Abstract: Ecological sensitivity analysis is of great significance to formulating regional environmental policy and development plan and carrying out environmental management and protection effectively. Gui’an New Area, Guiyang , Guizhou Province is a state-level new area. A timely assessment on its eco-environment is of great significance to its green development. Six eco-environmental factors of soil erosion, vegetation, water conservation, lithology, water system and slope are selected for ecological sensitivity analysis. By employing the weighted superposition method and single factor analysis method, the spatial distribution of ecological sensitivity of the new area is obtained with ArcGIS technology. Furthermore, the spatial distribution of comprehensive ecological sensitivity of Gui’an New Area is obtained by the comprehensive analysis method. According to the analysis results, the five levels distribution for ecological sensitive zones (extremely sensitivity, highly sensitivity, moderate sensitivity, mild sensitivity and insensitivity) is determined. The corresponding development and protection suggestions for different ecological sensitive zones are put forward to provide reference for decision making.
