摘要
西南岩溶地区是中国重要的生态敏感区,生态地质环境较脆弱,在该类地区探索资源与环境的协调发展,是促进区域可持续发展之路。以乌蒙山集中连片扶贫区中的毕节市七星关区为评价试点,查明了区域地质资源环境现状,探索构建了适用于乌蒙山典型地区的地质资源环境承载能力评价指标体系。评价发现:①七星关区地质资源承载能力总体较强,但空间分布不均;②该地区水土环境承载能力总体较高,但七星关区城区、鸭池镇、清水铺镇等局部地区存在一定的水土环境污染,导致水土环境承载能力较低;③区域地质安全承载能力以中等-较强为主,城区近郊的朱昌和小项地区地质安全承载能力强,是进行城市规划和工程建设的有利地区。评价结果可为区域国土空间规划及"三区三线"划定提供地质依据。
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".
