利用江西鄱阳湖周边10个县的村级层面调查数据,实证分析了气候变化对鄱阳湖地区水稻种植模式的影响。研究发现,长期的平均降水量对水稻种植模式具有显著的影响,长期平均降水量越多,单季稻种植的比重越低,双季稻种植比重越高。短期的极端天气事件对当年水稻种植模式影响不显著。
Based on the survey data of village level in 10 counties surrounding Poyang Lake in Jiangxi Province, this paper empirically analyzes the impact of climate change on the rice planting pattern in Poyang Lake area. The study found that the long-term average precipitation has a significant impact on rice planting patterns, the longer the average precipitation, the lower the proportion of single-cropping rice, the higher the proportion of double-cropping rice. Short-term extreme weather events had no significant effect on the rice planting pattern at that time.
