| 中文摘要: |
| 以1981~2000年甘肃全省71站点马铃薯产量和生长期气象资料为基础数据,用EOF、多元回归、积分回归等统计分析方法分析该省马铃薯产量年际及地域变化特征,以及不同气象因子对马铃薯产量的影响。结果表明:陇中和陇南山区产量序列与该空间型的时间系数序列的相关不显著,产量年际变幅小;其余地方产量序列与该空间型相关显著,产量年际变幅大。在降水量变化一定的条件下,马铃薯产量随温度的升高而降低,在温度变化一定的条件下,马铃薯产量随降水的增加而增加。 |

| Based on the potato yield data and meteorological data during 1981～2000 from 71 stations of whole Gansu province,we analyzed the time-space characteristic of the potato yield change and the weather factors affecting the potato yield using the EOF,multivariate regression and integral calculus return to return etc.,built up the weather-yield estimation model,put forward the corresponding countermeasures.The results showed that: the yield sequence and the time coefficient sequence of the space type in Longzhong and Longnan area were not significantly correlated.The yield change from year to year had a little scope.In the other areas,the yield sequences and the space types are significantly correlated,and the potato yield changed yearly greatly.Under condition with certain precipitation amount,the potato yield increased as the temperature went up,under condition with certain temperature,the potato yield increased as the precipitation rose. |
