This study was conducted to solve the environmental problems of Kenli County,based on environmental sensitivity theory.Vegetation cover,groundwater salinity,buried diving depth,soil texture,and physiognomy were selected as environmental sensitivity factors.Supported by GIS technology,each evaluation factor was evaluated,the weights were obtained through expert scoring method,and the environmental sensitivity of each unit was calculated using index-sum method.Results indicated that the extremely sensitive area occupied 37.4% of the total area,the highly sensitive area occupied 25.7%,the moderately sensitive area occupied 26.0%,and the sensitive area occupied 10.9%.From southwest to northeast,the sensitivity degree increased with the Yellow River extending to the Bohai Sea.The results can be a reference to make environmental policies in Kenli County.
