Method and Application of Land Suitability Assessment in Peri-Urban Areas: A Case Study on Jimei District, Xiamen City

The purpose of this study is to establish an indicator system for assessing land suitability in peri-urban areas so as to promote the sustainable utilization of land resources in the areas between rural and urban areas. Methods and steps employed include firstly dividing Jimei district of Xiamen City into three land-use types, e.g., agricultural land, construction land and ecological land, and secondly selecting appropriate assessment indicators, and thirdly assessing each land-use type based on methods of remote sensing, geographical information system, AHP and expert marking, etc. The results indicate that the areas that suitable for agricultural land, construction land and ecological land in Jimei District respectively account for 11.7%, 15.4% and 1.6% of the total area, which is comparatively in accordance with the actual situation. It is concluded that the indicator system and assessment steps in this paper can be used for other peri-urban areas.
