A field investigation has been made of the utilization of the space under the 24 overpasses within the third ring road of Zhengzhou city (including the third ring road). The research results show that the utilization modes of the space under the overpass bridges within the third ring road in Zhengzhou city are mainly facilities for municipal afforestation, parking, transportation, commerce and public services. Meanwhile, there exist such flaws as low utilization rate of space under the overpass bridges, poor coordination with their surrounding environment, unitary planting pattern, monotonous spatial color, lack of regional characteristics and overall management. The reasonable utilization of the space under urban overpass in Zhengzhou city requires a full consideration given to the surrounding land types and the public service facilities under the overpass bridges, thus creating a landscape greening under the bridges with ecological and aesthetic functions and unique landscape features, so as to meet the diversified requirements of urban residents, with its management system optimized and improved.
