Abstract
The evaluation of ecological land use efficiency emphasized the protection of regional ecosystem structure and function and enhanced the ecological environment supporting capacity of social and economic development. Thus, the minimum cumulative resistance model (MCR) was adopted to simulate the spatial expansion process of important ecological land by taking important ecological land as the “source” and the land cover type, distance from the road, and distance from the residential area as the “resistance factors” to generate the resistance surface. It was proved through analysis that the method had strong operability, and its further promotion and application in the field of urban efficiency evaluation needed continuous research and improvement of scholars. The results showed that the total area of important ecological land was 9879 km2, accounting for about 60% of the total urban area; the suitable scale of ecological land was 12,417 km2, accounting for about 76% of the total urban area.
