What are the main characteristic tourism resources in Qinghai-Tibet region (2 points)

1. Tourism resources have distinct regional characteristics: there are many tall mountains on the Qinghai-Tibet Plateau, all above the snow line, standing at the edge and middle of the open plateau and basin, and the average height is incomparable to any other mountain in the world. The peaks are covered with silver all year round, and the glaciers are suspended, forming the most spectacular and unique snowy plateau scenery in the world. 2. Tourism resources are highly concentrated: along the Qinghai-Tibet Railway, due to a series of problems such as traffic bottlenecks, a considerable number of tourism resources are still "hidden in boudoir". For example, the mysterious "forbidden area of life"-Qiangtang Plateau, the majestic Kunlun known as the "backbone of Asia", the charming Hoh Xil and the steep and deep Yarlung Zangbo Grand Canyon, the world's largest canyon. All these tourist resources, with their unique charm, mysterious colors and unrepeatable monopoly, have a strong temptation to the vast number of domestic and foreign tourists and explorers, attracting them to try, want to be there and take a quick look. 3. The diversity of tourism resources is extremely rich: the diversity of tourism resources is a very important factor in evaluating tourist destinations, which directly affects the attraction of tourist destinations to tourists and the length of tourists' stay in this area. The Qinghai-Tibet Plateau is not only complicated in landform types, but also diverse in climate types. Here, you can experience different climates from tropical to polar, from coastal humid areas to inland deserts. In a popular phrase, it is: "wear cotton-padded jacket in the morning, wear yarn in the afternoon, and eat watermelon around the stove." In terms of biological species, there are rare animals such as Tibetan antelope, wild yak and Tibetan wild donkey, and a large number of rare plants grow here, which is called "rare wild animal and plant gene bank". 4. The primacy of tourism resources: Due to the harsh environment, vast territory and sparse population, the impact of human activities on nature is relatively small, and the natural ecosystem of the whole region is basically kept in its original state.
