摘要
Mann-Kendall和滑动T检验法是近年来被广泛应用的特征分析方法,为了提高研究精度和准确度,将两种方法结合起来,以M法确定突变节点,用滑动T检验M法结论的准确性。穆棱河作为黑龙江省的十大河流之一,近年来流域附近对水资源的开采程度日益加大,因此,研究该流域径流变化具有十分重要的意义。
The characteristic analysis method of M-K and sliding T are both widely used in recent years. These two methods are combined in order to improve the research accuracy. The method of M-K is used to make sure the abrupt runoff change time point, and then the results accuracy of which is validated by method of slide T. Muling River is one of the most important river in Heilongjiang province, the water resource exploitation degree of which increases daily in recent years. So, it is extremely significant to research this basin water resource.
