Abstract: NDVI-based grassland biomass model has been widely used for evaluating the growth and productivity of grassland communities, since remote sensing technology can be used for timely monitoring of wider areas. Based on existing literature on regression relationships between grassland biomass and NDVI published during 2000 – 2018, we built the dataset of regression relationships between grassland biomass and NDVI in China. The dataset contains 17 types of grassland regression relationships between biomass and NDVI, and each relationship type contains 4 kinds of regression expression, namely, unitary linear, power function, exponential and logarithmic relationships. Besides, it also contains information on grassland zoning, grassland distribution, biomass suitable period, NDVI data resources, NDVI temporal-spatial resolution. This dataset provides important data resources for evaluating grassland productivity, grassland ecosystem carrying capacity, carbon cycle studies, and ecological protection in China.
