In order to explore scientific urban green space ecological planning methods to improve the sustainability of urban planning, this paper uses GIS technology combined with spatial analysis methods to analyze the ecological sensitivity of the region and utilizes the analytic hierarchy process (AHP) to construct a landscape resource evaluation system. By comparing the landscape classification standards, patch area statistical distribution index, patch type total area index, patch density (PD), and edge index (ED) of different regions, the differences in regional ecological environment are deeply analyzed. The results show that GIS technology has a strong ability in regional planning and can provide detailed geographic information analysis data, providing a scientific basis for the green development model planning of landscape ecology, especially in the balanced development of regional economy, social progress, and ecological protection. This demonstrates the scientific validity and practical applicability of GIS methods, providing significant guidance for urban planning and land use.
