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%.
