| 1 | Soil Organic Carbon Mineralization as Affected by Cyclical Temperature Fluctuations in a Karst Region of Southwestern China显示文摘The diurnal fluctuation in soil temperature may influence soil organic carbon(SOC) mineralization, but there is no consensus on SOC mineralization response to the cyclical fluctuation in soil temperature. A 56-d incubation experiment was conducted to investigate the effects of constant and variable temperatures on SOC mineralization. Three soils were collected from the karst region in western Guizhou Province, southwestern China, including a limestone soil under forest, a limestone soil under crops and a yellow soil under crops. According to the World Reference Base(WRB) classification, the two limestone soils were classified as Haplic Luvisols and the yellow soil as a Dystric Luvisol. These soils were incubated at three constant temperatures(15, 20 and 25?C) and cyclically fluctuating temperatures(diurnal cycle between 15 and 25?C). The results showed that the 56-d cumulative SOC mineralized(C56)at the fluctuating temperatures was between those at constant 15 and 25?C, suggesting that the cumulative SOC mineralization was restricted by temperature range. The SOC mineralization responses to the fluctuating temperatures were different among the three soils, especially in contrast to those at constant 20?C. Compared with constant 20?C, significant(P < 0.05) decreases and increases in C56 value were found in the limestone soil under forest and yellow soil under crops at the fluctuating temperatures, respectively. At the fluctuating temperatures, the forest soil with lower temperature coefficient Q10(the relative change in SOC mineralization rate as a result of increasing the temperature by 10?C) had a significantly(P < 0.05) lower SOC mineralization intensity than the two cropland soils. These indicated that differences in temperature pattern(constant or fluctuating) could significantly influence SOC mineralization, and SOC mineralization responses to the fluctuating temperatures might be affected by soil characteristics.Moreover, the warmer temperatures might improve the ability of soil microbes to decompose the recalcitrant SOC fraction, and cyclical fluctuations in temperature could influence SOC mineralization through changing the labile SOC pool size and the mineralization rate of the recalcitrant SOC in soils. | CI En Mahdi M.AL-KAISI WANG Liange DING Changhuan XIE Deti | 2015 | Pedosphere2015,25,4: | 12 |
| 2 | Significant loss of soil inorganic carbon at the continental scale显示文摘Widespread soil acidification due to atmospheric acid deposition and agricultural fertilization may greatly accelerate soil carbonate dissolution and CO_(2) release.However,to date,few studies have addressed these processes.Here,we use meta-analysis and nationwide-survey datasets to investigate changes in soil inorganic carbon(SIC)stocks in China.We observe an overall decrease in SIC stocks in topsoil(0-30 cm)(11.33 g C m^(-2)yr^(-1))from the 1980s to the 2010s.Total SIC stocks have decreased by∼8.99±2.24%(1.37±0.37 Pg C).The average SIC losses across China(0.046 Pg C yr^(-1))and in cropland(0.016 Pg C yr^(-1))account for∼17.6%-24.0%of the terrestrial C sink and 57.1%of the soil organic carbon sink in cropland,respectively.Nitrogen deposition and climate change have profound influences on SIC cycling.We estimate that∼19.12%-19.47%of SIC stocks will be further lost by 2100.The consumption of SIC may offset a large portion of global efforts aimed at ecosystem carbon sequestration,which emphasizes the importance of achieving a better understanding of the indirect coupling mechanisms of nitrogen and carbon cycling and of effective countermeasures to minimize SIC loss. | Xiao-Dong Song Fei Yang Hua-Yong Wu Jing Zhang De-Cheng Li Feng Liu Yu-Guo Zhao Jin-Ling Yang Bing Ju Chong-Fa Cai Biao Huang Huai-Yu Long Ying Lu Yue-Yu Sui Qiu-Bing Wang Ke-Ning Wu Feng-Rong Zhang Ming-Kui Zhang Zhou Shi Wan-Zhu Ma Gang Xin Zhi-Ping Qi Qing-Rui Chang En Ci Da-Gang Yuan Yang-Zhu Zhang Jun-Ping Bai Jia-Ying Chen Jie Chen Yin-Jun Chen Yun-Zhong Dong Chun-Lan Han Ling Li Li-Ming Liu Jian-Jun Pan Fu-Peng Song Fu-Jun Sun Deng-Feng Wang Tian-Wei Wang Xiang-Hua Wei Hong-Qi Wu Xia Zhao Qing Zhou Gan-Lin Zhang | 2022 | National Science Review2022,9,2: | 2 |

| 14 | Endovascular management of traumatic arterial emergencies:A single center retrospective study显示文摘Objectives:To present our experience in delivering endovascular therapies for emergent vascular traumas with various vascular structures.Methods:Between September 2013 and February 2018,patients who underwent endovascular intervention due to penetrating,blunt and iatrogenic arterial traumas were analyzed,retrospectively.Demographic data,trauma site,mechanism of injury,angiographic findings or arterial injury patterns,treatment methods,and outcomes were recorded.Results:A total of 30 patients were included.The mean age of patients was 39 years(range:15-87 years).Arterial trauma locations were in the compressible area with a rate of 43%(n=13)and in the noncompressed area with a rate of 57%(n=17).Mechanisms of injuries were blunt[53%(n=16)],penetrating[17%(n=5)],and iatrogenic[30%(n=9)].The most common indication for endovascular treatment was blunt noncompressible injury(n=12).Methods used for treatment were stent-graft(46%,n=14)and coil embolization(54%,n=16).Immediate success was obtained in all procedures.The mean follow-up duration was 5 months(range:1-12 months).Conclusions:Endovascular treatments performed in traumatic arterial emergencies are effective and minimally invasive with very low complication rates even in hemodynamically unstable patients. | Erdem Birgi Hasanali Durmaz Kürşat Güreşci Onur Ergun GülşenÇığsar Burhan Kurtuluş Baki Hekimoğlu | 2021 | Journal of Acute Disease2021,10,6: | 0 |
