基于AHP与模糊综合评价的土壤有机质提升项目效益评价

AHP-based Fuzzy Benefit Evaluating for the Project of Improving Soil Organic Matter

本文以四川省土壤有机质提升项目为例,充分收集项目示范区基础资料,以相关研究理论为指导,构建了一个由14个指标组成的效益评价指标体系,从经济效益、社会效益、生态效益三个方面进行效益评价。运用层次分析法确定各指标的权重,以多层次模糊综合评价法构架评价模型,对示范区土壤有机质提升项目进行评价研究。本文对规范和指导提升土壤有机质的实践活动,衡量土壤有机质提升项目的效益效果,实现土壤有机质提升的科学决策有指导意义。

Based on the project of improving soil organic matter in sichuan province,adequately collecting the information of the project and studying the related theory,the article constructed the benefit evaluation system including 14 indicators,which consists three aspects of the economic benefit,social benefit and ecological benefit. Then,the article used analytic hierarchy process( ahp) to determine the weight of each indicators and built the multi- level fuzzy comprehensive evaluation method,to evaluate the project of soil organic matter. It is important for guiding practical activity of improving soil organic matter,measuring the benefit of the project and making the scientific decision of improving soil organic matter.
