This study executed a decadal monitoring of post-seismic landslide activities all over the region by investigating landslide vegetation recovery rate (VRR) with Landsat images and a (nearly) complete landslide inventory. Thirty thousand landslides that were larger than nine pixels were chosen for VRR analysis, to reduce the influence of mixed pixels and support detailed investigation within landslides. The study indicates that about 60% of landslide vegetation gets close to the pre-earthquake level in ten years and is expected to recover to the pre-earthquake level within 20 years. The vegetation recovery is significantly influenced by topographic factors, especially elevation and slope, while it is barely related to the distance to epicenter, fault ruptures, and rivers. This study checked and improved the knowledge of vegetation recovery and landslide stability in the area, based on a detailed investigation.<\/jats:p>","DOI":"10.3390\/s21155243","type":"journal-article","created":{"date-parts":[[2021,8,4]],"date-time":"2021-08-04T02:16:07Z","timestamp":1628043367000},"page":"5243","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Discovering Vegetation Recovery and Landslide Activities in the Wenchuan Earthquake Area with Landsat Imagery"],"prefix":"10.3390","volume":"21","author":[{"given":"Cheng","family":"Zhong","sequence":"first","affiliation":[{"name":"Three Gorges Research Center for Geo-hazard, Ministry of Education, China University of Geosciences, Wuhan 430074, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5229-8158","authenticated-orcid":false,"given":"Chang","family":"Li","sequence":"additional","affiliation":[{"name":"Three Gorges Research Center for Geo-hazard, Ministry of Education, China University of Geosciences, Wuhan 430074, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9599-855X","authenticated-orcid":false,"given":"Peng","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Earth and Ocean Sciences, University of North Carolina, Wilmington, NC 28403, USA"},{"name":"Department of Geography, University of South Carolina, Columbia, SC 29208, USA"}]},{"given":"Hui","family":"Li","sequence":"additional","affiliation":[{"name":"School of Earth Sciences, China University of Geosciences, Wuhan 430074, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1783","DOI":"10.1007\/s10346-017-0824-9","article-title":"Hazard assessment of debris flows in the Wenchuan earthquake-stricken area South West China","volume":"14","author":"Chang","year":"2017","journal-title":"Landslides"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/j.enggeo.2007.12.001","article-title":"Influence of typhoons and earthquakes on rainfall-induced landslides and suspended sediments discharge","volume":"97","author":"Lin","year":"2008","journal-title":"Eng.
