摘　　要：以特定品种(偃展4110)小麦为研究对象,基于实测数据,完善了该品种小麦叶片的模拟模型及几何模型。首先,对其地上部的形态特征数据进行跟踪记录,并进行了特征参数提取;然后,基于实测数据进行叶片模拟模型构建,完善了该品种小麦叶片的叶长模拟模型与叶形模拟模型,并取得良好结果;最后,利用NURBS曲面建模技术对叶片进行几何模拟,并完成了叶片卷曲及扭曲等形变状态。本研究可为小麦三维动态建模提供技术支持,为田间管理与决策提供研究基础。Using specific wheat variety Yanzhan 4110 as material,the simulation model and geometric model of leaves were improved based on measured data. Firstly,the aboveground morphology data were tracking recorded,and the feature parameters were extracted. Then the leaf length and leaf shape simulation models were established and improved based on measured data,and good results were obtained. In the end,the leaves were conducted geometric simulation using NURBS surface technology,the leaf curl and twist models were also achieved. This research would provide technical supports for three- dimensional dynamic modeling of wheat and supply research bases for field management and decision.
