Abstract

In this study, an entropy theory based technique for order preference by similarity to an ideal solution (Entropy-TOPSIS) method is proposed for assessing soil conservation benefits in Qijiachuan demonstration area of Yellow River basin. Entropy-TOPSIS method integrating entropy theory into TOPSIS model can deal with qualitative and quantitative data during assessment processes. The developed method is then applied to soil conservation assessment in Qijiachuan demonstration area. Soil conserved of different measures in different periods has been calculated. Results indicate that soil conserved in period 3 (2028-2037) ranks the first due to the high vegetation coverage. Soil conserved of cellar, gully head protection and check dam would decrease from period 1 (2008-2017) to period 3 due to the reduced function after years of silting up. Thus, it is necessary to take good maintenance measures to promote function recovery of gully head control measures.
