Research on urban greenway planning in the old city of Jinan City based on GIS interpretation and gravity model data

Urban greenway planning is not only an important part of the construction of ecological cities and urban forest ecological network systems, but also a necessary means and an effective way to build urban ecological gardens and ecological green space systems. The link of the city plays a vital role in protecting the cultural and ecological civilization of the old city, and protecting the ecological environment, natural landscape, cultural relics and historical sites and local features along the line. This study selects the old urban area of Jinan City as the research area, uses GIS (geographic information system) remote sensing interpretation, conducts data analysis, conducts comprehensive performance evaluation of the area, selects the best connection paths and landscape nodes, and establishes the gravity model of urban greenways.
