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。

With methods of limited areas, root systems of plant individuals were limited in a specific range, providing definite spatial boundary and solid basis for calculation of water requirement needed by plant individuals. On the basis of calculation of amount of water requirement, areas needed by every species to ensure enough water requirement are as follows: Populus simonii is 80.3m〓, Ulmus macrocarpa is 35. 4m〓, Artemisia halodendron is 7. 0m〓, Salix gordejvii is 11. 2m〓. Prunus armeniaca is 15. 2m〓, and Caragana microphylla is 15. 6m〓. The corresponding rational density of plantation which can maintain soil water balance and can ensure plantation stability is 125 individuals/ha for Populus simonii, 285 individuals/ha for Ulmus macrocarpa, 625 individuals/ha for Prunus armeniaca, 625 individuals/ha for Caragana microphylla, 833 individuals/ha for Salix gordejvii, and 1428 individuals/ha for Artemisia halodendron, respectively.
