Abstract: A dynamic simulating model of land desertification in the Naiman Banner, Inner Mongolia was established by means of system dynamic theory. The land desertification system in the Naiman Banner consists of five subsystems, i.e., farming, forestry, animal husbandry, grassland and population. According to positive-negative feedback relations in the land desertification, 75 equations were built and carried out schematic prediction with IBM PC/XT computer by using Micro-Dynamo language- With farming, forestry and animal husbandry forming three different landuse schemes, the desertification developmental trends in the banner up to 2040 were predicted. Predictions showed that the best landuse structures for farming, forestry and animal husbandry in the banner will be 15: 23: 62 in 2000; 16: 31: 53 in 2020 and 18: 44: 38 in 2040. Such a dynamic change of landuse structure will effectively control the desertification process and gain the best economic and ecological benefits.

Abstract: The Wulanhua Fauna (~7 Ma) derives from the basal part of Late Miocene red clays in Siziwang Banner, Inner Mongolia. Chinese red clay deposits are rich in fossils of the Hipparion fauna, and are relatively widely distributed across Shanxi, Shaanxi, Henan, and Gansu provinces. The Mongolian Plateau also contains well-developed Neogene deposits, especially in central Inner Mongolia, where a sequence of mammalian faunas has been identified. The discovery of the Wulanhua Fauna provides an important indicator of the paleogeographical distribution of the Hipparion fauna, and this study also contributes to a better understanding of the climatic and environmental significance of red clays. Most forms of the Wulanhua Fauna are the same as or close to taxa within the Baode Fauna. However, some forms are slightly more derived than those of the Baode Fauna, which may indicate a slightly younger geological age of about 7 Ma. The components of the Wulanhua Fauna suggest that the habitat was a typical steppe and therefore yield direct evidence to delineate the boundary between the east and west subregions of the Late Miocene Hipparion fauna in North China.

Abstract: Lots of gold deposits exist in Harqin Banner area within the eastern part of Inner Mongolia. Using the ETM+ remote sensing technique combined with field work,the authors extracted and analyzed the wall rock alteration and mineralization information of gold deposits in this area. The results show that the distribution of gold deposits in this area are obviously controlled by regional tectonics, and alterations related to gold mineralization are composed mainly of silicification and ferruginous minerals, with minor clay minerals. Three ore-forming belts are developed in this area, consisting of two EW-trending belts and one NE-SW-trending belt. The favorable area for gold mineralization lies in the southeast of the Harqin Banner area,and rich gold ore bodies might exist in the intersections between EW-trending faults and NE-SW-trending faults, where wall rock alterations are relatively intense. It is shown that the remote sensing information of mineralization and alteration can clearly reveal the potential areas of gold mineralization, and hence has some guiding significance in the exploration of gold deposits.

Abstract: 摘要: 内蒙古东乌珠穆沁旗北部的查干敖包岩体可分解为灰黄色细粒花岗岩单元和灰黄色中细粒似斑状含二云母花岗岩单元。前者锆石UPb加权平均年龄为(3064±2) Ma,为晚石炭世岩浆活动产物,后者锆石UPb加权平均年龄为(2783±2) Ma,为早二叠世岩浆活动产物。两期花岗岩具有相似的地球化学特征,主量元素均具有富Si,贫Ti、Mg、Ca,且有较高的碱/铝(NK/A)比值等特征;均表现出明显的负Eu异常;微量元素富集Rb、Th、U、K,弱富集P、Zr及Hf,强烈亏损Ba、Sr及Ti。通过分析讨论,认为晚石炭世晚期细粒花岗岩单元和早二叠世中细粒似斑状花岗岩单元的成因类型均为I-S过渡型钙碱性花岗岩。岩石化学、岩体产状、分布特点和源岩特征都表明,查干敖包岩体晚石炭世晚期和早二叠世花岗岩构造背景环境一致,均为晚古生代中亚造山大地构造背景下碰撞后转换期构造—岩浆事件产物。
Abstract: The Chaganaobao pluton in the north of the East Ujimqin Banner,Inner Mongolia can be divided into grayyellow finegrained granite unit and grayyellow medium-finegrained porphyraceous medium-finegrained twomica granite unit.The UPb weighted average age of the former is (3064±2) Ma,which is the product of Late Carboniferous magmatic activity.The latter has a UPb weighted average age of (2783±2) Ma,which is the product of Early Permian magmatic activity.The two kinds of granites have similar geochemical characteristics.The main elements are all rich in Si,but poor in Ti,Mg,Ca and have a high ratio of alkali/aluminum (NK/A),all of which show obvious negative Eu anomalies.Trace elements are enrichment of Rb,Th,U,K and are low enrichment of P,Zr,Hf,and have a strong loss of Ba,Sr,Ti.Based on the analysis and discussion,we conclude that the Late Carboniferous granite unit and the Early Permian mediumfinegrained porphyraceous granite unit are all the IS transitional calcalkaline granite type.The petrochemistry,rock formations,distribution and rocks sources all indicate that the late Late Carboniferous and early Permian granite body of the Chaganaobao were consistent with the product of the Late Paleozoic Central Asia orogenic tectonic setting and transformation period tectonicmagmatic event

Abstract: Meteorological observations show that Uxin Banner, situated in Ordos City, Inner Mongolia, has experienced a rising trend in annual mean temperature and strong rainfall variability during past decades, with an increase in drought frequency. Based on methods of questionnaire survey, semi-structured interview, and mathematical statistics, farming and grazing households in Uxin Banner were interviewed in 2009 concerning their perceptions on climate change, quantification of the influence on their livelihoods, the major methods used by farmers and herders to adapt to climate change, and factors affecting their choice of methods and the barriers to adaptation. Results are given as follows. 1) Decreased rainfall and rising temperature were generally recognized across the agricultural and animal husbandry areas. Drought was found to be the most recognized meteorological disaster affecting the livelihoods of farmers and herders in Uxin Banner, followed by rising temperature and increasing sand wind. Most of respondents believe that droughts lead to poor growth and declined production. Over the grassland area, 77.6% of herders interviewed have artificially sown pastures in their families for bad grass and decreased production of natural grassland. Almost all artificially sown pastures are irrigated. In agricultural areas, irrigation was not practiced before 1982 for high rainfall and shallower ground water. Irrigated agriculture has emerged as a result of decreased rainfall and increased droughts since 2000; 2) Different areas differ in their vulnerability to the impacts of climate variability. Being faced with increased droughts and large natural grassland areas, the herders do not know exactly how to adapt to climate change except irrigating artificial grasslands more times. Grazing households are therefore more vulnerable compared with their counterparts in the agricultural areas; 3) The major methods used by farmers and herders to adapt to climate change are digging wells, loans, and seeking other work. The respondents of the two areas take a positive approach to coping with current and future climate changes, but all the measures lead to increases in production expenditure; 4) The major barriers preventing farmers and herders from taking adaptation measures are lack of money and lack of technology and water shortage. A series of adaptation measures taken by the herders, farmers, and related government departments are less than satisfactory to deal with long-term climatic change. In the two areas, most of the respondents consider that they need more capital investment in production inputs (e.g., fodder, seeds, pesticides, fertilizer, and electricity fees), and more enrichment projects can be provided by governments, guiding people to make more money by their own efforts.

Abstract: Based on the four TM images of Naiman Banner in Inner Mongolia in 1975, 1985, 1995 and 2005, the extent and relative rate of land use change were used as the indices to analyze the regional difference of land use/cover change in the farming-pasturing zone of Naiman Banner, and the indices abundance and importance value were adopted to analyze the spatial distribution features of land use/cover change in the study area. The results showed that from 1975 to 2005, the types of land use/cover became diversified. The annual change rate was high, and the regional difference was significant. In the northern alluvial plain sub-area, woodland area increased rapidly and largely, while sandy land area decreased obviously. The changing speed of the areas of meadow and sandy land was the fastest, while that of residential area was the slowest. The main forms of land conversion were the conversion from sandy land to cropland and woodland. In the middle sandy land sub-area, sandy land had a wide distribution. The changes of other land use types were comparatively small, and the main form of land conversion was the inter-conversion between cropland and sandy land. In southern loess sub-area, cropland was the dominant land use type and had the smallest change, meadow and sandy land changed most quickly, and the conversion from meadow to cropland and woodland was the most important land conversion form. Natural factors determined the principal characteristics of land use structure in each sub-area of the study area, and artificial factors determined the changing trends of each land use type in each sub-area.
