Abstract Zecha Shilin Geopark is located in Luqu County, Gansu Province, where the landform completely preserves the characteristics of alpine karst, with typicality and rarity. In order to reveal its natural scientific value, promote the development of natural resources and landscape protection, through field geological survey, taking Luqu County regional geology as the background, the karst landform types of Zecha Shilin Geopark are introduced, which are mainly plateau stone forest, a line of sky as the highlight, and small karst cave as the auxiliary. Then, the formation mechanism of karst landform in the park is analyzed from four aspects of geological structure, lithology, hydrological climate, and biological factors. It is of certain significance to improve the scientific research of karst series geological relics in high-altitude areas. At the same time, the ecological transformation of alpine karst has a good demonstration effect on the control of karst desertification in South China. Keywords Geopark . Geology and geomorphology .

Introduction The alpine karst of the Qinghai-Tibet Plateau is unique to China, but at present, the research on karst landforms in China is mainly concentrated in the tropical and subtropical areas, especially in the Lunan Stone Forest, while the study on the high-altitude karst landscape of the Qinghai-Tibet Plateau and its eastern adjacent areas is rare. For example, some people have studied the quantitative evolution of karst landform in Shilin County of Yunnan Province based on the area elevation analysis of Strahler and proved that different terrain surfaces with different geomorphic development characteristics have different Strahler values, which has made a certain contribution to the research in this field (Li et al. 2018). In addition, some people have isolated and identified iron

producing carrier bacteria in karst soil of Baise, Guangxi, and selected typical karst landform areas in Baise, Guangxi, for soil sampling, and analyzed the beneficial microbial populations in the area (Wang et al. 2018); and some people have based on the important significance of karst development location and degree for modern urban development and construction. A new understanding of the development law of hidden karst caves was obtained by using the twodimensional micro motion profile detection method to detect the stratigraphic structure in limestone karst area (Huang et al. 2019). There are many scholars who have analyzed the kars
