<正>通过对简单农林生态系统的能量分析，介绍了对农林生态系统的动态过程及其与生态因子间函数关系进行能量分析的一般方法。并根据能量分析的数学模型进一步进行计算机数值仿真，使抽象的数学分析变为易于接受的图形表达形式；通过生态环境造成的偏差建立控制函数，为生态工程提供了理论分析依据。

This paper briefly introduces the application of energy analysis and its computer simulation in agroforestry ecosystem engineering. By means of energy analysis of the dynamic processes in the agroforestry ecosystems, the relations between these processes and their ecological factors are to be discovered. And also by means of computer simulation, the controlling function is designed in order to offer an object function for the ecological engineering.
