高标准农田建设对农业气象灾害防御的影响与机制OA

From the perspective of nature-society interaction,this paper constructed a theoretical framework of meteorological environment-land quality-household response-disaster prevention and loss reduction.Then,based on the provincial panel data of China from 2004 to 2022,this paper employed a staggered difference-in-differences(DID)model to analyze the effects and mechanisms of high-standard farmland construction on disaster prevention and mitigation in the context of agricultural meteorological disasters.The results showed that:(1)high-standard farmland construction significantly and sustainably enhanced the resilience of agriculture to meteorological disasters,exhibiting remarkable disaster prevention and mitigation effects.Specifically,the construction of high-standard farmland had reduced the disaster incidence by 12.7 percentage points and crop loss by 16.5%in treatment regions.(2)While these effects were positive across different types of disasters,levels of post-construction management,and agricultural functional areas,the impact was most significant in drought prevention.(3)The disaster prevention and loss reduction effect of high-standard farmland construction was primarily achieved through improving agricultural insurance,disaster monitoring capabilities,agricultural socialized services and the development of facility agriculture.Therefore,in advancing the new round of high-standard farmland construction,it is crucial to adopt a phased and differentiated approach,establish a long-term mechanism that integrates construction,management and maintenance,and guide the shift in its utilization towards modernization and intensification.These measures will provide fundamental support for building a strong agricultural sector.
