摘　　要：以曲靖市作为研究区域,采用多元线性回归分析方法,探讨了曲靖市耕地非粮化现状及演变特征,并分析了14个因素对该区耕地非粮化的影响。结果表明,曲靖市耕地非粮化现象较为严重,且呈现出波动增长趋势。其中,生产总值、耕地面积和农用地膜对耕地非粮化具有正向影响,而人均GDP、粮食播种面积、农村劳动力人均耕地面积和总人口对耕地非粮化具有负向影响,城乡居民可支配收入差、农用机械总动力对耕地非粮化起双向作用。基于此,提出了加强耕地保护、提高粮食种植补贴,推进农业现代化等政策建议,以促进曲靖市耕地可持续利用和保障粮食安全。This study took Qujing City as the research area and used multiple linear regression analysis to explore the status and evolution characteristics of non-grain cultivated land.It also analyzed the impact of 14 factors on the non grain cultivated land in the area.The results indicated that the phenomenon of non-grain cultivated land in Qujing City was quite serious and showed a fluctuating growth trend.Among them,output value,cultivated land area,and agricul tural plastic film had a positive impact on the non-grain cultivated land,while per capita gross domestic product(GDP),grain sowing area,cultivated land area per rural laborer,and total population had a negative impact.The disparity in disposable income between urban and rural residents and the total power of agricultural machinery had a two-way effect on the non-grain cultivated land.Based on this,policy suggestions such as strengthening the protection of cultivated land,increasing subsidies for grain cultivation,and promoting agricultural modernization were proposed to facilitate the sustainable utilization of cultivated land in Qujing City and ensure food security.
