Abstract Ecological environment of Kenli County was quantitatively evaluated by using CBERS multi-spectral image and applying quantitative remote sensing techniques. Indices of land degradation, vegetation, water density and human activity, which reflect conditions of ecological environment were extracted. Overall ecological environment of Kenli was relatively poor. Areas included in excellent and good lands only accounted for 24.64% of the whole county, which mainly distributed in the northeastern forest land and the southwestern and central agricultural land. 44.08% of the whole county belonged to moderate grade, which distributed in the eastern coastal beach and sparsely in the western,central and northeastern agricultural land. The poor and inferior lands accounted for 30.12% of the whole county, which mainly distributed in the central and the northern salt wasteland.
