Abstract

Carrying out the evaluation of land suitability for urban construction in mountainous areas will provide a fundamental basis for building mountainous cities. This study carried out a full evaluation on suitability for urban construction and its suitability grade of each evaluation unit in the mountainous areas of Longchuan County, which is a mountainous border county located in southwest China, based on the latest 1:10000 land-use map produced from the County's Second National Land Survey, against the 12 evaluation indicators, using an approach combining the “Extreme Conditions Method” and “Suitability Index Method”, and with the help of GIS technology. The results show that, the area of mountainous land suitable for construction and no-suitable for construction respectively account 13.01% and 86.99%. And first-class, second and third-class of land suitable for construction should be composited the ratio of about 12:43:45. The suitability evaluation index system and method developed in this paper is applicable for evaluating the construction land suitability in mountainous areas of Yunnan Province, and will provide theoretical and technical support for land policy measures which strengthen the protection of farmland and promote the scientific development of urbanization in Yunnan Province and even similar mountainous areas of the whole China.
