| 摘 要： | 对广东深圳福田红树林自然保护区的7种红树植物叶热值和灰分含量的季节变化进行了研究.结果表明:(1)7种红树植物叶的灰分含量存在差异,且具有一定的季节变化;(2)7种红树植物叶中,大戟科的海漆、梧桐科的银叶树这两种红树植物叶的干重热值与灰分含量具有极显著的线性相关,其余5种红树植物叶的干重热值与灰分含量相关性不显著;(3)从干重热值的季节变化来看,2001年1月(冬季)、2001年4月(春季)7种红树植物叶的干重热值与灰分含量有极显著的线性相关,2000年7月(夏季)7种红树植物叶的干重热值与灰分含量有显著的线性相关,2000年10月(秋季)7种红树植物叶的干重热值与灰分含量相关性不显著;(4)7种红树植物叶的去灰分热值与干重热值存在不同的季节变化趋势,但7种红树植物叶的去灰分热值均是秋季最高.

| Abstract: | Seasonal changes in the caloric values and ash contents of the leaves of seven mangrove species at Futian, Shenzhen are discussed, the result shows as follows: (1)there were differences in ash contents of the leaves of seven mangrove species;(2)gross caloric values( y ) correlate remarkably with ash contents( x )for Excoecaria agallocha leaves and Heritiera littoralis leaves, respectively. There is no significant relation between gross caloric values and ash contents for other mangrove species; (3)for seasonal changes in the gross caloric values, there is extremely significant relation between gross caloric values and ash contents in January and April 2001, significant relation in July 2000, no significant relation in October 2000, respectively; (4)seasonal changes in ash free caloric values are different form those in gross caloric values, but seasonal ash free caloric values in the leaves of seven mangrove species are all the highest in autumn. |
