摘  要:
以邵阳市林业科学研究所内12年生醉香含笑为研究对象,对其生长规律进行分析。结果表明:醉香含笑的胸径、树高生长基本呈现"慢-快-慢"的规律,材积生长为典型"J"型规律,这是由于该醉香含笑林分尚未达到数量成熟;标准木的生物量为49.44 kg,含水率为52.24%,林分生物产量为79.16 t/hm2;该林分的净生产力为6.60 t/(hm2·年)。

摘  要:
The growth rhythm of 12 years old Michelia macclurei in Shaoyang Forestry Institute was analyzed. The result showed that the DBH and height growth presented the rule of "slow-fast-slow",and the growth of volume' s rule was"J shaped"curve. This was because the forestry hadn' t reached the quantitative maturity. The biomass of model tree was 49. 44 kg,and the moisture content was 52. 24%. The biological yield of the forestry was 79. 16 t /hm2,and the net productivity was 6. 60 t /(hm2·a).
