| 摘 要： | 根据扩展的全息理论，从人体血液循环功能与农业生态系统循环功能的全息关系出发，确定了影响农业生态系统循环功能的５个基本要素：作物单产，复种指数，饲料的浪费度，畜禽转化率和循环总量，并将人体血液循环的计算公式应用于农业生态系统，建立了描述系统循环过程中动力与阻力相互关系的数学摸型。

| Abstract: | Based on the extended biological holographic theory and on the holographic relationship between the blood circulation in human body and the material circulation in agro ecosystem, the following five factors which affect the circulation function of agro ecosystems were identified: single harvest yield, multiple cropping index, waste extent of fodder, fodder conversion efficiency and circulation quantum. The formula for calculation of arterial pressure in human body has been applied in the study of agro ecosystems. The model for expression of the relationship between motive and resistance factors in the circulation of ago ecosystems has been established. |
