Abstract: To explore the influence of forestry ecological project on the local environment, the landscape evolution characteristics of Dengkou County during 2000 and 2014 were studied using multifarious landscape analysis methods. On the basis, the landscape pattern of Dengkou County in 2021 was simulated using CA/Markov model under the following conditions: either with or without the landscape transfer probabilities caused by forestry ecological project. Then, the transfer characteristics of the barycenter of landscape types under each simulation condition were analyzed. It was shown that during the 14 years studied, the area of water, forestry land and construction land increased obviously, while the area of desert decreased apparently. Forestry land, desert, construction land and water had higher dynamic degrees. The landscape dynamic degrees in the border area of different landscape types were relatively high. The barycenter of water and forestry migrated to the south-west of the county and the barycenter of desert migrated back to the hinterland of the Ulanbuh Desert markedly. The simulation results with the landscape transfer probabilities caused by forestry ecological project indicated that the landscape pattern of Dengkou County would show an ecofriendly trend of evolution, while the landscape would deteriorate without the landscape transfer probabilities caused by forestry ecological project. The study results indicated that the forestry ecological project played key role in environment improvement in Dengkou County.

Key words: forestry ecological project, landscape pattern evolution, barycenter migration, Dengkou County, CA/Markov model
