It is the intersection of the Qinghai-Tibet Plateau, the Loess Plateau, and the Qinba Mountains, with a total area of approximately 44,000 square kilometers. Its geological structure is the joint of the folds of the West Qinling and East Kunlun, which is part of the eastern edge of the Qinghai-Tibet Plateau. The high altitude, low temperature, and high precipitation have formed the characteristics of high-humidity and humid climate: four seasons are not clear, and the weather is cold and windy. The annual temperature difference is small, the daily difference is large, and the vertical climate difference is significant. The annual sunshine number is mostly at 2100— Between 2550 hours, the average annual temperature is 1.1-2.6°C, the frost-free period is about 100 days in the northeast, and only 15-19 days in the southwest; the annual precipitation is between 450-800mm, mainly in late August to September.
