福建中亚热带农业生态类型的成因与发展机制──Ⅱ．村级农业生态经济类型分析

Contributing Factors and Developmental Mechanisms of Agroecological Types in the Mid-subtropical Region of Fujian Province ──Ⅱ.An Analysis on Rural Agroecological Types

运用聚类分析及农业系统熵等方法，分析了福建中亚热带农村农业生态系统的状态特征，得到１１种不同类型的系统结构．按人均资源占有量将１１种类型归纳为资源短缺型、资源贫乏型、资源约束型、资源适中型、资源偏富型和资源丰富型６大类．主要分布在城郊、远郊和山区地带，构成了以城市为中心呈辐射状排列的生产格局，反映了全区发展的不平衡性．３种地理分布型对应３种经济循环形式，即城郊型的以商品性生产为主的外向型循环、远郊型的以商品性生产和自给性生产并存的二元循环以及以自给生产为主的内向型循环，体现了３个不同的生产阶段即商品生产阶段。

In this paper, village was taken as the basic unit, and system approaches including cluster analysis, agrosystem entropy, etc.,were used to classify and analyse the agroecological types in this region. The reregion. These types could be divided into six systems with different agricultural resources,i. e.,short, poor,limited,moderate, rich,and richer types.All of them were distributed over suburban, distant suburban and mountainous areas respectively. The productivities and the intensive extent could be expressed as concentric and the developmental levels of various systems were related to the share of resourcses and the distribution of geography. Suburban agriculture was characterized by "planting-processing-trading", mountainous type has the character of "planting-breeding-processing", while distant suburban type possesses both of the properties. These three agroecological types represent three developmental stages, i. e., commodity production,semicommodity production and self-sufficient production stages.
