摘要
系统归纳分析了我国气候资源变化情况,总结探讨了气候变化对水稻生育期、产量、品质及生产成本的综合性影响,提出了水稻生产应对气候变化的适应性对策,主要是选育与选用适应气候变化的水稻新品种、调整水稻种植制度及品种搭配结构、适应气候变化的水稻群体管理措施和加强水稻生产过程在灾害性天气的预测预报及预防工作。此外,发现当前针对水稻生产应对气候变化措施的研究缺乏特定性及精确性,有待进一步深入和加强。
The changes of climate resources in China were summarized and analyzed systematically.The comprehensive effects of climate change on the growth period,yield,quality and production cost of rice were summarized and discussed.The adaptive countermeasures for the response of rice production to climate change were put forward,mainly selected new varieties of rice adapted to climate change,adjusted rice planting system and variety collocation structure,the rice population management measures adapted to climate change,strengthened the prediction and prevention of rice production process in disastrous weather.In addition,it was found that the current research on rice production response to climate change lacked specificity and accuracy,and need to be further deepened and strengthened.
