| 摘 要： | 本文对三道沟乡农业生态系统的现状做了综合调查。经分析认为,该乡牧业生产低而不稳,长期处于混乱状态的根本原因是:系统内部结构不合理以及毁林、毁草、过度垦殖所带来的农业生态环境恶化,明确了该乡农业生态系统各业建设的具体目标。通过线性规划模型的建立,利用电子讨算机进行系统模拟,做了定量和定性分析,选出了该系统农业生态系统中农牧结构的最优方案,糟出了实现这一方案的关键措施和具体步骤。

| Abstract: | An integrated survey of the agroecosystem of sandaogo village conducted. Farm Production in this village had suffered from long term instability and low levels of production The survey revealed that this situation was a result of inefficient use resources, poorintegreation of the various components in the system and degradation of thland due to soil erosion caused by deforestation, destruction of grass land and improper land use In order to make efficient use of resourses we applied the system engineering theory to devise some concrete goals for restructuring the agroecosystem. Linear programming was used to simulate a model of the agroecosystem. Through quantative and qualitativc andysis we developed some Key steps for making opimal use of resources. |
