By taking Baiji City of Shaanxi Province as a research object,land sensibility and its spatial distribution are studied in views of the sensitivities to soil erosion，bio-diversity protection,and geology disaster under support of GIS technologies.Single and comprehensive element sensitivity assessment is used in the study. Results show that regional differences of land eco-environmental sensitivity in the city are comparatively obvious. The proportion of slightly sensitive area to the total area is 62.1>;the moderately sensitive area acco unt s for 37>;and highly sensitive area shares the smallest proportion,only accounting for 0. 9>.By combining with the result of ecoenvironmental sensitivity assessment,countermeasures for ecoenvironmental construction and protection of each of the areas are proposed and a basis for government making land policy is provided.
