摘要: The distributions of C3 and C4 grasses were used to interpret the distribution, seasonal performance, potential production grasslands in Great Plains North America. Thirteen major grassland land cover classes studied with data from three distinct sources. Normalized Difference Vegetation Index (NDVI) derived National Oceanic Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) sensor collected for each pixel over a 5-yr period (1989–1993), analyzed quantitative attributes relationships, then aggregated by class. Data State Soil Geographic (STATSGO) database identify dominant plant species contributing map unit. These identified as or C4, contributions provide estimates percentage intersection STATSGO units c...
