in the mid levels fir forest cutover camp for the benefit of Fokienia hodginsii Pinus massoniana Schima superba pure forest and mixed forest ,after 12 years of operation and management ,to different forest growth and soil properties were investigated and analyzed .Results showed that 12 years old of Fujian cypress pine Schima superba forest stock volume ,biomass ,soil fertility ,respectively ,compared with the pure Fokien‐ia hodginsii Schima superba and Pinus massoniana forest stand volume increased 8 .09% and 10 .35% ,106 . 78% ,improve the total biomass of the stand to 8 .21t/hm2 35 .98t/hm2 ;mixed forest soil physical and chemi‐cal properties are compared with the pure forest were somewhat improved .%在镇办半山林场杉木采伐迹地营造了福建柏马尾松木荷纯林、混交林，经过12年的经营管理，对不同的林木生长效果和土壤性质进行了调查分析。结果显示：12年生的福建柏马尾松木荷混交林的林分蓄积量、生物量、土壤理化性质，分别比福建柏马尾松木荷纯林的林分蓄积量提高8．09％、10．35％、106．78％，林分总生物量提高8．21～35．98t／hm2，混交林的土壤理化性质也比纯林均有所提高。
