摘要: Abstract Field measurements of primary production in semi-arid grasslands three Sahelian countries over a period 8 years are analysed conjunction with multitemporal sums vegetation indices derived from the NOAA spacecraft's advanced very high resolution radiometer (AVHRR). The results demonstrate that there is strong linear relationship between satellite observations and seasonal range 0-3000 kg ha−. confidence intervals estimation were ±61-161 kg
