本研究以天津市冬小麦估产为模式
阐明了NOAA/AVHRR资料应用于中小尺度地区农业产量预报的可行性。在分析资料时
运用水面的光谱值校正大气因子
采用地理现状底图排除混杂因素
使资料趋于稳定;在利用植被指数与产量因子建立各种回归预报方程时
进行了区域订正和积温订正
从而使预报准确率达到95%左右。
With the crop estimation for winter wheat in Tianjin City area as a model
this paper elucidates the Application feasibility of NOAA/AVHRR information to predict the crop in small and medium sized area. In data analysis
spectroscopic values obtained from water surface are used to correct atmospheric factors
and the geographic contour map is used to eliminate confused factors
thus the data tend to be stabilized. By utilizing the vegetation index and yield factor
some regression equations for forecast are suggested with the green values corrected according to different area and integrated temperature. Then
an accuracy of 95% for forecast may be obtained.
