The Natural Background Research Of Mongolian Placenames Of East Ujimqin Banner

This article studies the Mongolian placenames of East Ujimqin Banner from the perspective of geography. Analyzed the natural features,nomencla-ture, spatial distribution and the factors of evolution of Mongolian placenames, as well as the relationship between Mongolian placenames and regional culture of East Ujimqin Banner. Through research on-the Mongolian placenames of East Ujimqin Banner we can find the following regularity.Mongolian placenames of East Ujimqin Banner are like Chinese placenames, the structure is "proper name+general name ", Mongolian names are sometimes come in only proper names or only general names, General names basically reflects the landform and natural resources of East Ujimqin Banner, while, proper names fully reflect the environmental general situation, production method and lifestyle and the good wishes of the people in East Ujimqin Banner.The core content of this paper consists of three main parts:The first part mainly studies the characteristics of the placenames and their classification. The characteristics of placenames divided into two aspects in this paper which is essential characteristic and culture characteristic.Essential characteristic, including the directivity,sociality,and so on.Cultural features include universality, regionalism, nationality and stability. The naming of place names divided from two aspects of natural factors and human factors. The names named after natural factors like geographical location names, terrain place names, hydrological place names, climate place names, soil placenames, natural resources placenames and so on; The names named after human factors such as color placenames, pictographic placenames, digital placenames, the taste, the event, the morphologization placenames, sound placenames, figures and historical events placenames.The second part studies the natural geographical features of placenames. Placenames is a kind of cultural phenomenon, Not only refer to a space position which has Specific geographical entity, also reflects the local characters of natural geography and human geography. This section mainly includes placenames which reflect man-earth relationship, industrial activity of different regions, nation in spatial distribution and migration, military activities,etc.The third part mainly studies the spatial distribution situation and spatial distribution reseseah of placenames. Using ArcGIS spatial analysis software,type the data of mongolian placenames of East Ujimqin Banner in software and mapping, analyze the spatial distribution of placenames, with the increase of the density of the placenames,distribution of placenames will move from the central to the southwest and northeast,the multi-layer Agglomeration characteristics of distribution of place names is obvious.The distribution of mongolian placenames of East Ujimqin Banner transit from low density to high density gradually as a whole,At high-density areas have relatively sparse geographical distribution, At low-density areas also have high-density distribution. Compared the density map of Mongolian placenames of East Ujimqin Banner with terrain, water system, vegetation type map found that placenames distribution rend is flat, Placenames density is high the place where rivers and lakes are intensive.Through the study of placenames, reflecting the interaction strength between human activities and the geographical environment.The fourth part studies the main factors affecting naming the mongolian placenames of East Ujimqin Banner, affecting factors analyzed mainly from four aspects that is, national policy, national culture, topography, climate.
