Abstract:: In this paper, with GIS technology, using maximum of the factor-overlay method, ecological sensitivity and its distribution are thoroughly analyzed by selecting regionally representative factors according to environmental background in Xuzhou. Five classes of ecological sensitivity ranging from extreme to low were generated:extreme sensitivity zone, high sensitivity zone, moderate sensitivity zone, low sensitivity zone and non-sensitivity zone, in order to provide valuable references for the development and planning. The results indicate that:17.29% of the study area was upper moderate ecological sensitivity zone, 9.85% of the study area was moderate ecological sensitivity zone and under moderate ecological sensitivity zone accounts for 72.85%, which shows that ecological sensitivity in Xuzhou is generally low.
