福建中亚热带农业生态类型的成因与发展机制──Ⅰ．农业生态经济系统的宏观分析

Contributing Factors and Developmental Mechanisms of Agroecological Types in the Mid-subtropical Region of Fujian Province Ⅰ.An Analysis on the Agroecological Systems From Macro-viewpoints

以人均收入为线索，分析了福建中亚热带农业生态经济系统的现状，从中归纳出城郊“贸工农”型、产业开发型、资源利用型和传统农业型等４种农业生态类型．运用横向比较和纵向分析方法，研究４０多年来全区农业生态经济系统的发展过程．阐明了不同发展阶段的生态经济特征及存在问题，为进一步研究中亚热带地区农业生态类型的成因与发展机制提供背景材料．

This paper deseribed the pregent situation of the agroecological systems in the mid-subtropical region of Fujian Province by analysing their agroecological characters. Based on their agroecological conditions, the developmental process of the agroccological systems were examined. In turn four types of agroecological systems and five developmental periods characterized by diffcrent historical backgrounds and agroccological condititions were determined and discussed. The result could be taken as an important reference to make further investigations on it.
