| 摘 要： | 选取呼伦贝尔市16个代表站的降水资料,用地统计方法、墨西哥帽小波分析和一些常规统计方法进行降水时空分布分析。结果表明:呼伦贝尔市多年平均降水量分布特征是山区大、平原小,东南部及北部降雨降水量大、中西部及东部地区降水量小;年降水量有上升的趋势但有部分地区呈减少趋势,年降水存在着8~12 a、2~4 a年的周期变化。 |

| Abstract: | Based on the annual rainfall data from 1971 to 2000 of 16 weather stations,the spatial structure and changes of rainfall and the multi-time scales characteristics of annual rainfall in the Hulunbuir were analyzed using Mexican Hat wavelet analysis and methods of geo-statistics.The results indicated that the distribution of rainfall in the Hulunbuir showed obviously regional difference;The characteristic distribution of the multi-year average precipitation in Hulunbui was that: The rainfall is larger in the mountainous regions than in the plain regions,larger in the southeast part and Northern part than in the Middle-west part and Eastern part.The change trend of yearly rainfall increased.There are obvious periodic oscillation of 8-12a and 2-4a for annual rainfalls variation. |
