TableS7_util_foreign_overtime_FS_1961-2009

Table S7. Change in use of foreign crops in national food supplies, from years 1961-2009. Data includes minimum and maximum use values for each variable for each country in each year, as well as slopes of change and variation metrics over the time period as estimated in a Bayesian framework using an interval-censored response variable bounded between minimum and maximum use estimates. Year was centered at 1985 for modeling purposes, thus model intercepts represent mean use in this year.补充表S7：1961年至2009年各国粮食供应中外来作物使用量的变化情况。本数据集包含各年份、各国各变量对应的最低与最高使用量取值，同时涵盖基于贝叶斯框架（Bayesian framework）、以最低与最高使用量估算值为边界的区间删失响应变量（interval-censored response variable）所估计的时段内变化斜率与变异度指标。为满足建模需求，研究将年份以1985年为基准进行中心化处理，因此模型截距（model intercepts）代表该年份的平均使用量。
