摘 要 ：利用问卷调查方法，对江西省余江县121个农户进行逐户调查。根据农业可持续发展原理，采用主成分分析法和综合评价法对纯粮、农牧林、农牧果、农牧加、农牧蔬、农果、农牧药材和农牧等8种生态农业模式的可持续指数进行分析。结果表明，8种生态农业模式可持续指数在0.200 0～0.596 2 间；其中以纯粮模式可持续指数最小，农牧加模式可持续指数最大。纯粮农业模式可持续性指数为0.200 0；农牧药材、农牧、农果、农牧蔬和农牧林等模式可持续性指数处于0.31～0.47之间；农牧加和农牧果模式可持续性指数分别为0.596 2和0.513 3。为促进生态农业可持续性增长，必须拉长生态链条，增加农业生态系统组成，强化生态农业的稳定性。

Abstract:121 households in Yujiang County, Jiangxi Province were interviewed using pre-designed questionnaire. Based on initial data analysis, the region can be classified into 8 eco-agricultural patterns: pure food grain（P₁）,agro-silvo-pasture（P₂）, agro-fruit-pasture（P₃）, agro-pastoral-processing（P_{4）, agro-pastoral-vegetable（P5）, agro-fruit（P6）, agro-pastoral-medicine（P7） and agro-pasture（P8）. The method of principal component analysis and integrative evaluation were adopted. The 8 eco-agricultural patterns were evaluated and analyzed in accordance with sustainable agricultural development. The sustainability index of the 8 eco-agricultural patterns ranges from 0.200 0~ 0.596 2, with P1 having lowest（0.200 0）. The sustainability indexes for P2, P5, P6, P7, P8 are between 0.31 and 0.47, and those for P4 and P3 are 0.596 2 and 0.513 3 respectively. A prolonged ecological chain can augment eco-agricultural sustainability index, improve eco-agricultural systems and enhance eco-agricultural stability.}
