| 摘 要： | 研究了鼎湖山南亚热带常绿阔叶林的生物量，发现其中格木（Ｅｒｙｔｈｒｏｐｈｌｅｕｍ ｆｏｒｄｉｉ）群落的生物量为５６８．１７２ｔ／ｈｍ＾２，叶面积指数为２７．８０２５ｍ＾２／ｍ＾２，均高于大面积分布的厚壳桂（Ｃｒｙｐｔｏｃａｒｙａ ｃｈｉｎｅｎｘｓｉｓ）群落。用红外线ＣＯ２气体分析法，分层测定了格木群落主要植物的光合速率和呼吸速度，计算了嫩落的生产力和光能利用率。结果表明，格木群落的总生产力为２７９

| Abstract: | The biomass and leaf area index( LAT )studied in Erythrophleum fordii community in Dinghushan were 568.172t/hm 2 and 27.8025m 2/m 2 and they were higher compared with Cryptocarya chinensis community distributed widely in this region.CO 2 infra red analysis method was used to measure both photosynthesis rate and respiratory rate.The productivity and efficiency of radiation utilization were calculated.The results show that the gross primary productivity was 24970kJ/m 2 ·a,the utilizati... |
