In order to reduce the negative influences of subjective factors, the research aims to build the evaluation model of soil fertility by applying the entropy weight coefficient method. Taking the influence of every factor in the soil fertility into comprehensive consideration, the researcher worked out the weight value of evaluation index and obtained the soil fertility’s comprehensive index value under the guidance of entropy theory. The results prove that entropy weight coefficient method has high accuracy and some subjective factors can be avoided because of the application of entropy. The above sample analysis demonstrates that the evaluation method is simple and feasible and the evaluation results are in conformity with the actual situation.
