| 摘 要： | 本文利用长江口南槽1989年12个月的实测地形图和大通站相应的水沙资料,采用GIS技术和数理统计技术分析了南槽的地形变化及其与河流来水来沙的关系.结果表明南槽水深与大通站各月平均流量、输沙率和含沙量之间有明显的相关性,说明河口冲淤对流域水沙变化有敏感响应;河槽的响应具有1～1.5月的滞后性.

| Abstract: | By the data of the south passage of Changjiang River Mouth and the data of water and sediment in Datong
Station,and with the technology of GIS and mathematical statistics, we have analyzed the relationship of the change of the topography of south passage in Changjiang River Mouth and the water and sediment from Cangjiang River. The result has showed; there are good correlations between the mean month water depth in the south passage and the month mean riverine discharge, the mean month rate of the sediment and the mean month suspended sediment concentration and the riverine discharge, the rate of the sediment and the suspended sediment are lagged for the distance from Datong Station to the Changjiang Estuary. |
