[Objective]The simulation and analysis of the change of land use and ecological service value in the rapid urbanization area can provide a reference for the scientific land use of land spatial planning in A-wen integration area. [Methods] ESV estimation method, CA_ MCE_ Markov model, contribution calculation and analysis were used to examine the impact of land use change in the A-wen City on the value of ecological services from 2010 to 2030. [Results](1)From 2010 to 2030, grassland and unused land were transferred to other land types, and cultivated land, garden land, forest land and construction land were expanded significantly. ESV increased by 12.962 billion yuan, showing the distribution characteristics of high in the north, low in the south and low in the west. Hydrological regulation was the main part of ESV, and the conversion of water area was the main factor affecting the increase and decrease of ESV.(2)The high value area of ESV was located in northern mountainous area. The low value area was located in western mountainous area and oasis plain in the south. The cold spot area of ESV loss was located in the north of Tianshan ecological conservation area and the middle of urban-rural development coordination area, while the ESV value-added hot spot areas were located in the north of Tianshan ecological conservation area, the south of urban-rural development coordination area and the south of pastoral oasis conservation area.(3)From 2020 to 2030, the ESV value-added area will concentrated in Aksu River Basin. The continuation of development trend will lead to negative growth of ESV in urban and rural development coordination area and pastoral oasis conservation area. [Conclusion] Under the precondition of water resource constraint, afforestation of wasteland, protection of water body and forest and grass land, strict control of urban construction land and cultivated land growth, and guidance of internal structure optimization are the effective measures to seek positive gain of ESV and build a strong ecological security barrier at the southern foot of Tianshan Mountain.
