| 摘 要： | 本文主要研究我国东南沿海红树植物叶的灰分含量和热值含量的变化。在海南琼山沿海不同种红树植物之间，随叶灰分含量增加(7.11—9.8%)而干重热值减少(20.62—18.87kJ／g)，但去灰分热值变化不大，在21.5kJ／g左右。同一种秋茄植物，在纬度较低(低于24?N)的地区，叶灰分含量较低，干重热值较高；在纬度较高时(高于24?N)则相反。秋茄幼树(1—7龄间)随年龄增长灰分含量下降，干重热值提高，而去灰分热值变化不大。热值季节变化中，夏秋较高，冬春较低。

| Abstract: | The paper deals with the changes of caloric value and ash content of the leaves in some mangrove species of China. The results were determined as follows. 1. In the area of Qiongshan in Hainan, the gross caloric value (20.62 to 18.97 kJ/g) decreased with the increase of ash content among different mangrove species. The ash-free caloric value of all species, however, was close to 21.5 kJ/g, with little variation. 2. For the same species, Kandelia candel, the ash contents were lower, and the gross caloric value were the higher in lower latitudes (less than 24?N). The opposite is true for higher latitudes (more than 24?N). 3. For K. candel ash content decreases and the caloric value increases as the tree grows. But the ash-free caloric value changes much less. 4. Seasonly changes of Caloric values (GCV and AFCV) of Kandelia leaves in Longhai of Fujian showed that in summer and fall was higher than that in winter and spring. |
