中文摘要干热河谷是横断山区的一类典型生态退化区域,逐年分季节降水量(SP)的变化对其景观格局及农业生产活动具有重要影响。运用年际增量方法把南方涛动指数(SOI)与降水量联系起来,建立了一个预测局地降水的新方法:把1958~2002年分季节南方涛动指数年际增量(SOIII)作为预测因子,采用多元线性回归方法建立一个干热河谷分季节降水年际增量的预测模型,模型通过了F检验、R检验、T检验和DW检验等显著性检验,在1958~2002年的模拟及2003~2008年的后报中显示了很高的预测能力。因此,此方法能显著地提高局地降水预测水平,并具有潜在的应用价值。
英文摘要The dry-hot valley is a kind of special degradation ecosystem region in Hengduan mountains.The changes of seasonal precipitation (SP) have important influence on its landscape patterns and agricultural activities.It establisheds a new prediction method of local precipitation through linking Southern Oscillation index (SOI) and precipitation based on the method of annual increment (II).Through the forecast of annual increment of Seasonal Precipitation in dry-hot valley of Yuanmou in Yunnan,then it predicted the precipitation.It has identified the annual increment of Seasonal Southern Oscillation index as predictors during 1958~2008,and adopted the method of multiple linear regression to establish a seasonal interannual increment precipitation forecast model of dry-hot valley.The forecast model passes the R test,F test,T test,DW test,such as tests of significance.It can not only reflect the T130 precipitation features and abnormal years and seasons,but also successfully simulatte its the interannual chenge of rainfall anomaly percentage and the seasonal to trend in dry-hot valley.So,the new method which it predictes predication through the forecast of the interannual increment precipitation,can significantly improve the level of local precipitation forecast,and provide the potential application value.
