| 摘 要： | 我们对江西大岗山丘陵区杉木人工林生产的生态特性、净生产量及生产力等进行了研究分析,为寻求杉木人工林合理的经营途径,提供科学依据。一、林分概况试验是在江西大岗山山下林场陂元杉木人工林中进行的。该地位于中亚热带东部,罗霄山北端武功山余脉,属丘陵地形。调查林分为12年生的杉木人工林,初植密度为1530—3345株/ha,土壤为页岩上发育起来的黄红壤,土层80—150cm,腐殖质层(A+AB)厚度为10—50cm,海拔高度130—220m,坡向东南,坡度30°,主要林下植被为:杜茎山、紫珠、柃木、黄瑞木、芒萁、狗脊蕨等。

| Abstract: | This paper is based on the 12 year-old Cunninghamia lanceolata at Dagang mountain in Jiangxi provience, 41 piots and 41 average trees were studied. It dealed with ecological characteristics of Cunninghamia lanceolata plantation, the regulation of density effect in different site conditions, biomass as well as productiviety afforestation. According to the method of b value analysis, the results show that the primary and management density in low index of position area must be more than high index of position area, the difference is 600 tree/ha. |
