Application of Entropy Weight Coefficient Method in Environmental Assessment of Soil
Environmental assessment of soil has important significance in sustainable utilization for land resourc. Entropy weight coefficient method was applied to built evaluation model of soil environment to be effectively reduced the influences of subjective factors in determine the weight. It was analyzed the influence of every factor in the environmental assessment of soil by entropy, and worked out the weight value of evaluation index and obtained the environmental assessments comprehensive index value. By Compared and analyzed of comprehensive index value, It was obtained that grade of environmental assessment of soil,and the degree of closeness of measured value. It were compared entropy weight coefficient method and the others methods, The results show that entropy weight coefficient method has high accuracy. The above sample analysis demonstrates that the evaluation method is simple and feasible and the evaluation results are in conformity with the actual situation.
