Abstract：In this paper,we based on four sets of 30m spatial resolution land cover products and sample point datasets of land cover types in Fujian Province in 2019, this study analyzed the area consistency by deviation coefficient and correlation coefficient, and analyzed the spatial consistency and type confusion degree by error matrix and the overlappingof products. The results showed that the correlation coefficients among all four sets of land cover products were high, and the portrayal of Fujian Province was basically consistent, with less deviation on four types of forest land, water bodies, artificial surface and cropland, and the deviationsof grassland, shrubland, wetland and bare land were large.The overall accuracy was CLCD (84.89%) > FROM-GLC30 (81.90%) > GLC-FCS30 (81.75%) > GlobeLand30 (72.95%), with higher produce accuracy and user accuracy and lower type confusion for forest, water bodies and artificial surfaces; in short, forestis the best performing land cover type. In general, attention should be paid to the application of land cover products in fujian province based on different application requirements.
