Soil samples were collected in Nanping,Fujian Province(117°57′E,26°28′N)and characteristics of soil inorganic nitrogen were investigated for different Chinese fir plantations of 11-,21-,28-,40-,88-year-old,compared with a mixed broad-leaved forest and a 2-year-old cleared area from an 86-aged Chinese fir plantation,which were both adjacent to the 88-aged Chinese fir stand.
在福建南平杉木林中心产区,选取11、21、28、40、88年生杉木人工林以及采伐迹地、杂木林为研究对象,研究不同年龄杉木林土壤无机氮的差异。

对福建南平市王台镇溪后村安曹下及邓窠的不同代数杉木林C库和C吸存的研究结果表明,1代杉木林C库总量为251。
3.
<Abstrcat>Based on the observed date, the efficiency of temperature and humidity of Chinese fir plantation has been analyzed.
结果表明:由于杉木林冠层的作用,使杉木林内形成了温度变化平缓,林冠层对地表温和土温的调节作用远大于气温;由于冠层的阻滞作用,使林内风速很小,乱流交换较弱,林木蒸腾蒸发的水气不易散失,造就了林内水气充沛、空气湿润的特征;杉木林内显热能的日平均波动在2%,杉木林内环境的潜热能占总温湿能的8%左右;杉木林具有这样的温湿特征是杉木林的结构特征、杉木林生理功能与环境相互作用的结果。
4) Chinese fir forest

2.
A comparative study was conducted for 2 a on soil biological activities of a 70-year-old fact-growingand high-yield Chinese fir forest (hillside), and a 32-year-old"young forest" of Chinese fir (hillside), whichwere originally occupied by broadleaved forests in Ancaoxia, Xihou, Nanping.
32a生杉木“青年林”土壤生物学活性下降则更为明显，说明从杉木取代阔叶林（头耕土）起，土壤生化活性及土壤肥力就存在明显下降现象，轮伐期缩短或林地连栽杉木代数增加，而不采取恢复地力措施，杉木林地地力衰退将更为明显。
