摘要
以安徽省为例,针对农业循环经济发展过程中的耕地质量等级评价问题,建立了模糊综合评价模型.将安徽省土地质量划分为7个等级,并预测出到2020年基础地力将普遍提高,土壤有机质含量预测在2020年时,处于中等水平的有效磷相对于2012年增加至少7个百分点,处于中等水平的速效钾会增加3个百分点.根据结论分析,提出促进安徽省农业循环经济发展的意见.
Takes the example of Anhui Province, establishes a fuzzy comprehensive evaluation model in terms of the development of agricultural recycling economy. The land quality is divided into seven grades, and predicts that the basic soil will generally increase soil organic matter content in 2020, the moderately effective amount of available phosphorus wiU increase by at least 7 percentage points relative to 2012, and the moderately potable potassium will increase by 3 percentage points. According to the conclusion of the analysis, puts forward the suggestion of promoting the development of agricultural circular economy in Anhui Province.
