In present study, GIS was adopted to noise zoning in Tangshan city based on Technical Specifications to Determinate the Suitable Areas for Environmental Noise of Urban Area (GB/T 15190-94) in China. According to the status of the built-up area in Tangshan, environmental noise area of Tangshan could be divided into Area 1, Area 2, Area 3 and Area 4. Their area were 21.02 km

and 23.52 km

, respectively, and area percentage in Tangshan city were 18.05%, 31.51%, 30.23% and 20.21%, respectively. Comparison the geographic distribution of the noise zoning with urban master plan, it showed that the noise zoning is in agreement with the urban master plan, which was benefit to the implementation of master plan, but also it is a supplement.
