Discussion on development of crop models | 作物模型发展探讨

Chinese. 为进一步深化与促进作物模型发展，并融入国际潮流，论文以系统学思想为指导，采用系统分析、分类、比较及认识论挖掘等方法，通过作物模型概念、分类、作用及其与数字种植业的关系分析，阐述了作物模型的作用，综述了国内外作物模型研究与应用新动态，比较了国际上作物生长模型四大研究组（DSSAT，School of de Wit，APSRU及中国）和功能-结构植物模型三大研究组（L-Studio，GREENLAB及中国）间作物模型的差异，分析了存在问题，提出了进一步发展的对策和建议。目前，虽然作物模型在数字种植业中的应用较少，但随着中国农业的发展，特别是城乡结构的变化，未来它将具有广阔的应用和发展前景。

English. In order to deepen the studies of crop models (CMs), promote its development, and make it to join into international development tide, the methods of systematic analysis, classification, comparison, and mining of epistemology, etc were adopted in this paper. The roles in CMs were set forth through definition and classification of CMs, and the relationships between CMs and digital plant (DP) were analyzed in this paper. The latest studies and application progresses of CMs in China and overseas were reviewed, the issues in their current studies and application were analyzed through comparison of differences in plant growth models among four research groups (DSSAT, School of de Wit, APSIM, and China) and in functional structural plant models (FSPMs) among three research groups (L-Studio, GREENLAB, and China) in the world, and some countermeasures and suggestions for their further development were proposed. At present, although the application of CMs and DP is little, it will have a wide development and application foreground with development of agriculture in China in future, especially, changes in proportion of town and countryside.
