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。
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（P4）,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 ecoagricultural 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.
