基于灰色预测法对安徽省农业循环经济发展的研究

A Study on the Development of Agricultural Circular Economy in Anhui Province Based on Grey Forecasting Method

针对安徽省农业循环经济的发展,使用了回归分析、模糊层次分析、灰色预测等方法,分别建立了耕地质量综合评价、灰色预测模型,综合使用EXCEL和MATLAB软件对耕地质量分级、基础地力预测和2020年安徽省灌溉水系数进行分析与预测。促进安徽省农业循环发展,应采取措施提高较差等级土地的耕地质量和灌区灌溉水的利用系数。

Directing at the development of agricultural circular economy in Anhui Province,the methods of regression analysis,fuzzy hierarchy analysis and grey forecasting method are adopted,and the comprehensive evaluation of arable land quality and the grey forecasting model are established.Excel and MATLAB softwareare integrated to classify the quality of arable land,predict the basic soil productivity and analyze and predict the irrigation water coefficient in Anhui Province in 2020.To promote the circular development of agriculture in Anhui Province,measures should be taken to improve the quality of arable land in poor grades and the utilization factor of irrigation water in irrigated land.
