森林火灾属于突发性较强、破坏性较大、处置救助较为困难的自然灾害。本文以2006年5月25日大兴安岭森林火灾为例,在利用时间分辨率较高的MODIS归一化植被指数(NDVI)、中红外波段(第22波段)和热红外波段(第32波段)准确辨识火灾发生点的... 详细信息

森林火灾属于突发性较强、破坏性较大、处置救助较为困难的自然灾害。本文以2006年5月25日大兴安岭森林火灾为例,在利用时间分辨率较高的MODIS归一化植被指数(NDVI)、中红外波段(第22波段)和热红外波段(第32波段)准确辨识火灾发生点的基础上,结合相对较高分辨率的TM数据计算了火灾发生面积。结果表明,由于MODIS数据的时间分辨率高和波段多的优势,能较准确地辨识了森林火点及其蔓延趋势。用相对高分辨率的TM数据来计算的此次森林火灾发生面积约为312km2,对该地区森林和草原生态系统及人类财产带来了巨大的损失。

蒙古国南部是沙尘暴频发地区,其产生主要由蒙古国西部的山体地形和从西部吹来的盛行风所引起的。本文选取位于戈壁阿尔泰盟相近的2个观测站点,采用2004-2013年3-5月份的气象数据,对沙尘暴发生日数及其风速、风向、降水和温度进行了对比... 详细信息

蒙古国南部是沙尘暴频发地区,其产生主要由蒙古国西部的山体地形和从西部吹来的盛行风所引起的。本文选取位于戈壁阿尔泰盟相近的2个观测站点,采用2004-2013年3-5月份的气象数据,对沙尘暴发生日数及其风速、风向、降水和温度进行了对比。得出结果显示:Tooroi站的沙尘暴发生日数明显大于Aibogd站,并Tooroi站的春季气温较高,降水量较少,风速较大。从山体结构而来的气旋,可能是除气象因素之外造成以上结果的因素之一。

This paper develops a large-scale small-gain result for dynamic networks composed of infinite-dimensional subsystems. It is assumed that the subsystems are input-to-output stable（IOS）and unboundedness observable（UO）, and the large-scale infinite-dimensional system can be proved to be IOS and UO if the proposed small-gain condition is satisfied.

This study presents thermokarst lake changes at seven different sites in the continuous and isolated permafrost zones in Mongolia. Lakes larger than 0.1 ha were analyzed using Corona KH-4, KH-4A and KH-4B (1962-1968), Landsat ETM + (1999-2001), and ALOS/AVNIR-2 (2006-2007) satellite imagery. Between 1962 and 2007, the total number and area of lakes increased by +21% (347 to 420), and +7% (3680 ha to 3936 ha) in the continuous permafrost zone, respectively. These changes correspond to the appearance of 85 new lakes (166 ha) during the last 45 years. In contrast, lakes in the isolated permafrost zone have decreased by –42% (118 to 68) in number and –12% (422 ha to 371 ha) in area from 1962 to 2007. The changes in lake area and number are likely attributed to shifts in climate regimes and local permafrost conditions. Since 1962, the mean annual air temperature and potential evapotranspiration have increased significantly in the northern continuous permafrost zone compared to the southern isolated permafrost zone. Due to ongoing atmospheric warming without any significant trend in annual precipitation, patches of ice-rich subsurface have thawed, and the number and area of lakes have accordingly developed in the continuous permafrost zone. Shrinking of thermokarst lakes in the isolated permafrost zone may be due to disappearing permafrost, deepening of the active layer, and increased water loss through surface evaporation and subsurface drainage.

The wild camel (Camelus ferus) is a critically endangered large ungulate, surviving in just three distinct populations located in the Taklamakan Desert, China;deserts near Lop Nuur, China;and in China and Mongolia within and adjacent to Mongolia’s Great Gobi Strictly Protected Area (GGSPA). The population surviving in Mongolia remains poorly researched, but as few as 500 individuals may survive, although its distribution has remained relatively constant over the past 30 - 50 years. This study aimed at identifying potentially important environmental factors that influence the distribution of wild camels in Mongolia and predicting seasonal movement. We predicted distribution by season using presence only data and selected environmental predictors, including land surface temperature, normalized difference vegetation indices (NDVI), water sources, vegetation and soil. Model predictions revealed that land surface temperature in summer correlated significantly with wild camel distribution, with camels occurring in cooler areas. Abundance of biomass did not significantly correlate with camel distribution. Camels occurred in areas with intermediate levels of NDVI in most seasons, implying that they may base foraging decisions on forage quantity, not quality. Positive correlations of camel distribution with higher NDVI in summer (P = 0.03) suggests that they may prefer herbaceous species that appear after rainfall. Models indicate distance to water sources may be critical for camel distribution in all seasons. Camel occurrence correlated with areas containing shallow mountain soils in summer. Camels displayed no significant habitat correlations in other seasons, yet ranges differed among all seasons. Camels used a common region in spring, summer and autumn that we believe represents the core of the species’ annual range. Wild camel distribution during winter varied significantly from other seasons. Our modelling led to a predicted distribution range that was consistent with

The present study focuses on the Lower Cretaceous Khukhteeg Formation (Central Mongolia), which yields palynological assemblage that is used to understand the paleoclimate. Palynology samples from the Khovil opencast mine Choir-Nyalga Basin in the Central Mongolia have been analyzed for palynomorphs with SEM. The assemblage is dominated by pollen to conifers, such as Pinaceae, Podocarpaceae and Taxodiaceae, indicating the vegetation of conifer forests. The assemblage contains abundant spores Schizaeaceae, Cyatheaceae, which are generally associated with wet habitats. According to the detailed analyses, the plant community indicates that warm and humid subtropical paleoclimate controlled the study area during the Early Cretaceous.
