基于Landsat 8数据的龙竹冠层水平叶绿素含量反演研究
Inversion of Chlorophyll Content at Canopy Level of Dendrocalamus giganteus Based on Landsat 8 Data
摘要
Abstract
Taking Dendrocalamus giganteus in Xinping County of Yunnan Province as the research object,Landsat 8 OLI image as the main data source,combined with the measured data of 35 plots,based on the sensitiv-ity analysis of PROSAIL model parameters,the look-up table of leaf chlorophyll content(LCC)and canopy re-flectance of D.giganteus was established.The chlorophyll index(CI)and its ratio(CI/G)to the greenness index(G)were selected to invert LCC,and then the canopy chlorophyll content(CCC)was obtained by combining the leaf area index(LAI).The results show that the R2 for CI and CI/G inversion of LCC were 0.48 and 0.52,and RMSE was 11.09 μg/cm2 and 8.23 μg/cm2,respectively.The R2 for CI and CI/G inversion of CCC were 0.53 and 0.64,and RMSE was 0.50 g/m2 and 0.43 g/m2,respectively.The research results can provide technical support for re-gional monitoring of D.giganteus.关键词
