Abstract The purpose of this study is to find the right area as construction land for the new district of Lanzhou City through an appropriate and scientific evaluation on ecological suitability assessment. Method of revised simplex weight overlap (potential-resistance analysis) was employed to make an appropriate and scientific evaluation on ecological suitability assessment of construction land use in the new district of Lanzhou city. The results indicate that the main ecological potential of the new district is the first-class potential, followed by the second-class and the others take a little proportion. The results also indicate that the first-class ecological resistance is mainly distributed in the south area of the new district in general. Furthermore, according to the ecological suitability assessment which is based on the potential-resistance analysis, the first-class ecological suitability zone, about 39 425.91 hm2, occupied 48.92% of the total area of the new district. The third-class ecological suitability zone, about 6 513.2 hm2, is the least area and takes 8.08% of the total area of the new district. With method of potential-resistance analysis, the paper divided four districts corresponding to the ecological suitability, which are concentrating construction zone, massive development area, restricted construction area and forbidden built area. Among all of the four districts, the concentrating construction zone and the massive development area are the ideal choice for construction land use.
