摘要

该文提出了确定区域粮食产量发展目标的“生产单元长时段产量动态分析法”

并根据黄土高原国家试验示范区粮食产量长期动态资料，提出渭北粮食近期8亿kg增产潜力。旱作粮食单产指标达到4050kg/hm

其中小麦为3750kg/hm

玉米为6750kg/hm

并指出实现指标的3项措施。对于陕北地区，根据其农业生态环境条件，明确指出，在农业发展上不宜提建设“粮仓”目标，应定位在生态农业建设上，做到粮食自给有余。

Abstract

Based on the data of long term development in cereal production of national experimental demonstrative site in the loess plateau

the author suggests that cereal yield of 800 millions kilogram could be increased in Weibei area of Shaanxi province.The yield of unit area can reach 3750kg/hm2 for wheat

6750kg/hm2 for corn and 4050kg/hm2 for cereal.And three approaches for increasing yield are suggested.The author points out clearly that barn target is not appropriate for Shaanbei area.The appropriate target should be eco-agriculture construction and more than selfsufficient for cereal production in this area based on the agricultural ecoenvironment condition.
