| 摘 要： | 从中部地区生态果园系统能量流动过程的分室模型出发,提出了对该类系统能量流动过程进行动态模拟的数学模型,并以孟州中部地区生态果园示范工程为实例完成了能量流动过程的模拟计算和实测分析.结果表明,该系统是一个渐进稳定的良性循环系统,输出能量趋于常数,其模拟计算结果与实测值相接近,误差小于0.65%,可直接应用于该类系统能流规律的预测研究.

| Abstract: | From the compartment models of the process of energy flow by ecotypic orchard in mid region of China, mathematical models that simulating dynamically the process of energy flow by this kind of system were built. Applying the example of Meng zhou typical engineering of ecotypic orchard in mid region of China, the simulation calculation and actual analysis of the process of energy flow were finished. The results showed that the system was an asymptotic stable and positive circulating one. The output energy tended to a constant. The results of simulation calculation approached the actual value and error was less than 0.65%, and it could directly be used to forecast and study the rules of energy flow of this kind of system. |
