The mechanism, direction and magnitude of climatic and anthropogenic influences on net primary productivity (NPP) of various alpine pastures remain under debate. Here, we simulated the potential productivity (with only climate variables being considered as drivers; NPPP) and actual productivity (based on remote sensing dataset including both climate and anthropogenic drivers; NPPA) from 1993 to 2011. We denoted the difference between NPPP and NPPA as NPPpc to quantify how much forage can be potentially consumed by livestock. The actually consumed productivity (NPPac) by livestock were estimated based on meat production and daily forage consumption per standardized sheep unit. We hypothesized that the gap between NPPpc and NPPac (NPPgap) indicates the direction of vegetation dynamics, restoration or degradation. Our results show that growing season precipitation rather than temperature significantly relates with NPPgap, although warming was significant for the entire study region while precipitation only significantly increased in the northeastern places. On the Northern Tibetan Plateau, 69.05% of available alpine pastures showed a restoration trend with positive NPPgap, and for 58.74% of alpine pastures, stocking rate is suggested to increase in the future because of the positive mean NPPgap and its increasing trend. This study provides a potential framework for regionally regulating grazing management with aims to restore the degraded pastures and sustainable management of the healthy pastures on the Tibetan Plateau.<\/jats:p>","DOI":"10.3390\/rs9020136","type":"journal-article","created":{"date-parts":[[2017,2,7]],"date-time":"2017-02-07T12:08:18Z","timestamp":1486469298000},"page":"136","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Identifying the Relative Contributions of Climate and Grazing to Both Direction and Magnitude of Alpine Grassland Productivity Dynamics from 1993 to 2011 on the Northern Tibetan Plateau"],"prefix":"10.3390","volume":"9","author":[{"given":"Yunfei","family":"Feng","sequence":"first","affiliation":[{"name":"Lhasa Plateau Ecosystem Research Station, Key Laboratory of Ecosystem Network Observation and Modelling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"}]},{"given":"Jianshuang","family":"Wu","sequence":"additional","affiliation":[{"name":"Lhasa Plateau Ecosystem Research Station, Key Laboratory of Ecosystem Network Observation and Modelling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Biodiversity\u2014Ecological Modelling, Dahlem Center of Plant Science, Free University of Berlin, 14195 Berlin, Germany"}]},{"given":"Jing","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Global Change and Earth System Sciences, Beijing Normal University, Beijing 100875, China"}]},{"given":"Xianzhou","family":"Zhang","sequence":"additional","affiliation":[{"name":"Lhasa Plateau Ecosystem Research Station, Key Laboratory of Ecosystem Network Observation and Modelling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"}]},{"given":"Chunqiao","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Geography, University of California, Los Angeles, CA 90095, USA"}]}],"member":"1968","published-online":{"date-parts":[[2017,2,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6903","DOI":"10.1007\/s10661-014-3898-z","article-title":"The effects of grassland degradation on plant diversity, primary productivity, and soil fertility in the alpine region of Asia\u2019s headwaters","volume":"186","author":"Wang","year":"2014","journal-title":"Environ.
