Abstract: Through stratified random sampling, the structure features, configuration mode and health status of street trees in eight urbans of Zhengzhou city were investigated. The results showed that there were 39 species of street trees, belonging to 22 families and 30 genera, the ratio between evergreen and deciduous trees was 1:6.8. The high frequency of street trees were Platanus hispanica(48.46%), Sophora japonica(10.38%), Koelreuteria integrifoliola(8.85%), Ligustrum incidum(8.46%) and Fraxinus chinensis(6.54%), and the diversity index was 2.225. Single carriageway with two green belts pattern occupied the main forms. The ratio of single-layer model was 66.91%. The proportion of street trees growing above average was 83.48%. According to the current situation of Zhengzhou, the existing problems can be improved by increasing the number of tree species, enriching the allocation mode and strengthening management and maintenance.
