| 英文摘要 | The impact of climate change on rice yield in China remains highly uncertain. We examined the impact of the change of maximum temperature (T-max) and minimum temperature (T-min) on rice yields in southern China from 1967 to 2007. The rice yields were simulated by using the DSSAT3.5 (Decision Support System for Agro-technology Transfer)-Rice model. The change of T-max and T-min in rice growing seasons and simulated rice yields as well as their correlations were analyzed. The simulated yields of middle rice and early rice had a decreasing trend, but late rice yields showed a weak rise trend. There was significant negative correlation between T-max and the early rice yields, as well as the late rice yields in most stations, but non-significant negative correlation for the middle rice yields. An obviously negative relationship was found between T-min and the early and middle rice yields, and a significant positive relationship was found between T-min and the late rice yields. It indicated that under the recent climate warming, the increased T-max brought strong negative impacts on early rice yields and late rice yields, but a weak negative impact on the middle rice yields; the increased T-min had a strong negative impact on the middle rice yields and the early rice yields, but a significant positive impact on the late rice yields. It suggested that it is necessary to adjust rice planting date and adapt to higher T-min. (C) 2015 Elsevier Ltd. All rights reserved. |
