摘要
采用灰色关联法分析了影响河北省梨果生产的主要因素。结果表明:关联程度依次为有效灌溉面积>梨果种植面积>成灾面积>耕地面积>农药使用量>农业基本建设投资>农民人均年纯收入>人均地区生产总值>用工量>农用机械总动力>化肥使用量。通过构建两两比较判断矩阵,分析出在11个因素中,有效灌溉面积、种植面积、成灾面积、耕地面积、农药使用量、农业基本建设投资6个因素的影响度总和达到了88.27%,是影响河北省梨果产量的主要因素。
Grey Correla（ion Model was used to analyze the main factors affected pear production in Hebei province. The results showed that,the influences in order were：effective irrigation area〉cultivated are〉inundated area〉agricultural acreageS〉amount of pesticide〉investment of agricultural basic construction〉annual net income per farmer〉GDP per capital〉amount of labor）total power of agricultural machinery〉amount of fertilizer. Pair-wise comparison judgment matrix was adopted to analysis that in the 11 factors,the total influence degree result of effective irrigation area,cultivated area,inundated area,agricultural acreage;amount of pesticide and investment of agricultural basic construction was up to 88. 27% ,the six factors were the main factors influencing pear production in Hebei province.
