对不同类型冬小麦品种叶形空间分布参数进行了定量描述 ,建立了叶片形状、叶面积指数随生长期的变化、叶面积随高度的分布及叶倾角分布 (L A D)等叶形空间分布的模拟模型及推理系统 ,提出了叶片形状因子和长势模拟模型 ,单叶空间最高点、高度层间隔内累积投影叶面积及各组分的空间取向与叶倾角分布解析模型系统及其主要设计算法。上述模型为具有普适意义的冬小麦冠层结构机理模型 ,其推理系统可以精确计算任意高度层次的投影叶面积分布特性 ,是评价作物株形结构优劣判断群体结构合理与否的有力工具 ,同时对于解析和利用多角度遥感数据监测作物长势等也具有重要参考价值 The spatial distribution parameters of different types of winter wheat cultivars were quantitatively described. Leaf shape, leaf area index with the growth period, the distribution of leaf area with height and the simulation model of leaf space distribution such as leaf inclination distribution (LAD) And the reasoning system, the blade shape factor and growth simulation model, the highest single leaf space, the cumulative projected leaf area in the height interval and the spatial orientation and leaf inclination distribution analysis model of each component and its main design algorithms are proposed. The above model is a universal canopy structure mechanism model of winter wheat. Its inference system can precisely calculate the projected leaf area distribution at any height level. It is a powerful tool to evaluate the structure of the plant structure in the plant structure. It also has important reference value for analyzing and using multi-angle remote sensing data to monitor crop growth and so on
