Since 1996,some tropical and subtropical tree species were introduced to Tongan district,Xiamen city,and 133 tree species were totally fixed planting.And since 1972,thirty six tree species among them including Michelia macclurei,Manglietia glauca,Homalium hainanensis,etc.had been planted for pilotscale experiment.The result showed that five tree species(Michelia macclurei,Homalium hainanensis,Duabanga grandiflora,Albizzia faleata,and Mytilaria laosensis)were suitable for planting widely as timber plantation in mountain area at south of Fujian province.

本文对建瓯市毛竹丰产林的能量结构进行了研究，结果表明，１９９５年建瓯市毛竹丰产林地上部分能量现存量为１１９７７４．８ＫＪ／ｍ２，其中竹叶为７２４９．２ＫＪ／ｍ２（占６．０％），竹枝为１７４１４．１ＫＪ／ｍ２（占１４．５％），竹秆为９３９６９．１ＫＪ／ｍ２（占７８．５％），林下植物为１１５１．４ＫＪ／ｍ２（占１．０％）；地下部分能量现存量为４１８１９．３ＫＪ／ｍ２．毛竹标准样竹的样品中，枝、叶、秆的干重热值分别为１９８７３Ｊ／ｇ、１９４４２Ｊ／ｇ和２００８１Ｊ／ｇ．毛竹林群落地上部分和地下部分能量在垂直分布的配置上分别呈“金字塔型”和“倒金字塔型”的能量结构
