亚热带珍稀植物福建含笑群落能量研究

STUDY ON ENERGY OF MICHELIA FUJIANENSIS COMMUNITY IN SUBTROPICAL ZONE

  • 摘要: 对福建含笑(Michelia fujianensis )群落各组分的热值、群落能量现存量、能量年净固定量和太阳能转化效率的研究结果表明:该群落各组分样品的干重热值具有一定差异, 树干热值最高, 花热值最低。福建含笑群落的能量现存量859.93×1010J/hm2, 其中地上部分723.67×1010J/hm2, 占总量的84.15%;地下部分136.26×1010J/hm2, 占15.85%。福建含笑1997年群落能量净固定量为32.72×1010J/hm2, 林地太阳光有效辐射能转化效率1.536%。

     

    Abstract: Based on the measurement of biomass and the rate of its increase, caloric values of respective plant organs, total energy of standing crop, annual net energy conversion and its efficiency in Michelia fujianensis community was determined.The results showed that some disparities of gross caloric value existed among plants organs in the community, e.g.the bark had the highest and the flowers the lowest.The total energy of standing crop in the community was 859.93×1010J/hm2, of which 723.67×1010J/hm2 (84.15%), was abovegound and 136254×1010J/hm2 (15.85%), underground.In1997 net energy fixation was 32.72× 1010J/hm2 and energy conversion efficiency of photosynthetic active radiation was 1536% for the community.
