基于地理探测器的河北省粮食产量影响因素研究

Studies on Influencing Factors of Grain Yield in Hebei Province Based on Geographical Detector

以河北省11个地级市的粮食产量作为研究对象,选取14个与粮食产量关系最密切的影响因子,利用地理探测器的因子探测和交互作用探测分析方法,对不同因子对粮食产量的影响进行分析,得出河北省11个地级市粮食产量的空间分异格局以及不同种类粮食产量的主要影响因素。结果显示:农作物总播种面积、耕地面积、农业机械化水平、农业技术人员、化肥施用量是粮食产量的显著影响因子。耕地面积、农作物播种面积和农林牧渔从业人员交互影响作用最强。农业机械使用中联合收割机的使用极大地影响了河北省粮食总产量。

Taking the grain yield of 11 prefecture level cities in Hebei Province as the research object,this paper selects 14 factors which are most closely related to the grain yield,and analyzes the influence of different factors on the grain yield by using the factor detection and interaction detection analysis method of geographical detector.The spatial distribution pattern of grain yield and the main influencing factors of different kinds of grain yield in prefecture level cities were analyzed.The results showed that:the total sown area of crops,cultivated land area,agricultural mechanization level,agricultural technicians,fertilizer application amount were the significant factors affecting grain yield.The interaction among cultivated land area,crop planting area and agricultural,forestry,animal husbandry and fishery practitioners was the strongest.In the use of agricultural machinery,the use of combine has greatly affected the total grain output of Hebei Province.
