摘要

中国最近出台了土地休耕政策,其目的之一在于退耕冬小麦,以恢复华北平原的地下水环境.考虑到华北平原是中国的小麦主产区,这一政策的出台无疑会影响国家小麦的稳定供应.在此背景下,很有必要进行小麦的优化配置,以实现国家粮食生产和水资源保护的"双赢".然而,小麦优化配置的潜在区域在哪里?近年来小麦面积和产量的时空变化分析很有可能对潜在区域的找寻有所裨益.本文即利用农业统计数据揭示了1990–2014年中国县域小麦面积和产量的时空变化特征.在此基础上,结合"自然上可行、经济上合理、社会上可接受"三个原则,最终确定了两个空间连片地区作为小麦优化配置的潜在区域,分别被称为淮河沿线区和东北冷凉区.同时,本文还提出了小麦产量提高的措施及多项农业政策,以促进小麦向上述潜在区域转移.%One of the aims of the recently initiated land fallow policy is to encourage winter wheat abandonment in order to recover the groundwater environment of the North China Plain (NCP); although this also threatens a na-tional secure supply of this crop, as the NCP is the major wheat producing area in China. It is therefore necessary to consider regional wheat reallocation in order to meet the twin chalenges of production and water conservation. An evaluation of spatiotemporal changes in wheat area and production across China in recent years may shed light on the regions that have the potential for realocation; such trends are analyzed in this study using agricultural statis-tical data. Three over-arching principles are proposed that reallocation must be naturaly suitable, economically feasible, and socially acceptable, and together with the result of the spatiotemporal analysis, two continuous areas are recommended as potentialy suitable for wheat realocation—alongside the Huai River and the cold region of northeastern China. We also present strategies to improve wheat yields as well as policies for farmers, aiming to encourage the realocation of wheat to the regions highlighted in this study.
