Abstract—Ecological sensitivity analysis is an important basis of city planning. To optimize the land use layout and promote the ecological construction and environmental protection, remote sensing technology and geographic information system technology are used to construct the index system of ecological sensitivity analysis innovatively from five layers of nature. Then the comprehensive analysis and evaluation of the study area are carried out with the spatial distribution of ecological sensitivity. The results show that the ecological sensitivity of the study area is high on the whole. Extremely high and highly sensitive areas account for 36.08% of the research region, mildly sensitive and moderately sensitive are as account for 52.20%, and non-sensitive area is the smallest, only account for 11.72%. Existing built-up lands are mainly distributed in the moderately, mildly and non-sensitive areas. However, there are about 20% of the built-up lands distributed in the extremely high or highly sensitive areas. Overall, the consideration of the ecological sensitivity of new development lands is insufficient. In the later urban expansion, the land development of the extremely high and highly sensitive areas should be strictly limited. Furthermore, ecological restoration should be performed at the same time or in the near future.

Index Terms—Ecological sensitivity, remote sensing, geographic information system, spatial distribution, land development.
