【 摘 要 】

In order to accurately reflect the basic characteristics of the water quality of the different reaches of the Weihe River (Shaanxi section), this paper selects ammonia nitrogen, CODcr, total phosphorus, and total nitrogen, which are more serious and concerned about exceeding the standard in the surface water of the Yellow River basin based on a large number of survey data, draw the curve of four water pollution indicators along the Weihe River (Shaanxi section) in different water periods, and grasp spatially the environmental changes of different parts of the Weihe River (Shaanxi section), different upstream and downstream parts. And the contrast of quality changes, so that the river water quality evaluation is typical and representative, provide a basis for the comprehensive management of the Weihe River basin, and promote the sustainable development of the Guanzhong region.
