It is of great significance to promptly and accurately grasp the information on dynamic temporal and spatial changes in abandoned farmland to ensure national food security and the sustainable use of cultivated land. Luquan District in Hebei, China was selected as the research area based on multispectral images from Sentinel-2A, Landsat-7, and Landsat-8 combined with methods of random forest (RF) classification and vegetation index change detection. Rules for the identification of abandoned farmland were also developed, and remote sensing monitoring of the abandonment status of the cultivated land was also carried out in the study area. We also obtained the spatial distribution of abandoned and reclaimed farmland and analysed the frequency of farmland abandonment. The results show that the overall accuracy of the land-use time-series map ranged from 90.20% to 96.92% for the study period of 2010\u20132020. The average rate of farmland abandonment in the study area was 10.62%, with the lowest rate (5.83%) in 2020 and the highest (14.09%) in 2012. From 2011 to 2020, the maximum farmland abandonment area was 3906.02 hm2, and the minimum area was 1618.74 hm2. The farmland abandonment area showed a trend of first increasing and then decreasing. From 2012 to 2020, the maximum area of reclaimed farmland was 291.49 hm2, and the highest rate of reclamation was 14.26%. The overall reclamation rate was low. The abandonment frequency of most of the abandoned farmland was 1\u20133 years, covering an area of 8193.73 hm2, which comprised 79% of the total area of abandoned farmland. The frequency of abandonment was inversely proportional to the area of abandoned farmland. Farmland abandonment mainly occurred in hilly areas. We expect that our results can provide case studies for long time series in farmland abandonment research and can provide a reference for studying the driving factors, risk assessment, and policymaking with respect to abandoned farmland.<\/jats:p>","DOI":"10.3390\/rs13132549","type":"journal-article","created":{"date-parts":[[2021,6,29]],"date-time":"2021-06-29T22:39:43Z","timestamp":1625006383000},"page":"2549","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Analysis of the Spatial and Temporal Pattern of Changes in Abandoned Farmland Based on Long Time Series of Remote Sensing Data"],"prefix":"10.3390","volume":"13","author":[{"given":"Zhonghui","family":"Wei","sequence":"first","affiliation":[{"name":"Beijing Research Center for Information Technology in Agriculture, Beijing 100097, China"},{"name":"School of Surveying and Land Information Engineering, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"given":"Xiaohe","family":"Gu","sequence":"additional","affiliation":[{"name":"Beijing Research Center for Information Technology in Agriculture, Beijing 100097, China"}]},{"given":"Qian","family":"Sun","sequence":"additional","affiliation":[{"name":"Beijing Research Center for Information Technology in Agriculture, Beijing 100097, China"},{"name":"College of Information and Electrical Engineering, China Agricultural University, Beijing 100083, China"}]},{"given":"Xueqian","family":"Hu","sequence":"additional","affiliation":[{"name":"Beijing Research Center for Information Technology in Agriculture, Beijing 100097, China"},{"name":"College of Geodesy and Geomatics, Shandong University of Science and Technology, Qingdao 266590, China"}]},{"given":"Yunbing","family":"Gao","sequence":"additional","affiliation":[{"name":"Beijing Research Center for Information Technology in Agriculture, Beijing 100097, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,29]]},"reference":[{"key":"ref_1","first-page":"4","article-title":"Influences of labor emigration from agriculture on the production abandonment of cultivated land in ecological sensitive areas","volume":"24","author":"Tian","year":"2010","journal-title":"China Land Sci."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"569","DOI":"10.1016\/j.landusepol.2016.10.005","article-title":"Impact of rural out-migration on arable land use intensity: Evidence from mountain areas in Guangdong, China","volume":"59","author":"Liu","year":"2016","journal-title":"Land Use Pol."},{"key":"ref_3","first-page":"370","article-title":"Progress and prospect on farmland abandonment","volume":"71","author":"Li","year":"2016","journal-title":"Acta Geogr.
