A study of evaluation of resources and environment carrying capacity of Qixingguan District in Bijie City, Wumeng Mountain, Guizhou Province

Soutliwest karst area is an important eco-sensitive area in China, where the regional physical and geographical conditions are complex and the eco-geological environment is relatively fragile. The extensive mode of resource development has agravated the damage to the eco-geological environment, resulting in the relatively backward development of regional economy and society. Exploring the coordinated development of resources and environment in such an area is the only way to promote regional sustainable development. In this study, the authors chose Qixingguan District of Bijie City in a cluster of poverty-stricken areas in Wumeng Mountain as an evaluation pilot. To ascertain the status quo of regional geological resources and environment, the authors explored and constructed the evaluation index system of carrying capacity of geological resources and environment suitable for typical areas of Wumeng Mountain. Som conclusions have been reached:(1) The carrying capacity of geological resources in Qixingguan District is generally strong, but its spatial distribution is uneven.(2) The carrying capacity of the soil and water environment in this area is generally high, but the carrying capacity of the soil and water environment in Qilngga District, Yachi Town and Qingshuipu Town is low due to the existence of certain soil and water environmental pollution. (3) The carrying capacity of regional geological safety is mainly medium to strong.Zhuchang and Xiaoba areas in the suburbs of urban areas have strong carrying capacity of regional geological safety, which are favorable areas for urban planning and engineering construction. The evaluation results can provide basic geological basis for regional territorial spatial planning and delimitation of "three districts and three lines".
