中文摘要：

通过分析水稻叶片生长过程中的几何形态数据，构建了水稻叶片几何形态参数与有效积温之间的动态关系模型和水稻叶片空间形态三维模型。结合水稻植株分蘖拓扑结构，利用OpenGL图形接口，在计算机上实现了水稻穗前形态随环境温度动态生长过程的可视化模拟，具有较强的真实感，为构建虚拟水稻生长系统奠定了基础。

英文摘要：

By＇analyzing the geometric shape data of rice leaves in the growth process, a model of the dynamic relationship between the geometric shape parameters of the rice leaves and effective accumulated temperature was built, and the threedimensional model of rice leaves was constructed. The visual modelling which simulated thedynamic growth process of rice before heading along with the environmental temperature was obtained, by using OpenGL graphics interface with rice plant tiller topology. The simulation has a strong sense of reality and lays a foundation for developing a visual rice growth system.
