| 摘 要： | 本文通过对建立估测植被生物量遥感模型中所涉及的遥感信息参数与植被光合参数的关系分析，从理论和实验中阐明了反映植物长势的量发化植被指数和反映植物光合面积的叶面积指数，光合有效辐射及吸收光合有效辐射的相互关系，对在实际中建立更为机理的生物量遥感模型提供可供进一步参考的依据。

| Abstract: | Biomes estimating model based on remote sensing information must contact with the plant photosynthetic parameters, these factors include crop photosynthesis characteristic, Photosynthetic Active Radiation (PAR) impacting on crop and Absorbed Photosynthetic Active Radiation (APAR). The remote sensing information includes the Normalized Difference Vegetation Index (NDVI), Leaf Area Index (LAI). In the paper, process from the information parameter of remote sensing and the parameter of plant physiologically, the relationship models among LAI, APAR, PAR and NDVI were analyzed. And this will be available to further establishing biomes estimate model. |
