我国农田水利建设对粮食生产的减灾增量效果及作用机制研究
Disaster Reduction and Growth Effects and Machanism of Farmland Water Conservancy Construction on Food Production in China
摘要
Abstract
Farmland water conservancy construction has an irreplaceable role in enhancing agricultural disas-ter resilience and promoting increased grain production.By utilizing 31 inter-provincial panel data in China from 2000 to 2021,the disaster mitigation mechanism of farmland water conservancy construction on grain production is empirically tested by using a fixed-effects model.The results show that farmland water conservancy construction stimulates grain production through the path of reducing the area affected by floods and droughts,and for every 1％increase in the effective irrigated area and flood-removing area,the grain-affected area will be reduced by 31.3％and 7.4％,respectively,and the reduction in the affected area will safeguard the grain production,which will lead to the increase in grain production by 23.8％and 2.4％by farmland water conservancy construc-tion.In terms of heterogeneity,the effect of farmland water conservancy construction on grain production in North China is optimal in terms of disaster prevention and mitigation.Accordingly,it is recommended that the construc-tion of high-standard farmland be completed as soon as possible to implement the requirements for disaster preven-tion and mitigation,to ensure a sustained and stable supply of grain,and to maintain food security in China.关键词
