基于层次分析法的纸坊沟流域农业生态经济系统效益评价

通过对农业生态经济系统效益进行量化，判断区域农业生态经济效益的发展趋势，为优化产业结构提供依据。以纸坊沟流域为例，对2001-2008年农业经济调查数据进行分析，运用层次分析法对农业生态经济系统效益评价体系进行分析，通过专家咨询法确定关键指标及其权重，结合相关评价标准及打分法（10分制）对数据进行标准化，利用权重及标准化值对数据进行归一化处理，得出农业生态经济系统效益评价的量化结果。结果表明:2001年、2005年和2008年纸坊沟流域农业生态经济系统效益综合分值分别为5.409、6.153和7.026，分别为“中等”和“良好”级。层次分析法可进行定量-定性转换，更加直观地表达流域农业生态经济系统效益变化趋势。
