ABSTRACT
Sichuan province is one of
the 13 major grain-producing provinces in China and also an obvious region of
climate change. In this study, the responses of single cropping rice yields to
climate variables under climate change at each development stage were
investigated by using the linear regression method based on yield and climate
data at 84 counties in Sichuan province of China from 1981 to 2012. The results
indicated that change of all climate variables (increase of average temperature
and diurnal temperature range, and decrease of precipitation and solar
radiation) during different development stages in recent 30 years caused
significant change of yield in less than 10% of the rice planting area.
However, climate change from 1981 to 2012 had caused significant impacts on
rice yield in roughly 47.6% of the rice area, with yields fluctuating by -11.77%
to 24.55%. Moreover, average temperature was the most key contributor for the
impact on rice yields in all climate variables and solar radiation was the most
key contributor for the negative impact on rice yields. The empirical findings
presented here provide a foundation for anticipating climate change impacts on
rice production.
