Abstract: Taking Yecheng County in Xinjiang as an example,the land space development was simulated as two processes of ecological protection and land development,and the minimum cumulative resistance model and spatial analysis method were used to construct the Yecheng County land space development suitability evaluation system. The results showed that the total area of Yecheng County suitable for land development was 27 359.86 km2, and the total area suitable for ecological protection was 968.84 km2,showing a centrally divergent and zonal distribution pattern on the whole; Yecheng County was divided into ecological protection zones(81.79%), protected development zones(14.79%), development protected zones(2.78%) and development and construction zones(0.64%). Using the minimum cumulative resistance model to evaluate the suitability of land and space development could be closer to the objective reality of arid counties. The ecological environment in arid areas was fragile, and the development of land space had a great impact on the ecological environment. In the future, it should be continued to promote the construction of ecological civilization, improve the quality of land space development, implement cultivated land protection and land improvement,strengthen regional ecological environment protection and restoration, continuously optimize development patterns,promote suitability evaluation, and adapt the functions of suitable areas to the planning and construction.

Key words: ecological priority, arid counties, land and space development, suitability evaluation, Yecheng County
