Optimized territorial development and intensive land use constitute an important part of ecological civilization construction. Ecological sensitivity analysis provides an important basis for optimizing territorial spatial planning and land-use development, while also contributing to the sustainable development of the regional ecological environment. With the support of GIS technology, this study selected five ecological sensitivity factors, namely elevation, slope, water bodies, NDVI, and land-use type. The Analytic Hierarchy Process (AHP) was employed to determine factor weights, and spatial overlay analysis was used to quantitatively assess ecological sensitivity. The results were classified into four categories: highly sensitive, moderately sensitive, low-sensitive, and non-sensitive areas. On this basis, a comprehensive analysis of each ecological sensitivity zone was conducted, yielding both single-factor and integrated ecological sensitivity assessment results for Baoji City. Finally, corresponding suggestions for zoned protection and development were proposed for the construction of the Guanzhong Plain Urban Agglomeration.
