Carbon sequestration and oxygen production (CSOP) is used to indicate major ecological changes, because they involve complex processes of material circulation and energy flow. Using remote sensing images and weather records, the spatiotemporal variation of CSOP was analyzed in a typical karst region of northwest Guangxi, China, during 2000\u20132010 to determine the effects of the Chinese government\u2019s ecological rehabilitation initiatives implemented in 1999. An increase with substantial annual change and a significant increase (20.94%, p &lt; 0.05) in variation were found from 2000 to 2010. CSOP had a highly clustered distribution in 2010 and was correlated with precipitation and temperature (9.18% and 8.96%, respectively, p &lt; 0.05). CSOP was significantly suppressed by human activities (p &lt; 0.01, r = \u22120.102) but was consistent with the intensity of GTGP (43.80% positive). The power spectrum of CSOP was consistent with that of the gross domestic product. These results indicate that ecological services were improved by rocky desertification control in a typical karst region. The results may provide information to evaluate the efficiency of ecological reconstruction projects.<\/jats:p>","DOI":"10.3390\/rs8020102","type":"journal-article","created":{"date-parts":[[2016,1,28]],"date-time":"2016-01-28T10:31:20Z","timestamp":1453977080000},"page":"102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Spatio-Temporal Variation and Impact Factors for Vegetation Carbon Sequestration and Oxygen Production Based on Rocky Desertification Control in the Karst Region of Southwest China"],"prefix":"10.3390","volume":"8","author":[{"given":"Mingyang","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Agro-ecological Processes in Subtropical Region, Institute of Subtropical Agriculture, Chinese Academy of Sciences, No. 644, Yuanda 2nd Road, Furong District, Changsha 410125, China"},{"name":"Huanjiang Observation and Research Station for Karst Ecosystems, Chinese Academy of Sciences, Huanjiang 547100, China"}]},{"given":"Kelin","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agro-ecological Processes in Subtropical Region, Institute of Subtropical Agriculture, Chinese Academy of Sciences, No. 644, Yuanda 2nd Road, Furong District, Changsha 410125, China"},{"name":"Huanjiang Observation and Research Station for Karst Ecosystems, Chinese Academy of Sciences, Huanjiang 547100, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3976-481X","authenticated-orcid":false,"given":"Huiyu","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Geography Science, Nanjing Normal University, No.1, Wenyuan Road, Xianlin University District, Nanjing 210046, China"},{"name":"Jiangsu Center for Collaborative Innovation in Geographical Information Resource Development and Application, Nanjing 210046, China"}]},{"given":"Jing","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agro-ecological Processes in Subtropical Region, Institute of Subtropical Agriculture, Chinese Academy of Sciences, No. 644, Yuanda 2nd Road, Furong District, Changsha 410125, China"},{"name":"Huanjiang Observation and Research Station for Karst Ecosystems, Chinese Academy of Sciences, Huanjiang 547100, China"}]},{"given":"Chunhua","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agro-ecological Processes in Subtropical Region, Institute of Subtropical Agriculture, Chinese Academy of Sciences, No. 644, Yuanda 2nd Road, Furong District, Changsha 410125, China"},{"name":"Huanjiang Observation and Research Station for Karst Ecosystems, Chinese Academy of Sciences, Huanjiang 547100, China"}]},{"given":"Yuemin","family":"Yue","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agro-ecological Processes in Subtropical Region, Institute of Subtropical Agriculture, Chinese Academy of Sciences, No. 644, Yuanda 2nd Road, Furong District, Changsha 410125, China"},{"name":"Huanjiang Observation and Research Station for Karst Ecosystems, Chinese Academy of Sciences, Huanjiang 547100, China"}]},{"given":"Xiangkun","family":"Qi","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agro-ecological Processes in Subtropical Region, Institute of Subtropical Agriculture, Chinese Academy of Sciences, No. 644, Yuanda 2nd Road, Furong District, Changsha 410125, China"},{"name":"Huanjiang Observation and Research Station for Karst Ecosystems, Chinese Academy of Sciences, Huanjiang 547100, China"}]}],"member":"1968","published-online":{"date-parts":[[2016,1,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"988","DOI":"10.1126\/science.1201609","article-title":"A large and persistent carbon sink in the world\u2019s forests","volume":"333","author":"Pan","year":"2011","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"64","DOI":"10.1016\/j.apgeochem.2011.09.003","article-title":"Carbon export and HCO3\u2212 fate in carbonate catchments: A case study in the karst plateau of southwestern china","volume":"27","author":"Wang","year":"2012","journal-title":"Appl.
