Study on Ecological Sensitivity Evaluation of Pingxiang City

As an important trade port in inland China,Pingxiang City can provide scientific basis for local sustainable development by understanding its ecologically sensitive characteristics.This paper selected the main ecological sensitivity factors(elevation,slope,aspect,nomralized difference vegetation index,water area distance)for GIS overlay analysis,and the overlay analysis results were divided into five levels: highly sensitive,highly sensitive,moderately sensitive,low sensitive and low sensitive.The research results showed that the ecological quality of Pingxiang City was good,and there were small clusters of high sensitivity in spatial distribution.The low sensitivity area was 54.72 km²(8.48%),the low sensitivity area was 156.09 km²(24.18%),the medium sensitivity area was 223.33 km²(34.59%),the high sensitivity area was 139.73 km²(21.64%),and the high sensitivity area was 71.73 km²(11.11%).It is suggested to establish ecological protection buffer zone and key ecological protection zone in the southwest of Pingxiang City to connect the ecological and economic development space.
