Abstract: To advance research on digital crop system simulation, the industrialized idea of the integrated manufacturing was introduced into the case of crop modeling, the concept of Crop Model Resource (CMR) and Crop Model Resource Construction Platform (CMRCP) were proposed in this paper. The crop model resource includes general model structure, modeling algorithm expression and model resource mapping. The all-around model representation method of crop model resource was proposed that combines model and/or concept tree, model and /or algorithm graphics with pattern of implementation. Based on component framework, component assembly and model compiling techniques, the principle of CMRCP was established according to adaptive software development. The platform works with crop metamodel, learning mechanism, model construction engine and support tools for modeling. The results show that constructing the CMRCP with ability of learning, adaptability and component characteristics, can advance the crop modeling knowledge resources and the crop model development resources changes, can enhance the crop model resource library for sharing and reuse. It helps to make it easy to conduct crop model construction and development, which improves the quality and efficiency of software development, and provides construction platform for crop intelligence modeling.
