摘要
选取中国西部农业大县射洪县作为区域气候变化研究对象,从粮食产量、种植结构等方面分析区域气候变化对农业生产的影响,同时分析气候变化之外的人为因素对农业生产的影响。结果表明,降水量对农业生产影响不大;种植结构主要受气温影响,年平均气温在1968-2002年对粮食产量产生显著影响;种植结构在1951-1968年和1977-2003年两个阶段受人为因素影响明显。
Taking a large agricultural county in west China,Shehong county,as research object,the impact of regional climate change on the grain output and planting structure was studied;meanwhile,the impact of human factors on agricultural production was analyzed.The results showed that precipitation had a little influence on agricultural production;but temperature affected the planting structure obviously,and had a significant influence on the grain output from 1968 to 2002.Human factors had significant influence on the planting structure in the stages of 1951 to 1968 and 1977 to 2003.
