毛竹林群落能量结构研究

A Study on the Energy Structure of Phyllostachy pubescens Stand

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”

This paper deels with the energy structure of high yield phyllostachy pubescens stand in Jianou city The results, attained that: the energy content of the above ground parts of the stand in 1995 was 119774 8KJ/m 2, of which leaves, branches, cuims and shrub plants contained 7249 2KJ/m 2(6 0% of the total),17414 1KJ/m 2(14 5%),93969 1KJ/m 2(78 5%) and 1151 4KJ/m 2 (1 0%) respectively; that of the underground parts was 41819 3KJ/m 2; the gross caloric values in branch, leaf and culm were 19873J/g,19442J/g and 20081J/g respectively
