【摘要】：关中盆地是渭河及其主要支流汇集归入黄河的区域,因而有渭河冲积平原之称。盆地之东为函谷关,西为散关、南为武关、北为萧关,四关挟持,故又有关中平原之称。关中盆地西起宝鸡,东迄黄河,南依秦岭,北傍渭北低山,东西长约400km,南北宽30~80km,面积约3400km2,整体似半个弯月横亘于陕西省中部。关中盆地发育在鄂尔多斯台地与秦岭褶皱带交界部位,地处中国重要的大地构造分界位置上。关中盆地作为中国大陆典型的新生代裂陷盆地,新构造活动强烈、表象明显,也是我国新构造运动研究水平较高的地区之一,在演化历程上具明显的周期性,新构造活动与地貌、水系、第四纪沉积、温泉、地震和地质灾害的空间分布及其变化具有良好的一致性。由于该地区地处四个不同构造单元的交接过渡部位,加之又受到整个汾渭裂陷带整体活动的影响,地形地貌复杂,河流地貌与温泉发育,造就了该地区丰富的地质遗迹资源。在经历了地质遗迹开发保护及旅游业发展之后,该地区形成了一系列的以地质遗迹为主体的旅游景区,尤其是以秦岭终南山世界地质公园为主的各类地质公园的开发,促进了该地区地质遗迹资源的开发利用。本文依托《关中盆地1∶10万水文地质工程地质调查》项目,通过对关中盆地区域内地质遗迹旅游资源的实地调查与资料收集,建立地质遗迹评价模型,对区域内地质遗迹进行科学价值和旅游价值的评价,同时从区域地质和新构造运动及地貌等方面对该地区地质遗迹形成机理进行分析研究,最终探讨关中盆地地质遗迹资源的开发、保护与可持续利用,提出关中盆地地质遗迹景观开发及保护的建议和对策。
[Abstract]:The Guanzhong basin is the area where the Weihe River and its main tributaries converge into the Yellow River, so it is called the Weihe River alluvial plain. The east of the basin is Fanguguan, the west is Sanguan, the south is Wanguan, the north is Xiaoguan, and the four customs are hostage, so the central plain is also called. The Guanzhong basin starts from Baoji in the west and reaches the Yellow River in the east, south of the Qinling Mountains in the south and Weibei low mountain in the north, with an east-west length of about 400km, and an area of about 3400km2 across the north and south of the basin. The Guanzhong basin is located at the junction of the Ordos platform and the Qinling fold belt and is located at the important tectonic boundary in China. As a typical Cenozoic rifting basin in the Chinese mainland, the Guanzhong basin has strong neotectonic activity and obvious appearance, and is also one of the areas with high research level of neotectonic movement in China, and has obvious periodicity in the evolution process. There is good consistency between neotectonic activity and spatial distribution and variation of geomorphology, water system, Quaternary sediments, hot springs, earthquakes and geological disasters. Because this area is located at the transition site of four different tectonic units, and is affected by the whole activity of the fen Wei rift belt, the topography and geomorphology are complicated, the river landforms and hot springs are developed, and the rich geological relics resources are formed in this area. After the exploitation and protection of geological relics and the development of tourism, a series of tourist attractions with geological relics as the main body have been formed in this area, especially the development of all kinds of geopark, which is dominated by the world geopark in the Qinling Mountains. It promotes the exploitation and utilization of geological relics resources in this area. Based on the project of "1: 100,000 Hydrogeologic Engineering Geological Survey of Guanzhong Basin", this paper establishes a geological relic evaluation model by field investigation and data collection of geological relics tourism resources in Guanzhong Basin. The scientific value and tourism value of geological relics in the region are evaluated, and the formation mechanism of geological relics in this area is analyzed and studied from the aspects of regional geology, neotectonic movement and geomorphology. Finally, the development, protection and sustainable utilization of geological relics resources in Guanzhong Basin are discussed, and suggestions and countermeasures for exploitation and protection of geological relics landscape in Guanzhong Basin are put forward.
