【摘要】:關(guān)中盆地是渭河及其主要支流匯集歸入黃河的區(qū)域,因而有渭河沖積平原之稱。盆地之東為函谷關(guān),西為散關(guān)、南為武關(guān)、北為蕭關(guān),四關(guān)挾持,故又有關(guān)中平原之稱。關(guān)中盆地西起寶雞,東迄黃河,南依秦嶺,北傍渭北低山,東西長約400km,南北寬30~80km,面積約3400km2,整體似半個彎月橫亙于陜西省中部。關(guān)中盆地發(fā)育在鄂爾多斯臺地與秦嶺褶皺帶交界部位,地處中國重要的大地構(gòu)造分界位置上。關(guān)中盆地作為中國大陸典型的新生代裂陷盆地,新構(gòu)造活動強(qiáng)烈、表象明顯,也是我國新構(gòu)造運(yùn)動研究水平較高的地區(qū)之一,在演化歷程上具明顯的周期性,新構(gòu)造活動與地貌、水系、第四紀(jì)沉積、溫泉、地震和地質(zhì)災(zāi)害的空間分布及其變化具有良好的一致性。由于該地區(qū)地處四個不同構(gòu)造單元的交接過渡部位,加之又受到整個汾渭裂陷帶整體活動的影響,地形地貌復(fù)雜,河流地貌與溫泉發(fā)育,造就了該地區(qū)豐富的地質(zhì)遺跡資源。在經(jīng)歷了地質(zhì)遺跡開發(fā)保護(hù)及旅游業(yè)發(fā)展之后,該地區(qū)形成了一系列的以地質(zhì)遺跡為主體的旅游景區(qū),尤其是以秦嶺終南山世界地質(zhì)公園為主的各類地質(zhì)公園的開發(fā),促進(jìn)了該地區(qū)地質(zhì)遺跡資源的開發(fā)利用。本文依托《關(guān)中盆地1∶10萬水文地質(zhì)工程地質(zhì)調(diào)查》項(xiàng)目,通過對關(guān)中盆地區(qū)域內(nèi)地質(zhì)遺跡旅游資源的實(shí)地調(diào)查與資料收集,建立地質(zhì)遺跡評價模型,對區(qū)域內(nèi)地質(zhì)遺跡進(jìn)行科學(xué)價值和旅游價值的評價,同時從區(qū)域地質(zhì)和新構(gòu)造運(yùn)動及地貌等方面對該地區(qū)地質(zhì)遺跡形成機(jī)理進(jìn)行分析研究,最終探討關(guān)中盆地地質(zhì)遺跡資源的開發(fā)、保護(hù)與可持續(xù)利用,提出關(guān)中盆地地質(zhì)遺跡景觀開發(fā)及保護(hù)的建議和對策。
[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.
