Construction and Improvement of Urban Greening Space in Old Town Core Area Based on GIS Spatial Analysis Technology

Abstract

As China's urbanization process continues to accelerate, the land for urban construction is becoming increasingly tight, green spaces in urban landscapes are continuously eroded, and the ecological patches are seriously fragmented. It seems relevant to use community greenways as a platform for the path of urban ecological space integration and restoration. Taking the core area of the old city of Hefei as an example, the study applies the idea of eco-city as a guide, applies GIS spatial analysis technology, and derives a community greenway network based on the minimum landscape resistance value by selecting the resources of patches in the core area of the old city and calculating the landscape resistance value of urban land to improve the ecological quality of the city.
