摘要
利用洪泽湖湿地1961—2009年气象和农作物生产资料,分析了该区域气候变化特征及其对农业生产的影响及对策。结果表明:近49年,年平均气温呈现上升趋势,以近25年上升较为明显;年降水量缓慢增加;年平均日照时数明显下降。近10年来,极端气候事件频发,极端高温和低温年份交替出现,降雨量增加,旱涝年份交替出现,日照时数大幅度减少,相对湿度明显降低,气象因素变化给农业生产带来诸多不利影响。针对气候变化提出如下对策和建议:加强防灾减灾能力建设,调整农业结构和布局,改革种植制度,发展生态农业,选育和推广适应气候变化的农作物新品种。
Based on the annual climatic and agricultural production data from 1961 to 2009 in wetlands of Hongze Lake, the influence and countermeasure of climate changes on agricultural production in this area were analyzed. The results showed that the annual mean temperature increased, especially the temperature in recent 25 years increased obviously, the annual precipitation increased slowly, and the annual sunshine hours decreased in recent 49 years. In recent 10 years, the extreme weather events happened frequently, meanwhile, the extreme high-temperature and ex- treme low-temperature occurred alternately in different years, as well as the drought and flood years, and the annual precipitation increased gradually, on the contrary, sunshine hours and relative humidity greatly reduced annually, leading to much harmful influence on agricultural production. Thus, the corresponding countermeasures were pro- posed such as enhancing the ability of disaster prevention and mitigation, adjusting the distribution and structure of agriculture, reforming the cropping system, developing the ecological agriculture, breeding and popularizing new crop varieties adapt to climate change.
