摘　　要：强涌潮河口水体交换能力与其水动力状况密切相关,而影响强潮河口水动力状况的因素众多。因此为保证强潮河口水体的正常生态功能,开展水体交换能力的敏感因素分析,研究水环境容量十分必要。以钱塘江河口为例,在钱塘江二维数值模型的基础上,采用浓度示踪法对强涌潮河口水体交换能力的影响因子)径流、潮汐、江道地形及岸线进行了敏感因素分析。The exchange and transit capacity of water, among many other factors, is closely related to the hydrodynamic condition in strong tide estuary. In order to ensure the normal ecological function of strong tide estuary, it is necessary to study water environment capacity through sensitive factor analysis of water exchange capacity. Taking the Qiantang River estuary as an example, the paper conducted sensitive factor analysis with concentration tracer method based on the two- dimensional numerical model of the Qiantang River. The sensitive factors include runoff, tide, topography and coastline.
