摘要
在“双碳”目标的背景下,提高吉林省延边州粮食种植生态效率对于缓解边疆少数民族地区经济与环境压力、推动地区农业高质量发展具有重要意义。该研究采用非期望产出SBM模型,测试延边州8个县市的粮食种植生态效率,并深入分析其时序演化特征、区域差异和空间格局。其结果表明:2010-2021年,延边州粮食种植生态效率总体有所提升,但增长不稳定;延边州东部和中部地区粮食种植生态效率相对较高,而西部和北部地区则较低,空间格局上呈现出明显的地域集聚现象,形成了高效生态农业区与低效生态农业区。基于分析结果,该文从制定差异化区域发展策略,加强环境管理与政策制定,深化科技进步,提升公众环保意识等几个方面提出相应对策,以期为提升延边州乃至全国粮食种植生态效率提供参考。
Under the"dual carbon"goals,improving the ecological efficiency of grain planting in Yanbian Prefecture,Jilin Province,is crucial for alleviating economic and environmental pressures in border minority regions and promoting high-quality agricultural development in the area.Using an SBM(slack-based)model that includes undesirable outputs,the ecological efficiency of grain planting in the eight counties and cities of Yanbian Prefecture was measured,and its temporal evolution characteristics,regional differences,and spatial patterns were analyzed in depth.The research results show that from 2010 to 2021,the overall ecological efficiency of grain planting has improved,although the growth has been unstable.The ecological efficiency of grain planting in the eastern and central regions of Yanbian Prefecture is relatively high,while it is lower in the western and northern regions,exhibiting a distinct regional clustering pattern where high-efficiency ecological agricultural zones and low-efficiency ecological agricultural zones have formed.Based on the analysis results,corresponding countermeasures are proposed from several aspects,including formulating differentiated regional development strategies,strengthening environmental management and policy formulation,deepening technological progress,and enhancing public environmental awareness,with the aim of providing a reference for improving the ecological efficiency of grain planting in Yanbian Prefecture and nationwide.
