| 1 | Temperature variations in the past 6000 years inferred from δ^(18)O of peat cellulose from Hongyuan,China显示文摘Trends of the temperature variations recorded in δ18O in Hongyuan peat cellulose are similar to those recorded in δ18O of Jinchuan peat cellulose and in δ18O of Dunde ice core. Climate events have been identified to be globally homogeneous. Two notable climate transition periods have been detected in the past 6000 years, namely 4000 aBP with climate shifting from cold to warm and 1500 aBP with climate shifting from warm to relatively cold. Power spectrum analysis was performed to investigate the periodical signals in the δ18O time series. Typical periodicities of 1200-1087 a, 752 a, 444 a, 325 a, 213 a, 127-123 a, 88 a, 79 a were discovered, indicating an integrated influence on Hongyuan climate from solar, monsoon and ocean activities. Solar forcing has been addressed to be the main driving forcing of Hongyuan climate. | XU Hai, HONG Yetang, LIN Qinghua, HONG Bing, JIANG Hongbo & ZHU YongxuanInstitute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002, China Graduate School of Chinese Academy of Sciences, Beijing 100039, China | 2002 | Chinese Science Bulletin2002，47，18： | 31 |
| 2 | Glacier Extent and Volume Change(1966~2000) on the Su-lo Mountain in Northeastern Tibetan Plateau,China显示文摘The topographic maps of 1:50,000 scales,aerial photographs taken in 1966,one Landsat image taken in 1999,and SRTM data from 2000 were used to quantify the losses in area and volume of the glaciers on the Su-lo Mountain,in the northeastern Tibetan Plateau,China in the past 30 years.The total glacier area decreased from 492.9km2 in 1966 to 458.2km2 in 1999.The volume loss of the studied glaciers reached 1.4 km3 from 1966 to 2000.This agrees with documented changes in other mountain glaciers of the whole Tibetan Plateau. | WANG Yetang HOU Shugui HONG Sungmin HUR Soon Do LIU Yaping | 2008 | Journal of Mountain Science2008，5，4： | 10 |
| 3 | Effect of red mud on the mobility of heavy metals in mining-contaminated soils显示文摘The mobility of Cu2+, Zn2+, Ni2+, and Cd2+ in soils treated with red mud was experimentally studied to explore the feasibility of remediation of smelter-contaminated soils. Red mud samples were collected with the Bayer process (BRM) and confederate process (CRM) in the Aluminous Plant of Guizhou Province. Two farmed soil samples were collected from the Niujiaotang mining area, Guizhou Province, Southwest China. One sample was weakly polluted by fly ash; and the other was polluted severely by waste water from the smelter. For evaluating the potential of remediation, the concentrations of free metal ions and the distributions of metals in the soil were determined. The concentrations of free metal ions were measured by using the Donnan Membrane Technique, and the contributions of soil sorbents to the heavy metals adsorptions were calculated with Equilibrium Calculation of Speciation and Transport (ECOSAT). BRM reduced the concentrations of free metal ions in two kinds of soils, while CRM only favored the decrease of the concentrations of free metal ions in seriously contaminated soils. The experimental data also showed a tendency that the concentrations of free metal ions decreased proportionally with the amount of added red mud, which resulted from the increasing adsorption of heavy metal ions in the form of metal ion hydroxides. | YI Li HONG Yetang WANG Duojun ZHU Yongxuan | 2010 | Chinese Journal Of Geochemistry2010，29，2： | 9 |
| 4 | Interconnections between the Asian monsoon,ENSO,and high northern latitude climate during the Holocene显示文摘The article emphatically reviews the research progress in interconnections between the East Asian and Indian Ocean summer monsoons, between the Asian monsoon and the El Ni?o-South- ern Oscillation (ENSO) activity, and between the monsoon, ENSO and the changing of the North At- lantic climate during the Holocene. According to the studies of recent years, it is found that the intensity variations of the East Asian and Indian Ocean sum- mer monsoons show an opposite relationship, which may be closely related to the phenomena of ENSO in the equatorial Pacific Ocean and the variation of the deep-water formation of the North Atlantic Ocean on the interannual to orbital time scales. The 4k and 8k events occurring at around 4200 and 8200 a BP, re- spectively, might be the two in a series of severe pa- leo-El Ni?o events during the Holocene, strongly re- flecting the interactions and influences of the mon- soons, ENSO and the North Atlantic climate. In order to better understand the relationships between these paleoclimatic phenomena, scientists need to strengthen the research work on the Asian monsoon division and the comparison between monsoon proxy records, and the study on the proxy record of sea surface temperature with high time-resolution in the equatorial Pacific Ocean and the simulation research of paleoclimate condition. | HONG Bing LIN Qinghua HONG Yetang | 2006 | Chinese Science Bulletin2006，51，18： | 6 |
| 5 | Biological effect of rare-earth elements on anti-oxidation enzymes in wheat under acid rain stress显示文摘Based on pot-culture experiments, the biological effect of rare-earth elements (REE) on antioxidation enzymes of wheat under acid rain stress was studied. The results show that both acid rain and REE can affect the activity of anti-oxidation enzymes of wheat to different extents. Under the acid rain stress, anti-oxidation enzymes (CAT, SOD) of wheat showed single peak curve with the decrease of pH values. After REE were applled, variation of activities of anti-oxidation enzymes was relatively stable and the peak value of variation curve would move in the direction of increased acidity. Under low acidity of acid rain, REE could reduce the sensitivity of anti-oxidation enzymes of wheat to acid rain stress significantly and promote the resistance of anti-oxidation enzymes of wheat to acid rain. | Chongling Yan Yetang Hong Xianke Yang Shunzhen Fu Shanyi Wu | 1999 | Chinese Science Bulletin1999，44，2： | 5 |
| 6 | The influence of volcanism on paleoclimate in the northeast of China:Insights from Jinchuan peat,Jilin Province,China显示文摘Just like contemporary sediments, peat itself is a good repository of information about climate change, the effects of volcanic activity on climate change have been truly recorded in peat, since it is a major archive of volcanic eruption incidents. A section of sand was identified as tephra from the Jinchuan peat, Jilin Province, China, for the grains look like slag with surface bubbles and pits, characterized by high porosity, and loose structure with irregular edges and corners. According to the peat characteristics of uniform deposition, the tephra was dated at 2002-1976 a B.P. by way of linear interpolation, so the time of volcanic eruption was 15 B.C.-26 A.D. (the calibrated age). While the geochemical characteristics of tephra in this study are quite the same as those of tephra from the Jinlongdingzi volcano at Longgang and from alkaline basaltic magma, with the contents of SiO2<55%, and the similar contents to Al2O3 and Fe, but the contents of Na2O>K2O. We speculated that the tephra in this study came from the Longgang volcano group. Compared with 11 recorded volcanic eruption events as shown on the carbon and oxygen isotope curves of the Jinchuan peat cellulose, it is obviously seen that adjacent or large-scale volcanic eruptions are precisely corresponding to the minimum temperature and humidity. It seems that these volcanic eruptions indeed affected the local climate, leading to the drop of regional temperature and humidity. As a result, there was prevailing a cold and dry climate there, and all these changes can be well recorded in peat. So the comparison of volcanic eruption events with information about climate change developed from peat, can provide strong evidence for the impact of volcanism on climate change. | MAO Xumei CHENG Shenggao HONG Yetang ZHU Yongxuan WANG Fenglin | 2009 | Chinese Journal Of Geochemistry2009，28，2： | 5 |

| 8 | The potential effect of variations in climate and agricultural practice on N_2O emissions (Ⅱ)——Variations in agricultural practice显示文摘WE expanded Decomposition-Denitrification (DNDC)modeling study to systematically assess the potential effect of farming practice on N2O emission by choosing a corn-rape rotation and a soybean-winterwheat rotation field in Guizhou Province, westsouthern China, asN2O emission from subtropical agricultural soil study plots. These sensitivity studies address questions relevant to issue of how change in fanning practice might be used to mitigate emissions. Manure additions had the most pronounced impact on N2O emissions of farming practice simulatedand the influence of manure addition was nonlinear (fig. 1). This result is consistent with previous studies for an Iowa corn field. The addition of manure remarkably elevates the level of organic carbon, enhances soil nitrogen mineralization, and increases the efficiency of N2O production. Simulated results alsoshowed that the influence of manure additions on N2O emission from soybean-winter wheat field had | XU Wenbin~(1,2), HONG Yetang~1, CHEN Xuhui~3, LI Changsheng~4, LIN Qinghua~1 and WANG Yu~1, 1.

| 14 | Effect of Pb, Hg and Cd in soil on scavenging system of activated oxygen in tobacco leaves显示文摘Pb, Hg and Cd will affect human health by vegetative chain. In recent years, people more and more are concerned about heavy metal pollution of the soil-plant system. Many researchers studied the effect of single heavy metal on growth, photosynthesis, respiration and quality of plants, but few systematicstudies of the effect of heavy metals on the scavenging system of activated oxygen of plants.

| 16 | Nitrogen and oxygen isotope budget balance in tropospheric N_2O显示文摘THK N2O is an important greenhouse gas. In the steady state the stable isotopic composition of nitrogenand oxygen in tropospheric N2O is balanced by isotopically light N2O emitted from soils and oceans andisotopically heavy N2O as return flux from the stratosphere. However, no such balance was reached incalculations given by Kim and Craig. This serious discrepancy lied in the fact that only soil and oceanic sources were considered in Kim and Craig’s calculation and N2O emission from tropical forest soil wastaken as the global soil contribution. Progress since the 1990s in identifying additional sources of atmospheric N2O as well as in the estimation from various types of soil allows us to make more realistic assessment of nitrogen and oxygen isotope balance budgets in tropospheric N2O. In this note, modification willbe proposed of atmospheric N2O nitrogen and oxygen isotope budgets to Kim and Craig’s calculation. The static balance of nitrogen and oxygen isotopes in tropospheric N2O is expressed | XU Wenbin~(1,2) and HONG Yetang~1 1.

| 17 | The influence of temperature on diurnal and seasonal variations of N_2O flux from agricultural soilis in Guizhou显示文摘AGRICULTURAL soils are the major anthropogenic source of N2O, and temperature is one of the importantenvironmental factors controlling production and emission of N2O from soil. This work focuses on the influence of temperature on diurnal and seasonal variations of N2O flux from subtropical agricultural soil.This was done by seasonal measuring N2O flux and soil temperature at a corn-rape rotation, a soybeanwinter wheat rotation and a fallow field (106°66’E, 26°50’N, 1140 m a.s.1.), at Soil and Fertilizer Institute, Guizhou Academy of Agricultural Sciences. Available nitrogen content of above three fields wasapproximately 0.71%, organic matter content 10.6-12.0 g/kg, clay (<2 μm) content 25.6%-30.0%, and pH was about 7.5 throughout the whole experiment. Measuring period was between 20 Mar. | XU Wenbin~(1,2), HONG Yetang~1, CHEN Xuhui~3, QIN Song~3 and JIANG Taiming~3 1.

| 19 | Characteristics of rare earth elements in soils in Guizhou carbonate region显示文摘IN recent years, rare earth element (REE) being used in agriculture has gained greater progress and madeus reach some common views. The centent of REE (especially soluble REE) in soils has significantcorrelation with that of REE plant absorbed from soil. Therefore, it is very necessary to clarify contentvariation and background values of REE (especially soluble REE ) from the angles of relation of supplyand demand between soil and plants, for reasonably using REE and formulating relevant health standardin the region, avoiding excessive using REE and taking up soil environmental capacity of REE to result insoil or water-body polluted and sometime for researching rock weathering, soil-forming process and soilclassification in the region. This note deals with characteristics of content and distribution of REE andsoluble REE in soils of Guizhou carbonate region. | YAN Chongling~(1,2), HONG Yetang~1, WANG Shijie~1, FU Shunzhen~2, ZHU Keyong~2 and WU Shanqi~2 1.

| 20 | Changes or soil microbial biomass carbon and orgamc carbon with sea level elevation increasing in soils of mountainous areas, Southwest China显示文摘SOIL organic matter, a major factor affecting agroecosystem stability, is controlled by many parameters. Itis well understood that cultivation practive would lead to a decrease in organic matter content of soils.However, small gradual changes in total soil organic matter may be difficult to monitor and detect in theshort term because of generally high background carbon levels and natural variability of soils. On ashort-term scale the measurement of the living fraction of soil organic matter, i.e. microbial biomass C,can reveal early changes in soil organic matter. Our work is to identify the relationship of soil organic Cand changes in microbial biomass C with sea-level elevation increasing. Twelve terrace fields on the slopes at different altitudes above sea level were chosen as sample localities. The terrace fields, different in size, approximately 10 m^2, were used for growing maize.
