[Objective] Selecting Chan-Ba ecological district(CBE) of Xi'an City, Shaanxi Province as a typical urban area in the north of Qinling Mountains, the study aims to provide support for the regional urban development and ecological construction based on the analysis of the sustainability of new area development from two aspects, i.e. landscape pattern and the value of ecosystem services.[Methods] Using on the remote sensing data, the study quantitatively analyzed land use and landscape change, and detected changes in landscape-scale ecosystem and in values of ecosystem services in newly developing urban areas.[Results] (1) In period from 2004 to 2014, the conversion of rural area to urban area is obvious, the proportion of agricultural land reduced significantly while construction land increased by 88.2%, and ecological landscape by more than 201.5%, meaning the significant increase of region's "ecological content".(2) The significant changes occurred in the ecological service value in farmland, vegetated land and wet land, and nearly 65% of farmland ecosystem services value were lost. In 2014, more than 85% of the region's ecological functions and services were from the vegetated land and water.[Conclusion] The changes of ecological land was dynamic in past decade in CBE, and the value of ecological service in urban area increased significantly, showing a great improvement of the environment during the urbanization. This means that the policy of ecological construction is good for the construction and development of regional ecosystems.
