摘要：

 快速、可靠、精确地评估植被冠层结构参数在大气-植被相互作用的研究中起着举足轻重的作用。为探明鱼眼影像在水稻冠层结构研究中的应用前景, 本研究选择3种不同冠层结构的水稻品种作为研究对象, 利用带有鱼眼镜头的数码相机在冠层的8个不同高度分别拍摄冠层影像, 通过对影像的预处理提取冠层间隙度参数, 根据冠层内辐射环境与冠层结构之间的定量化关系, 利用Beer-Lambert定律反演水稻冠层的叶面积指数(leaf area index, LAI)和平均叶倾角(mean leaf angle, MLA)。研究结果表明, 鱼眼影像反演的LAI均方根误差(root mean square error, RMSE)为1.2~1.5, 相对误差(relative error, RE)为18.6%~22.5%, 仅比人工测定结果低估7.6%~13.1%, 优于Sunscan的测定结果。其次, 反演的MLA与人工测定结果之间有较好的一致性, 相关系数为0.9205**, RMSE为11.7°, RE为16.1%。研究结果表明, 鱼眼影像反演水稻冠层结构是可行的方法。

Abstract:

 It is important to find a fast, reliable and accurate method for estimating canopy construction parameters in the study of vegetation-climate interaction. In the present study, three rice varieties with different canopy structures were chosen as experimental materials. A digital camera with a fisheye lens was used to take photos in eight heights of rice canopy to develop a new approach for concluding rice canopy. Canopy gaps were extracted from those photos, and then leaf area index (LAI) and mean leaf angle (MLA) could be inversed by Beer-Lambert theory, based on the quantitative relationship between the radiation condition and the canopy structure. Results showed that LAI inverted from the hemispherical photograph was 7.6%–13.1% less than that measured manually, and the root mean square error (RMSE) between them was 1.20–1.45. The data showed that hemispherical photography was better than Sunscan canopy system. Moreover, MLA inverted from the hemispherical photograph was related to that measured manually with 0.9205** of correlation coefficient and 11.7° of RMSE. Therefore, hemispherical photography is a feasible technology to indirectly measure the rice canopy structure.
