- Abstract:
-
Evaluating mountainous urban construction land suitability is the crucial foundational support to implementing the strategy of ‘building urban projects on mountain land’ in Yunnan Province. The factors in land suitability evaluation are generally summed up into special factors and element factors. The special factors were divided into slope (steep slope), geological disasters, earthquake fault zone, important mineral overlaying, basic farmland protection, eco-environmental security, and natural and cultural heritage protection based on the reality of Yunnan. Then we gave a separate analysis on the effects of the seven factors on mountainous urban construction land suitability and its rigid restrictive function. Finally, the land suitable for urban construction in mountainous areas of Yunnan Province (or hereinafter referred to as ‘land suitable for construction in mountainous areas’) was defined as the gentle slope area with gradient ranging from 8° to 25°, and that is located outside of zone with high risk of geological disasters, zone with 500 m of seismo-fault, zone of important mineral resources overlaid with construction projects, zone for basic farmland protection, zone for eco-environmental risk control and zone for natural and cultural heritage protection. The result could provide a foundational support to implementing mountainous urban construction land suitability evaluation and promoting mountainous urban construction in Yunnan Province or the similar regions.
