【论文摘要】The rational allocation of functional areas is the foundation for addressing the sustainable development of cities. Efficient and accurate identification methods of urban functional areas are of great significance to the adjustment and testing of urban planning and industrial layout optimization. Firstly, by employing multi-source geographic data, an identification method of urban functional areas was developed. A quantitative measurement approach of the urban functional area was then established by considering the comprehensive effects of human-land, space-time, and thematic information to present the covering area of ground objects, public awareness, and empirical research. Finally, the Zhengzhou city, which locates in Henan province of central China, was used to test the method. The results show that the developed method is efficient, accurate and universal, and can identify urban functional areas quickly and accurately. We found that the overall distribution of Zhengzhou's functional areas presents a spatial pattern of single and multi mixed coordinated development. The city's commercial functional areas and commercial-based mixed functional areas are located in the city's central area. The green square's function area occupies relatively low and is mainly distributed in the city's fringe.
