| 摘 要： | 利用1971—2007年气象资料及相关统计数据,以喀什市为研究区域,运用主成分分析法,定量分析气候变化对粮食产量的影响。研究表明:粮食产量变化波动中上升;气候生产潜力偏低,自然因素在粮食增产中的影响比重越来越高;降水稀少、蒸发旺盛成为限制作物增产的主要因素。

| Abstract: | Based on the meteorological data and relative statistical datas from 1971 to 2007,with Kashi City as the study area,quantitative analysis of the impact of climate on grain yield was made by using principal component analysis.The results showed that the grain yield rose with fluctuation;climate productivity was lower,the proportion of natural factors in increasing grain production were higher and higher.Little precipitation and strong evaporation were been the main factors to limit grain yield. |
