摘要: 在夏季对海南东寨港红树林自然保护区一些红树植物木材的灰分含量和热值进行了测定,并研究了夏季不同纬度的秋茄 (Kandelia candel)木材热值的变化.结果表明,红树植物木材的灰分含量较低,在2.43%~5.17%之间;干重热值在17.23~19.21kJ·g-1之间,去灰分热值在 17.70~20.10kJ·g-1之间;嗜热窄布种无瓣海桑 (Sonneratia apetala)木材的干重热值和去灰分热值均是最低;在夏季秋茄木材的热值随纬度升高而下降.

Abstract: The caloric values and ash contents of some mangrove woods in Dongzhai Harbor Mangrove Forest Reserve of Hainan Province were determined in Summer,and the changes of the caloric value of Kandelia candel woods at different latitudes were studied.The ash content of mangrove woods was low,ranging from 2.43% to 5.17%;and their gross and ash-free caloric values ranged from 17.23 kJ·g-1 to 19.21kJ·g-1 and from 17.70kJ·g-1 to 20.10kJ·g-1,respectively. Sonneratia apetala wood had the lowest gross and ash-free caloric values.The caloric value of Kandelia candel wood decreased with increasing latitude in Summer.

Key words: Mangrove species, Wood, Caloric value, Ash content, cucumber, reactive oxygen species, salt-alkaline stress, AsA-GSH cycle, antioxidation
