采用新安江水库建库前后及钱塘江河口治江缩窄前后的实测氯度资料分析了大型调节水库增加了枯水径流 ,治江缩窄改变了潮汐特性和进潮量这两类人类活动对咸水入侵的影响 ,又采用一维咸水入侵数学模型进行了上述影响的验证和计算分析 ,结论基本一致。
The measured chlorinity before and after the construction of Xin’anjiang reservoir before and after the construction of the Qiantang River estuary and the regulation of the river were analyzed. The large-scale regulation reservoirs increased the runoff and the narrowing of the river changed the tidal characteristics and the tidal volume. Invasion and the use of one-dimensional salt water intrusion mathematical model to verify the impact of these calculations and analysis, the conclusion is basically the same.
