Abstract:

To understand the relationship between the rice yield and climate factors of Heilongjiang Province, by using the SPSS software, analyzed the correlation between the temperature, precipitation, relative humidity and the rice yield, the correlation of the difference year after year of the temperature, precipitation, relative humidity and the rice yield of Heilongjiang Province from 1980 to 2010. The results showed that, the respective correlation coefficient between the rice yield and the daily average temperature, precipitation and relative humidity was 0.399, -0.380 and -0.422. They all correlate significantly above the 0.05 level, and with the order of impact on rice yield is the daily average temperature, precipitation and relative humidity. And the respective correlation coefficient between the year after year differences of them were 0.680, -0.650 and 0.600. They all correlate significantly above the 0.01 level, and with the order of correlation coefficient of the year after year difference with rice yield was the daily average temperature, precipitation and relative humidity.
