本文针对现行作物分类法的局限性，运用农业生态经济系统的功能性原理，提出一种新的作物分类法，以作物生产过程所表现的主体功能为依据将作物分成三大类型即社会型、经济型和生态型，并对每一类型作物的基本特性和增产增效对策进行了系统分析。在此基础上，提出了区域性生态农业建设中农田作物的合理配置的新策略。
Aiming at the limitations of current crop taxonomy and applying the functional principle of agricultural eco-economic system, this paper proposes a new crop classification method, which divides crops into three types based on the main functions of crop production process: social type, Economic type and ecological type, and systematically analyzed the basic characteristics of each type of crops and the measures of increasing yield and increasing efficiency. On this basis, a new strategy for the rational allocation of farmland crops in the construction of regional ecological agriculture is put forward.
