forest equation. The status index, which has high or sub-superiority as a mature stand as expected under a particular index or base age, is often used as an estimate of the timber production potential in a particular area. The status index equation or curve has been applied to the Pinus ellio ttij var. Elliottii Engelm stand (Bailey et al 1982, Bennett 1970, Bennett et al 1959, Schumaeher and Coile 1960, Zarnochand Feduccia 1984). Planting seedlings in cleared forest
