【摘要】 采用壕沟法,调查117种植物,分8项因子及序级,将植物根系分布类型分为基本型、深度型及密度型,以生态学规律、理论及体系模式解释其与环境因子之关系。根系分布占据生态位,依生态因子之规律,相互补偿适应,经生态系统稳定后,产生根系分布形态之系统,亦如同植物地上部之发展稳定,而达成生态平衡,此种演变及发展过程可以生态体系模式表示之。更多还原

【Abstract】 With trench method,this study was to survey 117 kinds of plants.According to eight factors and orders,the root distributions of plants were classified to 3 patterns: basic,deep,and dense.The relationships between root distributions and environmental factors could be explained by ecological function,theory,and model.Based on the specific plant’s niche,ecological factors,and mutual compensation acclimation,the system of underground root distribuition would be properly set as the stratification of up-grown part of plants in the ecosystem.This process of development and change is demonstrated in ecosystem physical model.更多还原
