【摘要】：水稻種植模式變化會對糧食生產(chǎn)和糧食安全產(chǎn)生威脅。采用比較優(yōu)勢分析法,對湖北省不同水稻種植模式結(jié)構(gòu)與區(qū)域分布進行分析,結(jié)果表明:(1)湖北省單季稻種植已成為主要種植方式,且各種植模式播種面積基本穩(wěn)定,雙季稻轉(zhuǎn)種單季稻對糧食安全產(chǎn)生一定負面影響,但水稻單產(chǎn)增加彌補了這種效應。(2)湖北省內(nèi)大部分市域水稻種植模式及結(jié)構(gòu)有所調(diào)整,鄂中地區(qū)雙季稻轉(zhuǎn)單季稻程度最大,目前以單季稻種植為主,鄂東地區(qū)調(diào)整也較為顯著,但雙季稻種植仍占很大比重。(3)較全國,湖北省單季稻的規(guī)模、效率、綜合指數(shù)具有穩(wěn)定比較優(yōu)勢。湖北省內(nèi)部,各市雙季稻種植效率比較優(yōu)勢相對顯著,但對綜合效率指數(shù)影響小,種植規(guī)模已成為影響不同模式水稻種植優(yōu)勢的關(guān)鍵。(4)水稻種植模式轉(zhuǎn)變的原因分析顯示,不管是內(nèi)部效益驅(qū)動還是農(nóng)戶非農(nóng)就業(yè)外部效益引誘,單季稻種植更吸引農(nóng)戶農(nóng)業(yè)生產(chǎn)。
[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.
