20世纪50年代以后，中国玉米主产区进入了较快的演变与发展时期，并表现出一系列特点。玉米主产区的演变与发展是社会需求、科技进步和比较收益变化等多重因素影响的结果。近年来玉米主产区面临着优良品种支撑力不足、经营规模狭小、水资源约束、流通体系不相适应、缺少发展战略设计等问题。从玉米主产区的发展趋势看，种植面积扩大的空间越来越小；内涵发展是主产区发展的根本出路；玉米内部种植结构将进一步调整优化；核心产区将建成中国的玉米产业基地。

The development and evolution of the major maize producing areas had great changes in China from the 1950’s, which has shown a series of characteristics. The evolution of the major maize producing areas is the result that multiple factors such as social demand, technology progress, comparative effectiveness. Recently stage existing main problems is insufficient on the technological support of fine varieties, the constraint of the management scale of land and water resource, the inadaptable issue of the circulation system, and absence of design of maize development strategy and so on. The development trends of the major maize producing areas development and evolution is that the space of expanding cultivated areas is more and more small; intensive management is the fundamental choice for the development of the major maize producing areas in China; cropping structure will further be Optimized; the core region will be build Chinese maize industrialized base.
