摘要
通过建立广西北部湾经济区农业总产值母函数与农用机械总动力、化肥使用量、有效灌溉面积和农作物总播种面积子函数之间的灰色斜率关联分析模型,取2005—2011年间各指标数据,分析母函数与各子函数之间的灰色斜率关联度,揭示各子函数对母函数的影响程度。结果表明:4个子函数因子中,农用机械总动力对地区农业总产值影响最大,表明良好的机械耕作条件和基础设施有利于提高农业产值。
Grey slope incidence analysis model was established between generating function for gross output value of farming and subfunctions for total agricultural machinery power, consumption of chemical fertilizers, irrigated area and total sown area of farm. Grey slope incidence degrees were calculated between generating function and subfunetions based on the data from 2005 to 2011. And the extent of subfunctions impact on generationg function was also revealed. The result showed that total agricultural machinery power had maximum impact on regional gross output value of farming. So good mechanical farming conditions and infrastructure are helpful to improve gross output value of farming.
