为了认识和应对气候变化问题,本研究以1978-2008年东北地区小麦、玉米、稻谷的种植面积和单位面积产量数据为基础,分析了粮食作物播种面积比重、粮食作物种植结构的变化,应用线性回归分析方法对比分析气候变化对小麦、玉米、稻谷单产的影响差异。结果表明,在全球变暖驱动下,东北地区农业种植正在发生适应性变化,种植面积的扩大是人类主动应对气候变化的表现。研究发现,这种农业适应是公众自我实行而非政府有计划推行的。借助这个经验,笔者认为针对东北地区农业适应气候变化现象,提出了以公众参与应对气候变化为核心,作为公众的组成部分农业企业和农村居民应该更有计划地参与行列里面来,其中包括改造农业设施、推广新型品种,以更有效地应对和适宜气候变化。
In order to seek the solution to deal with climate change issues, data set including acreage and yield of wheat, corn and rice from 1978 to 2008 in northeast China were collected. Based on these data, the author investigated the proportion of grain sown area and grain cultivation structural changes. The impact differences of climate changes on wheat yields, corn yields, and rice yields were analyzed by adopting linear regression analysis and comparative analysis methods. It was found that global warming drove the agricultural planting structure adaptive changes took place in northeast C.hina. This was people' s initiative to tackle with climate change performance. This study also found that the adaptation of agriculture was due to the public initiative rather than the government program. The author proposed that since public participation tended to be the core strategy to cope with climate change, as part of the public the agricultural enterprises and rural residents should be deeper involved in setting cultivation schedules as responds to the adaption of climate change in northeast China. For the purpose of responding and adapting to climate change more effectively, transformation of agricultural facilities and promotion of new varieties of crops should be adopted properly.
