论文研究了农业系统的耦合效应,以达到提高农业资源利用率的目的。基于对农业资源特性的分析,肯定了农业资源开发进行系统耦合的必要性。重点论述了农业系统的涵义,并将其分为6个生产层,表述了每个生产层的特点,这为农业系统耦合提供某些理论基础。设计了农业系统耦合的结构要素,通过各结构要素在时序性、空间格局和生态过程上的相互联系和相互作用,将其结构要素耦合成为一个优势互补的农业系统。这个设计在马坪镇实施,取得显著的耦合效应。由此,讨论了在农业资源开发中如何发挥耦合效应的问题。

For increasing the utilization ratio of agricultural resources,the coupling effects of agricultural system were studied in this paper.Based on the analyses of the characteristics of agricultural resources,the necessities of system coupling for the exploitation of agricultural resources were affirmed.The implications of agricultural system which was divided into six production strata were expounded especially theoretically.The characteristics of each production stratum were described,so as to provide certain theoretical foundation for the study of agricultural system coupling.The structure elements of agricultural system coupling were designed.Through the interrelatedness and interaction between the structure elements in the time sequences,spatial patterns and the ecological processes,the structure elements were coupled in an agricultural system for the mutual complement of superiority.This design was put into practice in mapping town and gained remarkable coupling effects.And how to bring the coupling effects into full play in the process of exploiting agricultural resources was discussed.
