    摘要:

    基于中尺度生态农业建设效益评价指标体系,运用层次分析法确定指标权重,建立了长武县生态农业建设效益评价指标体系。依据长武县1980—2008年间农业生态经济演变过程的资料和研究成果,对长武县29a来的生态农业综合效益进行了评价。结果表明,生态农业效益由1980年的"差"上升到2008年"良";经济效益发展变化最明显;生态效益总体上处于平稳发展期;近几年来,综合效益增长势头明显。为此,需要进一步改善农业生态环境,提高生态效益,使系统整体功能得到增加。

    Abstract:

    Based on the assessment index system of eco-agricultural construction benefit at medium scale,the assessment index system of eco-agricultural construction benefit in Changwu County was established.The weights of indicators were estimated by analytic hierarchy process(AHP).According to the data and research achievements of the evolutionary process of agricultural eco-economic system from 1980 to 2008,the comprehensive benefit of Changwu County was assessed quantitatively.Results showed that the comprehensive benefit of eco-agricultural construction was raised from "inferior" in 1980s to "good" in 2008.Development of economical benefit is most obvious,while ecological benefit develops steadily.The comprehensive benefit has been increased significantly in recent years.In conclusion,the overall function of the agricultural system should be increased by improving agro-ecological environment and ecological benefit.
