摘要
利用新疆北疆地区不同草地类型上观测的草地可食产量、环境与遥感资料等，使用3S技术进行了相关分析和遥感估产及预报，建立了地面光学和线性或非线性遥感估产及产量预报模型，在实际估产和产量预测中加以应用、检验，并给出了生态学解释。
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.
