| Abstract: | Using the green herbage yields, environment and the remote sensing (RS) dataobserved in different grassland types in Fukang County, Xinjiang from 1994 to 1997, thecorrelation analysis and the estimating yield methods were studied by measns of 3S technology. The methods of images processing, information collecting and using information, linksof RS data and grassland data were further developed in this paper. The results show thatthe total accuracyes of the remote sensing estimating and forecasting green yields were above75 % in large areas. |
