摘要:
基于碳水足迹效率与公平多维视角,结合国家粮食生产功能区和重要农产品生产保护区划定政策、“大豆振兴计划”等政策,构建中国粮食主产区粮食生产空间布局多目标优化模型,采用非支配排序遗传算法III求解分析。结果表明:(1)在保持中国主产区整体年粮食种植总面积不变、粮食总产量不下降以确保粮食安全的基础上,适当调整主产区粮食生产空间布局,可使2020年粮食生产碳排放与用水的效率分别提高3.87%、49.67%,碳排放与用水的不公平性指数分别降低56.00%、14.16%,其中玉米、大豆种植面积在主产区总种植面积中的占比分别上调3.25%、0.75%,水稻、小麦种植面积占比分别下调2.51%、1.49%。(2)主产区粮食生产空间布局具体优化方案为:山东、河南、四川、河北、内蒙古、辽宁、吉林等七省(区、市)增加水稻种植面积,其余六省(区、市)减少,其中山东增幅最大(增加41.59万hm2);四川、内蒙古、辽宁、黑龙江、湖北、江西等六省(区、市)扩大小麦种植面积,吉林、湖南两省不变,其余五省(区、市)减少,其中辽宁增幅较大(增加17.12万hm2);山东、河南、河北、江苏、湖北等五省降低玉米种植面积,其余八省(区、市)增加,江西变动幅度最大(增加30.44万hm2);黑龙江保持大豆生产规模在全国领先,其他省(区、市)增加,其中河北增幅最大(增加18.69万hm2)。继而从国家、省(区、市)两个层面就粮食生产空间布局优化提出对策建议。
Abstract:
A multi-objective optimization model for the spatial layout of grain production in main grain production areas in China is constructed, from a multidimensional perspective of carbon and water footprint efficiency and equity, combined with national policies such as the delineation of national grain production functional areas and important agricultural product production protection areas and the "Soybean Revitalization Plan". The model is solved with the NSGA-III algorithm to analyze the optimization plan. Results show that: (1) while maintaining the total annual grain planting area unchanged and the total grain output not decreased to ensure food security, appropriate adjustments to the spatial layout of grain production in China’s main grain production areas can increase carbon emissions and water use efficiency by 3.87% and 49.67% respectively, and reduce carbon emissions and water use inequality index respectively by 56.00% and 14.16% in 2020. The proportion of corn and soybean planting areas in the total area of main grain production areas have increased by 3.25% and 0.75%, respectively, while the proportion of rice and wheat planting areas have decreased by 2.51% and 1.49%, respectively. (2) The spatial layout optimization of grain production in the main grain production areas is as follows specifically. Shandong, Henan, Sichuan, Hebei, Inner Mongolia, Liaoning and Jilin increase the area of rice cultivation, the remaining six provinces reduce that area, with the largest increase in Shandong (increasing 415.9 thousand hm2); Sichuan, Inner Mongolia, Liaoning, Heilongjiang, Hubei and Jiangxi expand the area of wheat cultivation, Jilin and Hunan keep that area, the other five provinces shrink it, of which Liaoning shows the largest increase of 171.2 thousand hm2; Shandong, Henan, Hebei, Jiangsu and Hubei reduce the corn planting area, the other provinces expand that area, where Jiangxi endows the largest expansion of 304.4 thousand hm2; Heilongjiang maintains the leading soybean production scale, and all the other provinces increase with the largest increase of 186.9 thousand hm2 in Hebei. Then policy recommendations are put forward on optimizing the spatial layout of grain production at both the national and provincial levels.
