| 摘要: |
| 在综述国内外生态农业评价研究进展的基础上,从生态农业评价指标体系、评价数学模型和评价原则等方面构建了生态农业评价理论体系;运用层次分析法、专家咨询法和评价指标矩阵确定了评价指标的权重,并以安徽芜湖市为例,对芜湖市郊区、南陵县、芜湖县和繁昌县进行了区域生态系统比较研究。评价结果表明,南陵县和芜湖县的生态环境较好,是发展生态农业较好的区域,繁昌县和芜湖市郊区生态环境较差,污染严重,发展生态农业受到较大限制。研究结果与实际情况比较吻合,说明该评价理论具有一定的应用价值。 |

| Appraising theory on ecological agriculture and its case study |
|
|
| Abstract: |
| On the basis of viewing the research progress of internal and external ecological agriculture,the paper constructs the theoretic evaluation system of ecological agriculture that consists of appraising index system,appraising mathematics model,and appraising principle.The weight of index is defined by Analytic Hierarchy Process (AHP),Delphi and index matrix.And Wuhu city is used as a case study of regional ecological agriculture system that includes Wuhu suburban district,Nanling county,Wuhu county and Fanchuang county.The result is that the environment is good in Nanling county and Wuhu county are suitable for developing ecological agriculture,and the seriously polluted environment in Wuhu suburban district and Fanchuang county restricts the development of ecological agriculture.The research conclusion is close to the real condition,showing that this appraising theory has practical value. |
