在生物量、生产力研究基础上，对武夷山甜槠（Ｃａｓｔａｎｏｐｓｉｓ ｅｙｒｅｉ（Ｃｈａｍ ｐ．ｅｘ Ｂｅｎｔｈ．） Ｔｕｔｃｈ．）群落各组分的热值、群落能量现存量、能量年净固定量以及太阳能转化效率进行了研究。结果表明：（１）甜槠群落各组分样品的干重热值具有一定的差异，树皮热值最高，细根热值最低。（２）甜槠群落的能量现存量达７８０５８４．１ ｋＪ·ｍ － ２，其中地上部分为６７８９１３．８ ｋＪ·ｍ － ２，占总量的８６．９８％ ；地下部分为１０１６７０．３ ｋＪ·ｍ － ２，占１３．０２％ 。（３）甜槠群落的能量年净固定量（１９９２年）为２６８５６．２ ｋＪ·ｍ － ２·ａ－ １，林地太阳光合有效辐射能的转化效率为１．２９６％ 。
Based on the studies of biomass and productivity, the calorific value of each component of Castanopsis eyrei (Cham p.ex Benth.) Tutch. Community, the stock of community energy, the net fixed annual energy, and the solar energy conversion efficiency Study. The results showed that: (1) The caloric value of dry weight of each component of sweet-tempele community has some differences, the bark caloric value is the highest, the fine root caloric value is the lowest. (2) The existing energy of Populus davidiana community is 780584.1 kJ · m - 2, of which the aboveground part is 678913.8 kJ · m - 2, accounting for 86.98% of the total; the underground part is 101670.3 kJ · m - 2, accounting for 13.02%. (3) The energy annual net fixed mass (kg) of the sweet riparian community is 26856.2 kJ · m -2 · a -1, and the conversion efficiency of photosynthetically active solar radiation is 1.296%.
