As one of the first 10 national park system pilot projects established in China, the Qilian Mountain National Park system pilot project is divided into two areas: Qinghai and Gansu. The Qinghai area covers a total area of 15800 square kilometers, involving 17 towns and 60 villages in 4 counties and cities, including Menyuan, Qilian, Tianjun, Delingha, and other protected areas such as the Qilian Mountain Provincial Nature Reserve, Xianmi National Forest Park, and Heiheyuan National Wetland Park. Qilian Mountain National Park is the area with the highest ecological value, authenticity, and integrity in China. It is not only a pilot area for ecological civilization system reform, a water source conservation area, and a biodiversity protection demonstration area, but also a model area for ecosystem restoration. Mountains are connected to mountains, valleys are connected to ditches, and ravines are crisscrossing and winding. Entering the Qilian Mountains, one comes to the world of mountains. In the vast valley with abundant grass, you can see the flocks of sheep floating like white clouds in the mountains; On the snowy mountains, one can witness the wonders of June's snowfall in Qilian; Crossing through the forest and sea, the sound of Lin Haitao is in my ears... The Qilian Mountains, an important ecological safety barrier in western China, have suffered serious damage to local ecology. In September 2017, China officially launched a pilot project for the Qilian Mountain National Park system, raising the protection of the Qilian Mountain ecology to the entire national level. As a procuratorial organ in the pilot area of the national park system, in recent years, the procuratorial organs of Qinghai Province have been able to perform their procuratorial functions in accordance with the law, fully serving and ensuring the construction of the Qilian Mountain National Park system, continuously deepening the ecological protection of the Qinghai Tibet Plateau, and cherishing the "greatness of the country". They have placed their national sentiments in the mountains and rivers of the plateau and in the performance of procuratorial duties. Strike and protect equally, and safeguard the biodiversity of the plateau. The Qilian Mountain National Park has a unique ecosystem, which is one of the areas with the most abundant, unique, and concentrated biodiversity in high-altitude areas of the same latitude. It is also an important corridor for the world's alpine germplasm resource pool and wildlife migration. How to leverage procuratorial power to protect the beauty of biodiversity in Qilian Mountains? In recent years, the procuratorial organs of Qinghai Province have actively promoted the effective connection between procuratorial public interest litigation and administrative law enforcement. In handling cases, they have collaborated with administrative authorities to perform their duties in accordance with the law through communication and consultation, public hearings, and procuratorial suggestions, and handled a number of typical cases. Get off the car and see if such a large tree is involved in illegal logging? "On an evening in September 2018, a police officer from the Qinghai Provincial Procuratorate discovered multiple people cutting down trees on the roadside while returning from their official duties. After investigation, one of them turned out to be a national key protected ancient tree, Xiaoye Poplar, with an age of over 200 years. Poplar has a long growth cycle and can conserve water sources, prevent wind and fix sand, playing an important role in the ecological protection of the Qilian Mountains. However, due to the lack of supervision by the administrative department and the lack of environmental awareness among the local people, the small leaved poplar was once arbitrarily cut down. In response, the Qilian County Procuratorate promptly issued procuratorial suggestions, urging relevant administrative departments to strengthen supervision and legally control the indiscriminate logging of small leaved poplar, which not only recovered ecological losses but also raised the public's awareness of ancient tree protection. With the comprehensive implementation of the procuratorial public interest litigation system, the protection of small leaf poplar has also upgraded from the initial prohibition of logging to the protection of species
