Effect of Snow-cover Duration on Plant Species Diversity of Alpine Meadows on the Eastern Qinghai-Tibetan Plateau

Although snow cover plays an important role in structuring plant diversity in the alpine zone, there are few studies on the relationship between snow cover and species diversity of alpine meadows on the eastern Qinghai-Tibetan Plateau. To assess the effect of snow cover on plant species diversity of alpine meadows, we used ten parallel transects of 60 m × 1 m for this study and described the changes in species diversity and composition associated with snow depth. With the division of snow depth into six classes, the highest species richness （S） and species diversity （H′） occurred with an intermediate snow depth, i.e., class Ⅲ and class Ⅳ, showing a unimodal curve with the increase in snow depth. The relationship between snow depth and plant diversity （both richness and Shannon index） could be depicted by quadratic equations. There was no evident relationship between diversity （both S and H′） and soil water content, which implied that other more important factors influenced species diversity. The patterns of diversity found in our study were largely attributed to freeze-thaw alteration, length of growing season and disturbances of livestock grazing. Furthermore, snow depth affected species composition, as evaluated by the Sorensen＇s index of similarity. In addition, almost all species limited to one snow depth class were found only in class Ⅲand class Ⅳ, indicating that intermediate snow depth was suitable for the survival and growth of many alpine species.

ANALYSIS ON INTRA-ANNUAL INHOMOGENEITY OF RAINSTORM EVENTS IN GUANGXI

Based on the daily precipitation data of 83 stations in Guangxi and the NCEP/NCAR monthly reanalysis data from 1979 through 2008, the characteristics of spatial and temporal distribution and variation of the rainstorm concentration degree(RCD) and the rainstorm concentration period(RCP) are analyzed by using the methods of Monte Carlo test etc. The results are shown as follows. The rainstorm events are concentrated in April-September, taking up about 90% of the yearly rainfall total, and the percentages of rainstorms in the annual total precipitation have an increasing tendency. RCD in the east of Guangxi is larger than that in the west. The RCP in the northeast and southwest of Guangxi is later than that in the other regions, and has the earliest onset in the northern mountainous regions of Baise and southeast Guangxi. The RCD exhibits an increasing tendency in the northwest and the coastal region while showing a decreasing tendency in the other regions. On a long-term basis, the RCP in the east and coastal region has a postponing trend but tends to be earlier in the other regions. The proposed mechanism is as follows: If the geopotential height in the south of Qinghai-Tibet Plateau and the West Pacific has a highly negative anomaly in winter, the western Pacific subtropical high will be strong in summer, which increases the RCD in Guangxi. If the geopotential height has a highly positive anomaly in winter, the subtropical high will have a significant periodic oscillation in summer, which decreases the RCD in Guangxi. The value of RCD is high(low) in the area of northern mountainous regions of Guangxi and Beihai in strong(weak) South China Sea summer monsoon years, while in the other areas, the value of RCD is low(high).

High-altitude gastrointestinal bleeding:An observation in Qinghai-Tibetan railroad construction workers on Mountain Tanggula

AIM: To investigate the gastrointestinal bleeding (GIB) in people from lowland to high altitude and in workers on Mountain Tanggula and its causes as well as treatment and prophylaxis.METHODS: From 2001 to October 2003, we studied GIB in 13 502 workers constructing the railroad on Mountain Tanggula which is 4905 m above the sea level. The incidence of GIB in workers at different altitudes was recorded. Endoscopy was performed when the workers evacuated to Golmud (2808 m) and Xining (2261 m). The available data on altitude GIB were analyzed.RESULTS: The overall incidence of GIB was 0.49% in 13 502 workers. The incidence increased with increasing altitude. The onset of symptoms in most patients was within three weeks after arrival at high altitude. Bleeding manifested as hematemesis, melaena or hematochezia, and might be occult. Endoscopic examination showed that the causes of altitude GIB included hemorrhage gastritis, gastric ulcer, duodenal ulcer, and gastric erosion. Experimental studies suggested that acute gastric mucosal lesion (AGML) could be induced by hypoxic and cold stress, which might be the pathogenesis of altitude GIB. Those who consumed large amount of alcohol, aspirin or dexamethasone were at a higher risk of developing GIB. Persons who previously suffered from peptic ulcer or high-altitude polycythemia were also at risk of developing GIB. Early diagnosis, evacuation, and treatment led to early recovery. CONCLUSION: GIB is a potentially life threatening disease, if it is not treated promptly and effectively. Early diagnosis, treatment and evacuation lead to an early recovery. Death due to altitude GIB can be avoided if early symptoms and signs are recognized.

Medical mountain rescue in the Yushu Earthquake: Have lessons been learned?

On April 14,2010,an earthquake reaching Richter scale 7.1 struck Jiegu Town of Yushu,a mountain rescue operation promptly launched. All injurers had a direct assess to take medical care,and were immediately rescued and rapidly evacuated by air to Xining and Golmud at lower altitudes and admitted to advanced hospitals. Almost all of the injurers have been completely recovered. Yushu Earthquake was one of the highest earthquakes in the world,with a high incidence of acute altitude illness,which was observed in about 80 % of the lowland rescuers at an altitude of 4 000 m."Rescue the rescuers"became the major task of Qinghai-Tibetan rescue teams,all the severe patients were rapidly descended to Xining and treated promptly and effectively. The outcome was excellent,all patients survived. After the earthquake,it is a long and arduous task to reconstruct what has been destroyed. Medical teams continue to work in the Yushu Earthquake area because about 30 000 workers and carders are now here for rebuilding the earthquake center. Thus the prevention and treatment of altitude illness are still critical tasks for medical teams. Although all the fights are successful,there are more experiences and lessons we have learned from the medical mountain rescue during the earthquake and the reconstruction,and reports here are to sum up our experiences from the medical mountain rescue operation in Yushu Earthquake and draw the lessons that we should learn. With the increasing of earthquake probability occurring in the Qinghai-Tibetan Plateau,we also should prepare against earthquake disasters and for further rescue training in the high mountains.

Overall-effective Measures for Sustainable Water Resources Management in the Coastal Areas of Shandong Province, China——Case Study: the Huangshuihe River Catchment of Longkou City

In the coastal catchments of Shandong Province the water scarcity is aggravated due to saltwater intrusion, reducing the usability of water resources available. Such a situation calls for sustainable integrated water resources management (IWRM). The idea for the objectives and implementation of the IWRM are explained in this paper. The general objective of the planned project disscussed in the present study is to bring together German traditional expertise in water resources management and newer developments in the context of the European Water Framework Directive; the research efforts aim to relieve the desperate water scarcity situation in the costal area of Shandong Province.

Ataxia,acute mountain sickness,and high altitude cerebral edema

Previous investigations suggest that ataxia is common and often one of the most reliable warning signs of high altitude cerebral edema(HACE). The aim of this study was to investigate the diagnostic role of ataxia in acute mountain sickness(AMS)and HACE among mountain rescuers on the quake areas,and in approaching the relation between AMS and HACE. After the earthquake on April 14,2010,approximately 24 080 lowland rescuers were rapidly transported from sea level or lowlands to the mountainous rescue sites at 3 750 ~ 4 568 m,and extremely hardly worked for an emergency treatment after arrival. Assessments of acute altitude illness on the quake areas were using the Lake Louise Scoring System. 73 % of the rescuers were found to be developed AMS. The incidence of high altitude pulmonary edema(HAPE)and HACE was 0.73 % and 0.26 %,respectively,on the second to third day at altitude. Ataxia sign was measured by simple tests of coordination including a modified Romberg test. The clinical features of 62 patients with HACE were analyzed. It was found that the most frequent,serious neurological symptoms and signs were altered mental status(50/62,80.6 %)and truncal ataxia(47/62,75.8 %). Mental status change was rated slightly higher than ataxia,but ataxia occurred earlier than mental status change and other symptoms. The earliest sign of ataxia was a vague unsteadiness of gait,which may be present alone in association with or without AMS. Advanced ataxia was correlated with the AMS scores,but mild ataxia did not correlate with AMS scores at altitudes of 3 750~4 568 m. Of them,14 patients were further examined by computerized tomographic scanning of the brain and cerebral magnetic resonance imagines were examined in another 15 cases. These imaging studies indicated that the presence of the cerebral edema was in 97 % of cases who were clinically diagnosed as HACE(28/29). Ataxia seems to be a reliable sign of advanced AMS or HACE,so does altered mental status.

Spatial-temporal variance of reclamation soil physical and chemical character in opencast mine region

In order to study the effects of soil compaction, and soil physical and chemicalcharacteristics after land reclamation, selected lands that were reclaimed after 1, 2, 3, 4,and 5 a, respectively, in the Majiata Mine of the Shendong Open Pit; tested the effects ofsoil compaction; and collected soil samples from 5 different depths, which are 0-7.62,7.62-15.24, 15.24-22.86, 22.86-30.48, and 30.48-38.10 cm, respectively. The resultsshow that: Land reclamation leads to soil compaction. The lowest effect of soil compaction is in the top layer and the highest one at the depth of 20-30 cm; The bulk density of reclaimed soil is higher than that of undisturbed soil; this declines with the reclamation and nearly reaches the level of undisturbed soil after 5-year reclamation;The content of reclaimed soil nutrients is lower than that of undisturbed soil. The lowest one is inthe soil dumping site, which reaches the level of undisturbed soil after 5-year reclamation;The pH value of reclaimed soil is lower than that of undisturbed soil. The highest one isin the soil dumping site; this declines with the reclamation.

Recent Climate Trends on the Northern Slopes of the Tianshan Mountains, Xinjiang, China

In arid regions, mountains fulfill important ecological and economic functions for the surrounding lowlands. In the scenario of global warming, mountain ecosystems change rapidly, especially in the arid region of northwestern China. This paper provides an assessment of the changes in temperature and precipitation in the historical records of climate on the northern slopes of the eastern Tianshan Mountains. A Mann-Kendall nonparametric trend and Sen＇s tests are employed to analyze the interannual changes and innerannual variability in temperature and precipitatiofi in the regions of low to high altitude. The present study finds that the largest increases in annual temperature are observed at stations in the low altitude regions. The significant increasing trends in temperature tend to occur mainly in late winter and early spring at stations from middle to high altitude, but in summer and autumn at stations of low altitudes. The increasing trends in annual precipitation are found from the middle to high altitude areas, but decreasing trends are found in the low altitude areas. The significant increasing trends in precipitation occur mostly in winter and earlier spring at stations from the middle to high altitudes, while the increasing and decreasing trend coexists at stations of low altitude with most of the significant trend changes occurring in March, June and August.

System Dynamics Modeling for Sustainable Water Management of a Coastal Area in Shandong Province, China

Water is one of the basic materials in human existence and the development of society and economy. Its sustainable management has always been an eternal subject for the management of human society and also a complex systemic problem. How to take advantages of water has been a big event in such an agricultural country like China. As economically developed areas, coastal areas are facing water shortage problems due to the rapid economic and social development and inappropriate and unsustainable water management measures. To fully understand and study such problems faced by the coastal areas needs a systematic and integrated framework to consider the various social-economic, natural and engineering factors that affect the sustainable development of water in those areas. The SD （system dynamics） methodology, which is an approach that has been successfully used in solving complex systematic problems in general, and in solving water management problems in particular for more than 50 years, was applied to a typical coastal area, Longkou City in Shandong Province of China, to study and analyze the future sustainable water management of this city. Then the quantitative modeling and analysis of the water development were carried out through scenario analysis. Four different scenarios （business as usual, economic development, water resources protection, and comprehensive） were designed by changing the values of decision-making variables. The total water demand in 2030 of these four scenarios are 0.455 billion m3, 0.793 billion m3, 0.412 billion m3 and 0.487 billion m3, respectively; the corresponding water deficit of these scenarios are 0.292 billion m3, 0.634 billion m3, 0.254 billion m3 and 0.329 billion m3, respectively. The comparison results indicated that the comprehensive scenario is the optimal one among these designed scenarios. To totally solve the water shortage problem with the economy developed in Longkou City needs to take more effective measures to reduce water consumption and improve water conservation technologies.

Maternal genetic structure in ancient Shandong between 9500 and 1800 years ago

Archaeological and ancient DNA studies revealed that Shandong,a multi-culture center in northern coastal China,was home to ancient populations having ancestry related to both northern and southern East Asian populations.However,the limited temporal and geographical range of previous studies have been insufficient to describe the population history of this region in greater detail.Here,we report the analysis of 86 complete mitochondrial genomes from the remains of 9500 to 1800-year-old humans from12 archaeological sites across Shandong.For samples older than 4600 years before present(BP),we found haplogroups D4,D5,B4 c1,and B5 b2,which are observed in present-day northern and southern East Asians.For samples younger than 4600 BP,haplogroups C(C7 a1 and C7 b),M9(M9 a1),and F(F1 a1,F2 a,and F4 a1)begin to appear,indicating changes in the Shandong maternal genetic structure starting from the beginning of the Longshan cultural period.Within Shandong,the genetic exchange is possible between the coastal and inland regions after 3100 BP.We also discovered the B5 b2 lineage in Shandong populations,with the oldest Bianbian individual likely related to the ancestors of some East Asians and North Asians.By reconstructing a maternal genetic structure of Shandong populations,we provide greater resolution of the population dynamics of the northern coastal East Asia over the past nine thousand years.

Spatial distribution of marine chemicals along a transect from Zhongshan Station to the Grove Mountain area, Eastern Antarctica

This study investigates the regional distribution of marine aerosol originated species （Na＋, CI-, nss-SO42- and MSA） in the snow pits （or firn cores） collected along a transect between Zhongshan Station and the Grove Mountain area （450 km inland） on the eastern side of the Lambert Glacier Basin. Concentrations of Na＋ and Cl- decrease exponentially with distance from the coast to 100 km inland （i.e., 1500 m a.s.1.）. Statistical results demonstrate that distance from the coast inland and elevation af-fect the concentration of sea-salt originated ions in inland areas significantly. Increase of Cl-/Na＋ ratio and higher variability in its standard deviation suggest that there are other sources of ions in addition to sea-salt in inland areas of the Antarctic conti- nent. The concentrations of Na＋ and Cl- from nine sampling sites in the Grove Mountain area are relatively higher than those from sites along CHINARE transect, although all sites are at similar distance inland. This phenomenon indicates that the barri- er effect of the mountain may be the most important factor influencing ion deposition. In addition, nss-SO42- and MSA vary differently, with nss-SO42- decreasing with distance more significantly. This implies that sources and transporting pathways influence the deposition of the two sulfur compounds considerably, being supported by the spatial pattern of correlation coeffi- cients between the nss-SO42- and MSA.

Discovery of fossil Nemacheilids (Cypriniformes,Teleostei,Pisces) from the Tibetan Plateau,China

Here described are the nemacheilid fossils from the Pliocene Lower Member of Qiangtang Formation in the Kunlun Pass Basin,northeastern Tibetan Plateau,at a locality 4769 m above the sea level (a.s.l.).The materials consist of numerous disarticulated and incomplete bones.The fish remains are assigned to the Nemacheilidae based on the fused compound centrum of the 2nd and 3rd vertebrae with developed bifurcate lateral processes of the 2nd vertebra.The fossils also include the maxilla,the dentary,the anguloarticular,the quadrate,the hyomandibular,the opercle,the basihyal,the urohyal,the anterior ceratohyal,the posterior ceratohyal,the interhyal and the supracleithrum.These bones are very similar to their counterparts in some species of a Recent nemacheilid genus,Triplophysa (Nemacheilidae,Cypriniformes),which is widely distributed on the Tibetan Plateau.The nemacheilid fossils are much more abundant than the remains of schizothoracines embedded in the same horizon at the same locality.This would imply that the number of individuals of Triplophysa was much higher than that of schizothoracines when they were alive in the area.In Recent ichthyofauna of the Tibetan Plateau,Triplophysa prevails over schizothoracines in the number of individuals in the high elevations and small water bodies.Based on the fossil dominance of Triplophysa over schizothoracines and their taphonomical conditions,it appears that the water system at the Kunlun Pass area during the Pliocene might not be extensive lakes or large rivers with broad valleys.There might have been a few mountainous,relatively torrential rivers with many small,shallow streams connecting the water systems from the north and south of the East Kunlun Mountain.The environment of the Kunlun Pass Basin area during the Pliocene must be very harsh,and the altitude of the area might already have been higher than we previously suggested.The uplift of the area must be less than 1000 m since the Pliocene.
