As the early stage of land planning and resource management, the evaluation of land use suitability provides a scientific basis for rational and effective use of limited land resources. This paper takes Chang’an District of Xi’an City, Shaanxi Province as an example, and the key of ecosystem services was taking as an important factor for developing the evaluation system of the suitability of construction land.The results show that the area of the highly suitable construction land in Chang’an District is 766.03km 2 , accounting for 48.18% of the total study area. The forbidden construction area is 585.00km 2 , accounting for 36.79%. Moderately suitable and low suitable construction regions account for 15.03%. The suitable construction regions are concentrated in the northern part of Chang’an District, which is suitable for large-scale development of cities and towns. The moderately and low suitable regions are mainly distributed along the northern foot of the Qinling Mountains. The Qinling Mountains have importance level of ecosystem services, which mostly are forbidden construction regions. The research results will provide a scientific reference for regional construction and development.
