Candidate models considered in model selection and multimodel inference procedures.

Models were compared based on the second-order Akaike information criterion (AICc). K: number of model parameters; w: Akaike weight. Bold characters represent the best model for each response variable. INT: Proportion of intensive crops; FLO: Proportion of flowering crops; LOC: Local floral richness; JJ: Julian day.模型比较基于二阶赤池信息准则（second-order Akaike information criterion, AICc）开展。其中，K为模型参数数量，w为赤池权重。加粗字体代表各响应变量的最优模型。INT表示集约化作物占比，FLO表示开花作物占比，LOC表示本地植物物种丰富度，JJ表示儒略日。
