【摘要】：水稻种植模式变化会对粮食生产和粮食安全产生威胁。采用比较优势分析法,对湖北省不同水稻种植模式结构与区域分布进行分析,结果表明:(1)湖北省单季稻种植已成为主要种植方式,且各种植模式播种面积基本稳定,双季稻转种单季稻对粮食安全产生一定负面影响,但水稻单产增加弥补了这种效应。(2)湖北省内大部分市域水稻种植模式及结构有所调整,鄂中地区双季稻转单季稻程度最大,目前以单季稻种植为主,鄂东地区调整也较为显著,但双季稻种植仍占很大比重。(3)较全国,湖北省单季稻的规模、效率、综合指数具有稳定比较优势。湖北省内部,各市双季稻种植效率比较优势相对显著,但对综合效率指数影响小,种植规模已成为影响不同模式水稻种植优势的关键。(4)水稻种植模式转变的原因分析显示,不管是内部效益驱动还是农户非农就业外部效益引诱,单季稻种植更吸引农户农业生产。
[Abstract]:The change of rice planting pattern will threaten grain production and food security. The structure and regional distribution of different rice cultivation patterns in Hubei Province are analyzed by comparative advantage analysis. The results showed that the planting of single cropping rice in Hubei Province had become the main planting method, and the sowing area of each planting pattern was basically stable, and the conversion of double cropping rice to single cropping rice had a certain negative effect on food security. However, the increase of rice yield makes up for this effect. (2) the planting pattern and structure of most municipal rice in Hubei Province have been adjusted, and the degree of double cropping rice to single cropping rice is the largest in the middle of Hubei Province. At present, the single cropping rice is the main planting area, and the adjustment in eastern Hubei is also obvious. The scale, efficiency and comprehensive index of single cropping rice in Hubei Province have a stable comparative advantage. The comparative advantage of planting efficiency of double cropping rice in Hubei Province is relatively significant. But the influence of comprehensive efficiency index is small, and planting scale has become the key to the rice planting advantage of different models. The analysis of the reasons for the transformation of rice planting pattern shows that, whether the internal benefit is driven or the external benefit of farmers' non-agricultural employment is induced, Single-cropping rice planting is more attractive to farmers agricultural production.
