摘　　要：采用非期望产出的SBM模型测算河北省粮食作物系统的生态效率,并运用Tobit模型分析影响因素。结果显示:研究期内河北省粮食作物系统平均生态效率由2011年的0.659增长至2020年的0.837,在空间分布上呈现由从南向北递减转变为从南北向中间递减的新格局;粮食生态效率的主要影响因素为化肥使用强度、粮食作物种植结构、农村居民人均可支配收入和有效灌溉率。为进一步促进河北省粮食生产的绿色发展,建议粮食生产中控制农业化学品的使用范围、种类与规模,重视种植结构的前期规划,改善灌溉方式。Using the SBM(Undesirable Output)model,we assessed the ecological efficiency of the grain crop system in Hebei province and applied the Tobit model to analyze influencing factors.The results are as follows:During the study period,the average ecological efficiency in Hebei province increased from 0.659 in 2011 to 0.837 in 2020,with a shift in spatial distribution from decreasing from south to north to decreasing from both the south and north towards the central regions.The primary influencing factors of grain ecological efficiency are fertilizer usage intensity,crop planting structure,per capita disposable income of rural residents,and effective irrigation rates.To further promote the green development of grain production in Hebei province,it is recommended to control the scope,types,and scale of agricultural chemical usage within grain production,emphasize early planning of crop planting structure,and improve irrigation methods.
