| 中文摘要: |
| 收集黄土高原区域近40 a各主要气候要素变化资料并利用Petitt方法计算变点,滑动t检验气候变点或转折点,以分析判断黄土高原对全球气候变化响应的敏感性及敏感区域。结果表明:黄土高原降水、气温、土壤干旱、气候生产力等气候要素对全球气候变化响应的敏感区主要集中在高原中部附近,敏感区要素变化以24 a的年际振荡为主。 |
| 英文摘要: |
| The response sensitivity of climate in Loess Plateau in China to global change was investigated with the meteorological data during the recent 40years，and the marked change points were calculated by Petitt method，and checked by moving T-test．The results showed that the sensitivity areas of responses of precipitation，temperature，soil-aridity and climate-productivity were mainly concentrated in around the middle part of Loess Plateau By using wavelet analysis，about2～4years period was verified for the change of sensitivity areas. |
