摘要:
目的：通过对扁秆藨草地上部分与地下球茎生长的关系研究，为湿地恢复和白鹤保护工作提供科学依据。方法：在扁秆藨草生长的成熟期，在研究样地内随机选取扁秆藨草，测其地上部分高度，密度及地下球茎干重等。结果：模拟出扁秆藨草地上部分与地下球茎生长的关系。结论：模拟结果和图像显示，扁秆藨草地上部分和地下球茎的增长会出现起伏，这是由于扁秆藨草在不同时期自身的营养流向不同所造成的；模型能够有效的描绘扁秆藨草地上部分与地下球茎生长的动态关系，对扁秆藨草生长的调节提供科学的依据。Objective: The relationship between the growth of aboveground parts (APs) and underground corms (UCs) of Scirpus planiculmis was studied to provide a scientific basis for the wetland restoration and white crane protection work. Method: Scirpus planiculmis was randomly selected at the research plots during their mature stage with the height and density of the APs and the dry weight of the UCs measured. Results: The relationship between the growth of APs and UCs of Scirpus planiculmis was simulated. Conclusion: Results show that the growth of APs and UCs was fluctuated, which is due to the different flow direction of the nutrition in Scirpus planiculmis at different times. More- over, the model can effectively describe the dynamic relation between the growth of APs and UCs and can provide ref- erence for the growth regulation of Scirpus planiculmis.
