In this study, Landsat TM\/OLI were used to track the evolution of snow lines in the snow melting areas of Yushu Tibetan Autonomous Prefecture of the Qinghai-Tibet Plateau (hereinafter referred to as Yushu Prefecture) during the last 30 years. A total of seven extraction schemes were used to classify the rock desert in the ice\u2013snow melting area by remote sensing. Our results show that: (1) The accuracy of the multi-index factor compound analysis and object-oriented classification compound method was the highest. This method can provide a rapid and efficient reference scheme for rock desert extraction in the plateau ice\u2013snow melting area. (2) The combinations of two single methods with higher accuracy can further improve the total accuracy. If a single method with lower accuracy is involved in the multi-method fusion, the accuracy of the method with lower accuracy can be improved. (3) In the past 30 years, there has been a large amount of ice\u2013snow melting in Yushu Prefecture. The ice\u2013snow melting area accounts for 53.78% (1451.04 km2) of the ice\u2013snow area, and the bare rock and bare stone in the rock desert account for 63.77% of the total area of the ice\u2013snow melting area. Bare sand and bare soil area account for 30.27% of the total area of ice and snow melting area.<\/jats:p>","DOI":"10.3390\/rs14030570","type":"journal-article","created":{"date-parts":[[2022,1,25]],"date-time":"2022-01-25T21:07:11Z","timestamp":1643144831000},"page":"570","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Monitoring Rock Desert Formation Caused by Ice\u2013Snow Melting in the Qinghai-Tibet Plateau Using an Optimized Remote Sensing Technique: A Case Study of Yushu Prefecture"],"prefix":"10.3390","volume":"14","author":[{"given":"Wei","family":"Jia","sequence":"first","affiliation":[{"name":"Key Laboratory of Tibetan Plateau Land Surface Processes and Ecological Conservation (Ministry of Education), Xining 810008, China"},{"name":"School of Geographical Science, Qinghai Normal University, Xining 810008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weidong","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Geographical Science, Qinghai Normal University, Xining 810008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peijun","family":"Shi","sequence":"additional","affiliation":[{"name":"Key Laboratory of Tibetan Plateau Land Surface Processes and Ecological Conservation (Ministry of Education), Xining 810008, China"},{"name":"Academy of Plateau Science and Sustainability, Qinghai Normal University, Xining 810008, China"},{"name":"Key Laboratory of Environmental Change and Natural Disaster, Ministry of Education, Beijing Normal University, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing\u2019ai","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Tibetan Plateau Land Surface Processes and Ecological Conservation (Ministry of Education), Xining 810008, China"},{"name":"Key Laboratory of Environmental Change and Natural Disaster, Ministry of Education, Beijing Normal University, Beijing 100875, China"},{"name":"Faculty of Geographical Science, Beijing Normal University, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Su","sequence":"additional","affiliation":[{"name":"School of Geographical Science, Qinghai Normal University, Xining 810008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,25]]},"reference":[{"key":"ref_1","first-page":"259","article-title":"A method for extracting snow line altitude based on MODIS snow product","volume":"39","author":"Bao","year":"2017","journal-title":"J.
