The Construction of Greenway Ecological Network Coupled with Urban Space - Taking Zhengzhou Central Urban Area as an Example

Based on the study of urban spatial development in central urban area of Zhengzhou, this paper analyses the greenway space and its status quo of Zhengzhou central urban area via remote sensing technology and field supplement research, to find out the potential structure in construction of the greenway ecological network of Zhengzhou central urban area. With comparative analysis of network structure and landscape pattern analysis as the technical support, it then establishes network ecological model based on the theory of graphic theoretic connectivity, makes comparative analysis of ecological network model, thus constructing the optimal network structure for greenway ecological network of Zhengzhou central urban area. It is expected that there will be certain positive effect on green infrastructure construction of Zhengzhou central urban area.
