Land eco-efficiency is the key of land resources in loess hilly region. Based on the theory of ecological footprint, and as land use/cover change the breakthrough point in loess hilly area, the ecological carrying capacity analysis method was used to calculate the ecological carrying capacity of Shanghuang experimental area. The results showed that the total ecological carrying capacity in 1982, 2000 and 2010 were 242.47, 750.53, 929.68 hm2, respectively. Meanwhile, the ecological carrying capacity per capita in 1982, 2000 and 2010 were 0.67, 1.47, 1.86 hm2, respectively, the ecological carrying capacity was growing up year by year, which showed that the ecological carrying capacity of the study area steadily increased. The expansion of productive land area and the improvement of the production of ecological land were the causes, in particular, the latter was the key. This study provides a feasible method of quantitative evaluation of land use impact on the ecological environment.
