受水稻抽穗后冠层几何和光谱特征复杂性的影响,基于传统植被指数的遥感方法难以对水稻稻穗的生物量进行精确估算。基于无人机平台获取的光合有效辐射区域吸收系数,通过分析水稻抽穗后对不同波段光合有效辐射吸收能力的变化,建立基于光合有效吸收的穗生物量估测模型。结果表明,基于蓝红吸收差值指数建立的模型相较于传统的植被指数经验模型对穗生物量有更优的估算精度,对于2018年海南试验田获取的数据,该模型的决定系数(R2)为0.83,均方根误差(RMSE)为147.50 g/m^(2),变异系数(CV)为10.19%,跨年跨地测试的R^(2)为0.72,证明该模型具有良好的迁移能力。因此,基于光合有效吸收的穗生物量估测模型实现了稻穗生物量的遥感准确估测,有助于提升农作物大面积估产精度与估产效率。

目的:探讨原发性上斜肌亢进(PSOOA)患者眼球客观旋转与双眼近立体视功能之间的关系。方法:回顾性研究。收集2019-01/2023-11于我院行斜视手术并存在PSOOA的斜视患者共59例,采集眼底照相图片,根据黄斑中心凹与视乳头水平经线的相对位置将眼球分为内旋、外旋和无旋转组,进一步测量黄斑-视乳头夹角(FDA),并分析眼球客观旋转情况及FDA与患者近立体视功能的关系。结果:患者59例92眼存在上斜肌亢进。眼球外旋0例,眼球无旋转32例,眼球内旋27例,眼球无旋转组双眼总FDA明显小于眼球内旋组(2.83°±2.89°vs 16.12°±5.74°,P<0.001)。眼球无旋转组和内旋组近立体视保存率分别为66%和15%,差异显著(P<0.001);眼球无旋转组和内旋组精细近立体视保存率分别为38%和11%,差异显著(P=0.02)。所有患者近立体视与双眼总FDA存在相关性(r=-0.526,P<0.001),与内旋眼FDA相关性最大(r=-0.546,P<0.001);眼球内旋组近立体视与双眼总FDA无相关性(r=-0.366,P=0.060),与内旋眼FDA和亢进眼FDA负相关(r=-0.424,P=0.028;r=-0.485,P=0.010);眼球无旋转组近立体视与双眼总FDA、主导眼FDA、非主导眼FDA、亢进眼FDA和非亢进眼FDA均无相关性。结论:PSOOA患者出现眼球内旋者较眼球无旋转者近立体视功能保存率更低,近立体视功能与双眼总FDA负相关,尤其是内旋眼和亢进眼FDA越大,近立体视功能越差。
