Abstract

The invention discloses a vegetation index fusion method based on multi-source data, and the method comprises the following steps: S1, carrying out the spatial rasterization of a field vegetation coverage data set through employing a geographic regression weighting model, and obtaining a field vegetation coverage raster data set; S2, acquiring related data of the research area influencing the surface vegetation coverage, and calibrating a biogeochemical model Biome-BGC based on the related data to obtain a daily-scale vegetation coverage raster data set; S3, obtaining the vegetation coverage collected by AVHRR and MODIS sensors of the Terra satellite in the research area, and carrying out scale conversion on the vegetation coverage to obtain a vegetation coverage raster data set of a ten-day scale; S4, based on the three data sets, constructing and solving a vegetation index fusion model to realize fusion of multi-source vegetation data; according to the method, the problems of low temporal-spatial resolution and estimation precision of the surface vegetation coverage are solved.

Description

technical field [0001] The invention relates to the technical field of ecological remote sensing, in particular to a vegetation index fusion method based on multi-source data. Background technique [0002] Vegetation coverage is an important indicator of surface vegetation coverage. It is closely related to surface vegetation coverage, soil erosion, land desertification, and global climate change. It is an important parameter for ecological environment change, global and regional climate models. Therefore, it is of great practical significance to obtain higher spatial and temporal resolution of surface vegetation coverage and its change information for revealing the law of surface space change, exploring the driving factors of change, and analyzing and evaluating the regional ecological environment. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the invention provides a vegetation index fusion method based on multi-source d...
