基于APSIM模型的可视化小麦生长系统分析

以气象参数、土壤条件和作物属性等基础数据为驱动，通过耦合基于APSIM的小麦（Triticum aestivum）生长模拟模型、形态结构建成模块构建小麦功能－结构模块（Wheat Function Morphostructure Module）。利用计算机图形技术，在.NET平台上，调用OpenGL作图工具，可以绘制小麦器官三维形态，并通过功能－结构反馈校正建立形态建成过程与生理生态过程的内在融合，分析了小麦形态结构随生长过程动态变化的可视化生长系统的研发过程，从而为提高系统开发中预测的准确性和图形对象高仿真度提供关键的技术支持。

Analysis of APSIM-based visual growth system in wheat

Driven by weather, soil, crop variety databases, intergrating APSIM based growth simulation model in wheat and wheat morphostructure module, wheat function morphostructure module was developed. By applying computer visualization technology, a system based visual growth system in wheat is able to be developed and be programmed in the .NET framework. OpenGL library was used for realizing 2D and 3D graphics application and visualization and it could be used for drawing the 3D morphology of organs in wheat. The contact of forming morphostructure and growth was created by a feedback based wheat function morphostructure module, the change process of morphostructure according to growth simulation was analyzed. The forecast accuracy of system will be higher and the level of graphic simulation be better.
