2001-2021年中国化肥施用环境风险及其脱钩研究
Research on Environmental Risks and Decoupling of Fertilizer Application in China from 2001 to 2021
摘要
Abstract
This paper takes the provincial boundary as the unit to calculate the non-point source pollution emissions of fertilizers in each region.ArcGIS software is used to analyze the spatial pattern of fertilizer application amount,fertilizer non-point source pollution emissions,and grain yield.Deviation standardization and environmental risk assessment models are used to evaluate the environmental risks of fertilizer application.The Tapio decoupling model is used to study the coordination relationship between fertilizer application amount and grain yield.Research has shown that the spatial distribution of fertilizer application is gradually dispersing,and grain production is more concentrated in the north-south direction.The hotspots of non-point source pollution emissions are expanding towards the northwest.The relationship between fertilizer application and grain yield has shifted from strong negative decoupling to strong decoupling,and the efficiency of fertilizer use has significantly improved,which is in line with the ideal development trend.This study provides technical and theoretical guidance for the control of fertilizer non-point source pollution and the promotion of fertilization in grain production,which is helpful for achieving sustainable agricultural development.关键词
