基于灰色关联分析模型的河南粮食产量影响因素分析

Analysis of Factors Affecting Henan Grain Yield Based on Grey Correlation Analysis Model

为在粮食生产中科学分配资源,提高粮食产量,选取2000年-2017年的河南省统计年鉴统计数据,选用灰色关联分析模型对影响河南省粮食产量的8个因子进行建模分析。结果表明:农药施用实物量、化肥施用折纯量和耕地面积是影响粮食产量的重要因素,农村用电量对粮食产量的影响程度最低,灌溉面积、乡村从业人员、农用机械总动力和农用塑料薄膜使用量对粮食产量的影响程度依次降低。

In order to scientifically allocate resources and increase grain yield in grain production, this paper selects the statistical yearbook statistics of Henan Province from2000 to 2017, and selects the gray correlation analysis model to model and analyze the eight factors affecting grain yield in Henan Province. The results show that rural electricity consumption, effective irrigated area and total agricultural machinery power are important factors affecting grain yield. Agricultural production data index has the lowest impact on grain yield, affected area, chemical fertilizer application, grain unit area yield, disaster The extent of the impact on the grain output by the area, the employed persons in the primary industry, and the area planted with food crops decreased in turn.
