THE PREDICTION OF THE YIELD OF CROPS WITH REMOTE SENSING SPECTRUM MFTHOD

The remote sensing spectrum method takes the mathematical statistical sampling survey as its principle, the regression analysis as its mathematical base and thec rop spectrum reflection rate of remote sensing technique as the measuring method. This is one the methods to predict the crop yield with large-sized area. The author has used this method to predict the rice and wheat yield very accurately for four counties and one state farm distributed at southern and northern part of China for three years.The method for predicting the yield of crops has been proved that it can be used not only at different parts of a country with various climatic conditions but also with different topographies and different sizes of crop areas.
