2004-2012年河南省农作物生产结构合理性评价

针对农作物生产结构中粮经作物之间竞争日益激烈等问题，以河南省为研究区域，从省－地级市的尺度，根据2004—2012年的农作物产值与物耗费用等数据，利用洛伦兹曲线模型、灰色关联度分析模型并结合投入产出系数，以经济效益为标准分析并评价了河南农作物生产结构的合理化程度。结果表明：2004—2012年河南省整体和各地级市的农作物生产结构合理化程度呈上升趋势；2005年之后河南省整体的经济作物的合理化程度高于粮食作物，而各地级市是在2008年之后经济作物合理化程度逐渐高于粮食作物；经济作物与河南整体农作物生产结构的合理性程度变化趋势相似；河南省合理化程度分布呈十字结构，合理化程度高的地级市分布在南北方，较低的地级市横穿东西向。对此，提出了推动河南农作物生产结构合理化进程的对策建议。

Evaluation on the Rationality of Crop Production Structure in Henan Province during 2004-2012

According to the issues of crop production structure by competition of grains and cash crops ,taking Henan Province as the research area,from the scale of province-city,choosing the data of crop output and material from 2004 to 2012,using the Lorenz curve model, grey rela-tional analysis model combined with the input-output coefficient,taking economic benefits as the standard, the reasonable degree of crop pro-duction structure in Henan was analyzed and evaluated.The results showed that the reasonable degree of the crop production structure of Henan and all the cities is on the rise;The rational degree of economic crops in Henan Province is higher than that of grain crops after 2005, and the economic crops rationalization degree is higher than that of grain crops after 2008 in every city;The trend of the rationality of the eco-nomic crops and the whole crop production structure in Henan is similar; The rational degree distribution of Henan Province is in the cross structure,the city with a high degree of rationalization is distributed in the south and the north, the low is across the east low.The correspond-ing suggestions to promote the process of rationalization of crop production structure in Henan were proposed.
