| 摘 要： | 基于塔里木河流域及周边29个站点1980～2004年日降水资料分析了降水量时空变化规律,采用Mann-Kendall检验法研究了流域降水量的变化趋势.结果表明,该流域降水稀少且分布不均,主要集中于夏季,空间分布由东南向西北逐渐增加,在西北部边缘形成一个相对丰水带,且在丰水带上的降水量增加较为显著,而接近沙漠腹地地区的降水则呈减少趋势.

| Abstract: | Based on the daily precipitations from 1980-2004 at the 29 weather stations in and out of the Tarim river basin,spatial and temporal variation of precipitation was analyzed with Mann-Kendall rank correlation test method and linear regression method.Results show that precipitation mainly concentrated in the summer,which accounts for about 58.9% of annual precipitation.Over the spatial variation,precipitation has increased from southeast to northwest gradually,and formed a high rainfall belt on the northweste... |
