Study on the Spatial Distribution of Resource-based Urban Land Based on Suitability Evaluation

LEI Shu-xia et al(Beijing Research Center of Urban Systems Engineering,Beijing 100089)  
[Objective] The study aimed at analysing the spatial distribution of urban land based on the suitability evaluation of construction land in resource-based cities.[Method] Firstly,the suitability of construction land in Datong City was assessed;afterwards,according to the urban scale and spatial expansion mode in target year in the General Land Use Planning for Datong City(2006-2020),the spatial layout of newly-increased urban land and flexible construction land was carried out to determine the development boundary of Datong City in 2020.[Result] There was little most suitable construction land in the evaluation area of Datong City,and its area was only 66.18 hm2 which accounted for 10.40% of total area of evaluation region;the area of more suitable construction land was 117.51 hm2 and make up 18.47% of total area;generally suitable land covered an area of 149.49 hm2,which accounted for 23.49% of total area;the area of unsuitable construction land(89.31 hm2) only made up 14.04% of total area.In newly-increased urban construction land,the area of the most suitable and more suitable land accounted for 73.58%,while there was no unsuitable land.Meanwhile,the area of the most suitable and more suitable land made up 66.85% in flexible construction land.In a word,the spatial layout of urban land was reasonable in Datong City.[Construction] The research could provide theoretical bases for the spatial expansion and layout of urban land.
