中文摘要:研究区怒江州泸水县地处横断山脉南端的滇西纵谷区,地势北高南低,地形大致以“一江两山”为主体,东部碧罗雪山与西部高黎贡山夹神秘而汹涌的怒江由北向南纵贯全境,境内东西两大山脉纵横交错,高峰林立。境内雄奇险秀的峡谷山川,是“三江并流”世界自然遗产和中国香格里拉生态旅游区的重要组成部分。研究区最高海拔4 161.6 m,最低海拔738 m,相对高差3 423.6 m;晚新生代以来,由于地壳的持续抬升,以及特殊的气候环境,形成了典型的“V”字型高山峡谷地貌景观。不仅如此,其特殊的地理环境还造就了许多独特的地质遗迹,主要以峡谷及河流、雪山及高山湖泊、典型构造剖面、重要化石产地、洞穴类等为主要类型。泸水县境内风景优美、资源丰富,具有很大的旅游开发潜力。结合基础地质调查,科学合理的对这一片区域进行开发利用,不仅符合生态文明建设的宗旨,对促进当地经济的发展和人民生活水平的提高具有很大的帮助。

Treasures in the grand canyon - geological relics of Lushui county, Nujiang river state
Abstract:The study area, Lushui county of the Nujiang state, is located at the longitudinal valley region of the west Yunnan Province at the southern end of the Hengduanshan mountain range, the elevation of which is north higher than south in topography. The landform of the study area mainly consists of one river that is mysterious and turbulent Nujiang river trending nearly NS, and two mountains that is Biluoxueshan mountain to the east and Gaoligongshan mountain to the west respectively. The two crisscross and peak-standing mountains are divided by the Nujiang river that is in between. The spectacular canyons and mountain ranges in the study area are the most important component of the ‘Three Rivers Flow Together’ world natural heritage and Xianggelila ecological tourism zone in China. The highest altitude in the study area is 4161.6 meters, the lowest altitude is 738 meters, between of which the relative height difference is 3423.6 meters. The typical ‘V’ type mountain range and canyon landscape are formed because of the uplift of the crust, as well as the special climate environment since the late Cenozoic. Moreover, its special geographical environment also create many unique geological relics, which mainly include canyons and rivers, snow mountains and top mountain lakes, typical structural sections, the important fossil origins and karst caves and so on. There is beautiful scenery, rich resources, with great tourism development potential in the Lushui county, Nujiang river state. Combined with basic geological survey, scientific and reasonable development and utilization of this area is not only in line with the purpose of ecological civilization construction, but also of great help to promote the development of local economy and the improvement of people"s living standards.
