摘要：Through the monitoring of the riverbed temperature in the Xi'an subsurface flow in the Weihe River, Shaanxi Province in the spring and autumn, based on the analytical solution of the one-dimensional steady-state vertical heat transfer problem, the water exchange flux and the surface water temperature are given by the temperature tracer method. Parameters, and explain the distribution of the depth of the submerged zone by the relationship between the groundwater temperature and the depth of the submerged zone. The results show that the distribution of latent flux is 99.61~356.25L/(m2 d), which obeys the normal distribution. There are large differences in the values of different positions in the same section, there is a concentrated discharge area, showing significant spatial heterogeneity, and the river channel. The heterogeneity of the bank is more significant than that of the bank; the depth of the submerged zone is inversely related to the amount of latent flow. The greater the latent flow, the smaller the depth of the submerged zone.
