萨拉多河位于阿根廷布宜诺斯艾利斯省 ,全长约 6 90km ,流域面积约 80 0 0 0km2 ,平均年径流量为35亿m3,系典型平原性河流。萨拉多河有 3个入海口 ,其中 15号人工河自 1997年以来经疏浚后加宽加深 ,分流了大部分萨拉多河水量。为了研究萨拉多河在环境水文特性方面的变化 ,在 1997～ 1999年分 3个阶段采样测定了河水溶解质总量 (TDS)和离子化合物。研究结果表明 ,由于 15号河的分流作用 ,萨拉多河下游水量平衡被打破 ,致使其生态学条件有所改变 ,水文特性亦发生变化 ,进而引起局部人口的社会经济学条件也跟随发生改变
The Salado River is located in the province of Buenos Aires, Argentina. It has a total length of 6 90 km and a drainage area of about 80 000 km 2. The average annual runoff is 3.5 billion m3, which is typical of plain rivers. There are three estuaries to the Sarado River, of which artificial river 15 has widened and deepened since dredging since 1997, diverting most of the water from the Salado River. In order to study the changes in the environmental and hydrological characteristics of the Salado River, total dissolved matter (TDS) and ionic compounds in the river water were measured in three stages from 1997 to 1999. The results show that due to the diversion of river 15, the water balance in the lower reaches of the Sarado River has been broken, resulting in some changes in its ecological conditions and hydrological characteristics, which in turn cause the socio-economic conditions of the local population to also change
