基于HJ-IA CCD数据的辐射传输模型反演叶面积指数研究
Research on the Inversion of Leaf Area Index Based on Radiative Transfer Model of HJ-IACCD Data
摘要
Abstract
With Gonger prairie of Kesiketeng flag of Chifeng City in Inner Mongolia autonomous region as research object ,the CCD data of HJIA was used for inversion of leaf area index (LAI). On the basis of Bayes theory,by using radiative transfer model PROSPECT and SAIL model,the inversion effect chart of LAI was obtained through regression inversion of LAI. Simultaneously,the inversed IAI was tested using wild synchronous determined ground data. It was found that the observed and inversed LAI possessed better consistency and their correlation coefficient was up to 0.696. The error was analyzed finally. The results showed that the inversion of LAI using the CCD data of HJ-IA could reflect ground condition better and it possessed higher application value and broad application prospect.关键词
