结果表明：植物各器官的干质量热值、去灰分热值分别在10.7～22.17和13.89～23.04kJ·g-1之间，叶片的干质量热值和去灰分热值明显高于其他器官(P.05)。

Different parts of twenty dominant plant species in five plantation communities on the subtropical hilly lands in Heshan of Gunagdong as well as the litters from three of the five plantation communities were sampled, and their gross caloric value and ash content were measured by using a PARR-1281 oxygen bomb calorimeter and a muffle furnace.

从广东鹤山南亚热带丘陵5种人工林群落中采集20种主要植物器官及3种群落凋落叶样品，利用PARR-1281氧弹热量计和马福炉分别测定样品的干质量热值和灰分含量，再计算去灰分热值；按器官、个体和生长型等比较分析植物的热值和灰分特征。

The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.

结果表明：各物种的热值动态变化规律并不是统一的，这种变化可能与植物各器官热值的变化及生殖期出现的时间有关；各植物器官的热值普遍表现出穗的热值大于茎和叶；水生植物的热值明显小于中生性和湿中生性植物；种内热值变化随物候期变化有一定的规律，大约会出现2次低值、2次高值；种间热值差异是由于植物本身性质决定的，在相同生境和气候条件下，植物体中含能物质越多，就越易积聚热值，从而更适宜生长在此环境。
