This study identified the ecological restoration approaches on planted forest, natural forest, and natural grassland protection during 2000\u20132022 based on a developed object-oriented continuous change detection and classification (OO-CCDC) method. Taking the Loess hilly region in the southern Ningxia Hui Autonomous Region, China as a case study, we assessed the ecological effects after protecting forest or grassland automatically and continuously by highlighting the location and change time of positive or negative effects. The results showed that the accuracy of ecological restoration approaches extraction was 90.73%, and the accuracies of the ecological restoration effects were 86.1% in time and 84.4% in space. A detailed evaluation from 2000 to 2022 demonstrated that positive effects peaked in 2013 (1262.69 km2), while the highest negative effects were observed in 2017 (54.54 km2). In total, 94.39% of the planted forests, 99.56% of the natural forest protection, and 62.36% of the grassland protection were in a stable pattern, and 35.37% of the natural grassland displayed positive effects, indicating a proactive role for forest management and ecological restoration in an ecologically fragile region. The negative effects accounted for a small proportion, only 2.41% of the planted forests concentrated in Pengyang County and 2.62% of the natural grassland protection mainly distributed around the farmland in the central-eastern part of the study area. By highlighting regions with positive effects as acceptable references and regions with negative effects as essential conservation objects, this study provides valuable insights for evaluating the effectiveness of the integrated ecological restoration pattern and determining the configuration of ecological restoration measures.<\/jats:p>","DOI":"10.3390\/rs15164023","type":"journal-article","created":{"date-parts":[[2023,8,14]],"date-time":"2023-08-14T10:40:31Z","timestamp":1692009631000},"page":"4023","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Identification of Ecological Restoration Approaches and Effects Based on the OO-CCDC Algorithm in an Ecologically Fragile Region"],"prefix":"10.3390","volume":"15","author":[{"given":"Caiyong","family":"Wei","sequence":"first","affiliation":[{"name":"School of Information Engineering, China University of Geosciences, Beijing 100083, China"},{"name":"Ningxia Institute of Remote Sensing Survey, Yinchuan 750021, China"}]},{"given":"Xiaojing","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Information Engineering, China University of Geosciences, Beijing 100083, China"}]},{"given":"Lingwen","family":"Tian","sequence":"additional","affiliation":[{"name":"School of Information Engineering, China University of Geosciences, Beijing 100083, China"}]},{"given":"Qin","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Information Engineering, China University of Geosciences, Beijing 100083, China"}]},{"given":"Bowen","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Information Engineering, China University of Geosciences, Beijing 100083, China"}]},{"given":"Wenlong","family":"Wang","sequence":"additional","affiliation":[{"name":"Ningxia Institute of Remote Sensing Survey, Yinchuan 750021, China"}]},{"given":"Dawei","family":"Ma","sequence":"additional","affiliation":[{"name":"Ningxia Institute of Remote Sensing Survey, Yinchuan 750021, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1338-0132","authenticated-orcid":false,"given":"Yuanyuan","family":"Meng","sequence":"additional","affiliation":[{"name":"Institute of Ecology, College of Urban and Environmental Sciences and Key Laboratory for Earth Surface Processes, Peking University, Beijing 100871, China"}]},{"given":"Xiangnan","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information Engineering, China University of Geosciences, Beijing 100083, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"180","DOI":"10.1111\/emr.12229","article-title":"Ecological Restoration in Urban Environments in New Zealand","volume":"17","author":"Clarkson","year":"2016","journal-title":"Ecol.
