【摘要】 根据气象环境对水稻进行估产是水稻非遥感手段估产的方法之一。寻找精确且有效的算法是上述方法的关键环节。本文讨论了设计上述算法的基本方法和提高算法精度的途径。并结合苏州市和扬州市水稻单产设计了市、县两级两种估产算法,找出了有效气象参数系列,近三年的预报精度达到97%以上。更多还原

【Abstract】 According to meteorological conditions to estimate rice production is one of important non-remote sensing methods.It is a key step to look for an algorithm with high efficiency and precision.This paper had discussed the basic method of designing.this algorithm and increasing its preciesion.Otherwise,two algorithms for estimating rice production of county and region are designed and pratically used to estimate rice production in Yangzhou region and Suzhou region.Through analyzing result of the above estimation,we have found some efficient meteorological parameters used in these algorithms.In fact,the rightness of these algorithms had been verified.Three years application of these algorithms has also shown that the correlation coefficient between results and the statistical figures is above 97%.更多还原
