| 摘 要： | 对农业生态经济系统的评价指标稳定性、持续性、均衡性进行了分析,并将三者加权平均作为生产特性指数,乘以多年平均的生产率作为综合生产力,以反映系统的生产力水平及生产特性.对农业生态经济系统的结构特性提出了协调性(多样性)的量化指标,并提出了农业生态经济系统评价指标体系的建议.

| Abstract: | In this paper, the stability, sustainability and harmoniousness of agricultural ecolomicsystem are selected as evaluation indices, and weighted as its productive property inldices.After multiplied by many years average productivity, they can be used to reflect the productivity and productive property of the system. A quantified index of diversity is advanced to describe the structural properties of various agricultural ecolomic systems, and.an evaluation index system of agricultural ecolonlic ystem is put forward. |
