基于熵值法的粮食安全视角下粮食主产区农用化肥问题研究

Research on Agricultural Chemical Fertilizers in Main Grain Producing Areas from the Perspective of Food Security Based on Entropy Method

在粮食安全战略大背景下,粮食的生产安全尤为重要,而作为中国主产粮区的13个省区粮食生产安全问题是粮食安全战略推行过程中所需解决的核心问题之一。粮食生产安全一大指标便是化肥施用量问题。文章通过熵值法对中国粮食主产区的化肥施用量进行赋值及综合得分计算与排名,通过聚类分析得到高施肥量地区、中施肥量地区和低施肥量地区,进而对其产生原因进行了相应分析,最后给出部分改革建议。

In the context of the Food Security Strategy,the production safety of food is especially important,and as a core production safety issue in the 13 provincial districts of China is one of the core issues required for food security strategy.A large indicator of food production is the problem of fertilizer application.This paper assigns a value of fertilizer administration of my country’s food-producing area and performs comprehensive score,and has a high application fertilizer area,a low fertilizer area and a low fertilizer area,and it is generated by cluster analysis.The reason for the corresponding analysis,and finally some reform recommendations are given.
