摘　　要：农业系统是一个开放的复杂大系统。系统的功能决定于系统的结构，合理的农业结构应该是充分合理利用农业自然资源和社会经济资源，因地制宜发挥地区的优势，使农业生态效益与经济效益相结合，构成良性循环，达到低投入，高效益，持续稳定增产的目的。本文根据农业系统的开放性、复杂性和层次性，利用系统工程中的结构分解──协调法计算出南宁地区左江流域六县（市）最优的农业结构，即合理的农业结构。为该地区制定经济发展规划提供科学依据。Agriculture system is an open, complicated and great system. Its functions depend on its structure. The rational agricultural structure should make full and rational use of agricultural natural resources and social economic resources; exert regional advantages in the light of local conditions to make good combination of agricultural ecological result and economic benefit. It is to form a good circulation to reach the goal of low investment, good benefical result, and continuing steady increasing in yielding. Based on the opening,complication and gradation of agriculture system, the study makes use of the structural analysis-coordination calculation in systems engineering to work out the best agricultural structure of the six counties or cities in Zuo River Valley of Nanning Area. That is to say, the rational agricultural structure. This will provide scientific basis for making the economic development program in the area.
