| 摘 要： | 对鱼龙林场厚朴与杉木人工混交林分标准地的初步调查表明，林分中杉木生物量大于厚朴，比例为３．２８：１，占乔木层总生物量的７６．６％；从生长过程看杉木胸径生长大于厚朴，杉木高生长与厚朴相近，杉木材积生长始终大于厚朴。１４年生时杉木与厚朴均未达数量成熟，材积生长潜力仍很大。

| Abstract: | The Preliminary investigat ions indicate that（1）the biomass of Cunninghamia lanceolata is largerthan that of Magnolia officinalis，their proportion is 3．28：1 and the former accounts for 76．6％of the totalbiomass of the arbor layer：（2） the dbh growth and volume growth of C. lanceolata are larger than those ofM. officinalis while the height growth of C. lanceolata is close to that of M. officinalis in the growth process：and（3）both species don't reach the quantitative maturity at the age of 14 years and thus their volume growthpotential is still very large. |
