松花江佳木斯站径流变化规律及演变趋势分析

Analysis of Change Rules and Variation Trend of Runoff of Jiamusi Station in Songhua River

以松花江佳木斯站为例,基于1953~2007年径流时间序列资料,采用累积距平法、累积滤波器和Mann-Kendall秩次相关法等,分析计算了年径流丰枯期、阶段性、径流年内分配不均、集中度和集中期及年径流、月径流的长期演变趋势,获得了佳木斯站径流年际变化特征、规律及演变趋势,为深入研究黑龙江下游的水文情势、生态环境保护、界河开发提供了依据。

Based on the runoff time series from 1953 to 2007 of Jiamusi Station in Songhua River,the wet and dry year condition,stage,non-uniform,concentration degree,concentration period of annual runoff distribution,long-term variation of yearly and monthly runoff are analyzed by using cumulative anomaly method,cumulative filter method and Mann-Kendall method.The variation characteristics and tendency of runoff in Jiamusi station is obtained,which provides basis for analysis of hydrological regime of the downstream of Heilong River,protection of ecological environment and development of boundary River.
