| 摘 要： | 本文以上海城市森林为研究对象,采用地面实验与遥感技术相结合方法,开展SPOT5遥感影像在估测城市森林LAI中的应用研究。结果表明,地面实测LAI与三种植被指数均具有很好的线性回归关系,相关系数(r)均大于0.6,其中MSAVI的相关系数最高(r=0.66),其次为MCARI(r=0.64)和NDVI(r=0.62)。说明ND-VI仍受到背景等因素不同程度的影响,而植被指数MSAVI和MCARI,由于能进一步消除土壤背景和叶绿素的影响,对叶面积指数比较敏感,能更好地与叶面积指数建立关系,能更好地用于城市森林叶面积指数的遥感反演。本研究可为快速定量评估城市森林的结构和功能提供依据。

| Abstract: | In this paper, based on field experiment and remote sensing technology, estimation of urban forest LAI was studied based on SPOT5 image in Shanghai. The correlation coefficient between LAI and MASVI, MCARI, and NDVI were 0.66, 0.64, and 0.62, respectively. The study showed that MASVI and MCARI were better than NDVI in analyzing urban forest LAI. Using SPOT5 high spatial resolution data could efficiently distinguish the ground objects and could improve the accuracy of radiometric calibration and quantification of remote sensing. This study shows that the SPOT data can be used for inversing urban forest LAI. It provides a good method and theoretical basis for evaluating urban forest structure and function. |
