用气象卫星资料监测冬麦长势和估测产量的研究

利用１９９２、１９９３年的气象卫星资料，分析植被指数与甘肃省冬麦区３３个县市冬麦产量的关系，发现绿峰植被指数与产量存在极好的相关性。另外，从预测产量的角度和预报时限要求出发，可用４月中下旬累积植被指数预测冬麦产量，并给出了预报方程。

The Study On Monitoring Growing Tend of winter Wheat and Estimating its Yields Using Meteorological Satellite Data

By using of meteorological satellite data in 1992 and 1993,in this paper,it is analysed relation between vegetation index and winter wheat yields in 33 counties and cities of winter wheat region in Gansu Province. it is found correlation between vegetation index of green peak value and yield is very good. On the other hand, from the viewpoint of forecast-ing yield and forecast time limit winter wheat yields were forecasted by means of accumulated Vegetation index in the second and third decade of April Forecast equation was given.
