全球稻谷主产国遥感估产可行性研究

Feasibility Research on Estimating Global Paddy Yield Using Remote Sensing

摘要: 利用NOAA气象卫星的序列资料，对全球稻谷遥感估产的可行性进行了探讨。并以泰国、美国、越南为例，分别对NDVI植被指数与产量进行相关分析，取得良好的应用效果。此外，还应用数理统计方法对全球稻谷的历史产量进行数学模拟，达到较高的拟合精度。

Abstract: Utilizing the relationship between the global NOAA data and paddy yield data during the period of 1985~1990, an estimating yield model was obtained. These models were applied to estimate paddy outputs in U. S. A. , Thailand and Viet Nam. The results are satisfactory. Furthermore, the global paddy yield during the period of 1979~1994 was simulated by using the statistical method, the fitting accuracy can reach above 98%.
