摘要

[目的] 构建系统动力学模型，模拟按树生长和用水过程，为种植和管理桉树提供科学支持。[方法] 将桉树生长过程模拟中叶生物量和根生物量的计算和其用水特征联合起来，实现两大框架的耦合。在国内外各选取一个研究区，即澳大利亚的Tumbarumba和广东省的纪家林场，以验证模型的合理性。[结果] 在Tumbarumba站点： ①模型模拟的2001—2014年平均蒸散量为819 mm，实测的年平均蒸散量为867 mm。②胸高直径、林分材积、树高、植株密度4个参数平均模拟精度分别为71%，93%，88%，95%。在纪家站点： ①模型模拟的1999年10月至2000年9月期间蒸散量为1 068 mm，实测蒸散量为1 069 mm。②胸高直径、林分材积、树高、植株密度4个参数平均模拟精度分别为94%，89%，95%，99%。[结论] 系统动态模型模型能够较好地模拟桉树的生长以及用水情况，验证了模型的合理性。该模型仍有改进的空间，可以从提高模型稳定性入手。

Abstract

[Objective] The present study developed a system dynamics model to simulate the growth and water use processes of Eucalyptus in order to provide scientific support for the Eucalyptus plantation and management.[Methods] Two frameworks were coupled together by combining the calculation of leaf and root biomass with the simulation of plant water use. Two areas

the Tumbarumba site in Australia and the Jijia forestry farm in Guangdong Province

were selected to test the performance of the coupled model.[Results] In the Tumbarumba site:① The annual average evapotranspiration from the model simulation during 2001-2014 was 819 mm

while the average annual evapotranspiration from the measurements was 867 mm. ② The simulation accuracy of four parameters of chest height diameter

forest volume

tree height and plant density were 71%

93%

88% and 95%

respectively. In the Jijia forestry farm:① The evapotranspiration from the model simulation from October 1999 to September 2000 was 1 068 mm

while the evapotranspiration was 1 069 mm. ② The simulation accuracy of four parameters of chest height diameter

forest volume

tree height and plant density were:94%

89%

95% and 99%

respectively.[Conclusion] The model can simulate the growth and water use of Eucalyptus

and further improvements especially in the robustness of model are needed.
