We, Mongolians haven’t been using national script for 70 years while Inner Mongolians have been using them until the present, so we are really glad for our counterpart. Nowadays Inner Mongolian primary students are beginning to learn by Chinese language and Mongolian children in Inner Mongolia don’t study the traditional alphabet from this academic year, which is now widely discussed in Mongolian social networks. Our study goal was to define how much information does Mongolian youth, their perception about the traditional script, their point of view, their ability to reading and understanding and the ability to write correctly in the traditional script. In this study, students of the Mongolian National University of Education have participated whose age is 16~22 with a gender ratio of 79% female to 21% male ratio. 322 Students from 1st to 3rd grade who’s studying to become social worker, education study, psychology, life-long education, special needs education, Mongolian language, literature, mathematic, physics, English, Russian, physical education, ICT, sport coaching, geography, chemistry, biology and primary education teachers. We collected the data by questionnaire and literature review. Gathered information was analyzed with both quantity and quality methods. The percentage method was used for quantitative data and the logical chain method was used in the quality data method. Our study findings suggest that Mongolian youth venerate the traditional script, although their reading and understanding skills were at medium level and writing skills were insufficient. The majority of the students wish to continue learning traditional scripts. Therefore, in order to use traditional script in our everyday life, primary, secondary, high school, vocational trainings, colleges, and universities learn it continuously. Every type of advertisement, signs and billboards are required to be written in dual writing systems, in both traditional and Cyrillic alphabets.

To effectively and sustainably utilize wood resources from boreal forests in Mongolia, ana- tomical characteristics, tracheid morphology, cell proportion, annual ring width, and late- wood percentage were preliminary determined in Pinus sylvestris, Pinus sibirica, Picea obovata,andLarix sibirica trees naturally growing in Mongolia. Based on the observation, the anatomical characteristics of four common Mongolian softwoods were the same as those previously observed in the same species or the same genus species. Based on the parame- ters of the Gompertz functions for annual ring width, silvicultural management, such as thin- ning timing and harvesting age, should be considered depending on the species when the plantation is established. The results of the model selection for relationships between late- wood percentage and basic density indicated that the increase ratio of basic density corre- sponded to an increase of latewood percentage is almost the same irrespective of species, although there are species-specific values of basic density corresponding to specific late- wood percentages. The results obtained in the present study contribute effective and sus- tainable utilization of wood resources from Mongolian forestry.

Temperature Fluctuations Over the Past 2000 Years in Western Mongolia

Much of northern Asia is lacking in high-resolution palaeoclimatic data coverage. This vast region thus represents a sizeable gap in data sets used to reconstruct hemispheric-scale temperature trends for the past millennium. To improve coverage, we present a regional-scale composite of four tree-ring width records of Siberian pine and Siberian larch from temperature-sensitive alpine timber-line sites in Mongolia. The chronologies load closely in principal components analysis (PCA) with the first eigenvector accounting for over 53% of the variance from ad 1450 to 1998. The 20-year interval from 1974 to 1993 is the highest such growth period in this composite record, and 17 of the 20 highest growth years have occurred since 1946. Thus these trees, unlike those recently described at some northern sites, do not appear to have lost their temperature sensitivity, and suggest that recent decades have been some of the warmest in the past 500 years for this region. There are, however, comparable periods of inferred, local warmth for individual sites, e.g., in 1520-1580 and 1760-1790. The percent common variance between chronologies has increased through time and is highest (66.1%) in the present century. Although there are obvious differences among the individual chronologies, this result suggests a coherent signal which we consider to be related to temperature. The PCA scores show trends which strongly resemble those seen in recent temperature reconstructions for the Northern Hemisphere, very few of which included representation from Eurasia east of the Ural Mountains. The Mongolia series therefore provides independent corroboration for these reconstructions and their indications of unusual wanning during the twentieth century.
