我国粮食主产区粮食生产影响因素研究

本文分析了我国粮食主产区在我国粮食生产中的重要地位,并通过灰色关联分析法研究了影响粮食产量的相关因素的灰色关联系数,由大到小依次为,粮食播种面积>有效灌溉面积>粮食单产>复种指数>农机总动力>旱涝保收面积>机播面积>机耕面积>农村用电量>机电排灌面积>化肥用量>成灾面积;在此基础上,重点研究了耕地、水资源状况、有效灌溉面积、农业现代化水平及农业科技进步对粮食生产的影响作用。

Effect Factors on Grain Product in Main Grain Product Areas of China

The important effect of main grain product area in China on grain product has been studied in the thesis.The grey relationship coefficients to grain product has been study in grey relationship analytical method.The sequence of grey relationship coefficients from great to little is as commissariat sowing area greater than available irrigation area than commissariat product per area than replanting index than agriculture machine total impetus than drought and water logging keep harvesting area than machine sowing area than machine furrow area than country electrical using dosage than machine electrical irrigation and drainage area than fertilizer dosages than resulted disaster area.The effect of plantation area and water source status and available irrigation area and agricultural modernization level and agricultural science and technology progress had been studied.
