The method provided by the invention includes the following steps: 5 (1) Obtaining the Permeability coefficient of different substrates: arranging the monitoring points, monitoring seepage quantity per unit area and per unit time of different types of wetlands by using the wetland seepage quantity measuring devices to obtain permeability coefficient. (2) Determining the area parameters of different wetland substrates: Wetland boundary 10 and a wetland soil texture chart were overlaid by using ArcGIS software to obtain the area parameters of different wetland substrates. (3) Calculating the wetland seepage quantity : Using formula (1) to calculate wetland seepage quantity. The method of the invention improves the traditional calculation method of the wetland seepage quantity by using means of empirical parameters. Field 15 monitoring which can correct experience parameters is designed to achieve accurate calculation purposes.
