Lateral transport of soil carbon and land-atmosphere CO^sub 2^ flux induced by water erosion in China
Soil erosion by water impacts soil organic carbon stocks and alters CO^sub 2^ fluxes exchanged with the atmosphere. The role of erosion as a net sink or source of atmospheric CO^sub 2^ remains highly debated, and little information is available at scales larger than small catchments or regions. This...

520 | |a Soil erosion by water impacts soil organic carbon stocks and alters CO^sub 2^ fluxes exchanged with the atmosphere. The role of erosion as a net sink or source of atmospheric CO^sub 2^ remains highly debated, and little information is available at scales larger than small catchments or regions. This study attempts to quantify the lateral transport of soil carbon and consequent land-atmosphere CO^sub 2^ fluxes at the scale of China, where severe erosion has occurred for several decades. Based on the distribution of soil erosion rates derived from detailed national surveys and soil carbon inventories, here we show that water erosion in China displaced 180 ± 80 Mt C.y^sup -1^ of soil organic carbon during the last two decades, and this resulted a net land sink for atmospheric CO^sub 2^ of 45 ± 25 Mt C.y^sup -1^, equivalent to 8-37% of the terrestrial carbon sink previously assessed in China. Interestingly, the "hotspots," largely distributed in mountainous regions in the most intensive sink areas (>40 g C.m^sup -2^.y^sup -1^), occupy only 1.5% of the total area suffering water erosion, but contribute 19.3% to the national erosion-induced CO^sub 2^ sink. The erosion-induced CO^sub 2^ sink underwent a remarkable reduction of about 16% from the middle 1990s to the early 2010s, due to diminishing erosion after the implementation of large-scale soil conservation programs. These findings demonstrate the necessity of including erosion-induced CO^sub 2^ in the terrestrial budget, hence reducing the level of uncertainty. | ||

Based on the distribution of soil erosion rates derived from detailed national surveys and soil carbon inventories, here we show that water erosion in China displaced 180 ± 80 Mt C.y^sup -1^ of soil organic carbon during the last two decades, and this resulted a net land sink for atmospheric CO^sub 2^ of 45 ± 25 Mt C.y^sup -1^, equivalent to 8-37% of the terrestrial carbon sink previously assessed in China. Interestingly, the "hotspots," largely distributed in mountainous regions in the most intensive sink areas (>40 g C.m^sup -2^.y^sup -1^), occupy only 1.5% of the total area suffering water erosion, but contribute 19.3% to the national erosion-induced CO^sub 2^ sink. The erosion-induced CO^sub 2^ sink underwent a remarkable reduction of about 16% from the middle 1990s to the early 2010s, due to diminishing erosion after the implementation of large-scale soil conservation programs. These findings demonstrate the necessity of including erosion-induced CO^sub 2^ in the terrestrial budget, hence reducing the level of uncertainty.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Soil erosion</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Carbon dioxide</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Atmosphere</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Water</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Jinren Ni</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Philippe Ciais</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Shilong Piao</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Tao Wang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Mengtian Huang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Alistair G L Borthwick</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Tianhong Li</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Yichu Wang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Adrian Chappell</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Kristof Van Oost</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Proceedings of the National Academy of Sciences of the United States of America</subfield><subfield code="d">Washington, DC : NAS, 1877</subfield><subfield code="g">113(2016), 24, Seite 6617</subfield><subfield code="w">(DE-627)129505269</subfield><subfield code="w">(DE-600)209104-5</subfield><subfield code="w">(DE-576)014909189</subfield><subfield code="x">0027-8424</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:113</subfield><subfield code="g">year:2016</subfield><subfield code="g">number:24</subfield><subfield code="g">pages:6617</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://search.proquest.com/docview/1799232052</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">FID-LING</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">FID-BIODIV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHY</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-CHE</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-MAT</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-FOR</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-DE-84</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OPC-MAT</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OPC-FOR</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_40</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_59</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">113</subfield><subfield code="j">2016</subfield><subfield code="e">24</subfield><subfield code="h">6617</subfield></datafield></record></collection>

Lateral transport of soil carbon and land-atmosphere CO^sub 2^ flux induced by water erosion in China |
abstract |
Soil erosion by water impacts soil organic carbon stocks and alters CO^sub 2^ fluxes exchanged with the atmosphere. The role of erosion as a net sink or source of atmospheric CO^sub 2^ remains highly debated, and little information is available at scales larger than small catchments or regions. This study attempts to quantify the lateral transport of soil carbon and consequent land-atmosphere CO^sub 2^ fluxes at the scale of China, where severe erosion has occurred for several decades. Based on the distribution of soil erosion rates derived from detailed national surveys and soil carbon inventories, here we show that water erosion in China displaced 180 ± 80 Mt C.y^sup -1^ of soil organic carbon during the last two decades, and this resulted a net land sink for atmospheric CO^sub 2^ of 45 ± 25 Mt C.y^sup -1^, equivalent to 8-37% of the terrestrial carbon sink previously assessed in China. Interestingly, the "hotspots," largely distributed in mountainous regions in the most intensive sink areas (>40 g C.m^sup -2^.y^sup -1^), occupy only 1.5% of the total area suffering water erosion, but contribute 19.3% to the national erosion-induced CO^sub 2^ sink. The erosion-induced CO^sub 2^ sink underwent a remarkable reduction of about 16% from the middle 1990s to the early 2010s, due to diminishing erosion after the implementation of large-scale soil conservation programs. These findings demonstrate the necessity of including erosion-induced CO^sub 2^ in the terrestrial budget, hence reducing the level of uncertainty. |
