Study on Forecasting Methods of Corn Heat Index in Northeastern China (Ⅱ)——Stepwise Regression Model
摘要
Abstract
Using the 74 types of atmospheric circulation characteristics( ACC) ,monthly stepwise regression models of corn heat indexes from May, the sowing month, to August for 3 typical stations in 3 provinces of Northeastern China are developed. By the models, corn heat status in the growing season in each region can be fairly forecasted. The test results show that the accuracy of corn heat index forecast can be improved effectively by the method of monthly rolling forecast.关键词
