[Methed] Firstly, the suitability of construction land in the center of Datong City was assessed; afterwards, according to the urban scale and spatial expansion mode in target years in the General Land Use Planning for Datong City （2006 -2020）, the spatial layout of new- ly-increased urban land and flexible construction land was carried out to determine the development boundary of Datong City in 2020. [ Result] In the evaluation area of Datong City, the most suitable construction land had an area of only 66.18 hm2, accounting for 10.40% of total area of evalu- ation region; the area of more suitable construction land was 117.51 hm2 and make up 18.47% of total area; moderately suitable land covered an area of 149.49 hm2, which took up 23.49% of total area; the area of unsuitable construction land （89.31 hm2 ） only made up 14.04% of total area. In the newly-increased urban construction land, the area of the most suitable and more suitable land accounted for 73.58%, while there was no un- suitable land. Meanwhile, in flexible construction land, the area of the most suitable and more suitable land made up 66.85%. In a word, the spa- tial layout of urban land was reasonable in Datong City. [Conclusion] The research could provide theoretical references for the spatial expansion and layout of urban land.展开更多
