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.
