植被碳同化估测与遥感信息的关系研究

The relationship between estimation of vegetation carbon assimilation and remote sensing information

摘要: 简析了估测植被碳同化遥感一光合机理模型的重要性，阐述了遥感信息反演的参数与植被碳同化的关系，其中包括归一化差值光谱植被指数(NDVI)、叶面积指数(LAj)、吸收光合有效辐射(APAR)、热红外辐射(TIR)等与植被碳同化之间关系，为建立全遥感一合机理碳同化模型，应用遥感信息估测植被碳同化提供依据。

Abstract: The relationships among vegetation carbon assimilation and remote sensing information such as NDVI(normalized difference vegetation index)，LAI(1eaf area index)，APAR (absorbed photosynthetically active radiation)，and TIR (thermal infrared radiation)were analyzed in this paper．It will be essential to establish the estimation model of carbonasimilation using remote sensing information and photosynthesis mechanism ，and serve as an independent comparison to more detailed eco-physiological models of biological proces ．
