| The population refers to a certain quantity and quality of people living in a particular social system, and it is as well as a constant research topic of "man-land relationship", which is an important part of geography. With the rapid development of social and economic-the contradiction between people and places is increasingly prominent a variety of ecological environment problems have been appeared in today’s world. In recent years, contradictions between resources, ecological environment and population are very prominent, there have been a shortage of resources, severe environmental degradation and other phenomena that affect regional and the world is social and economic development. Pastoral has economic and political status in location, natural conditions, and economic development. Many of farming counties have vast area, rare population, rich mineral resources, simultaneously, its ecological environment is very fragile, Shilin Gol League livestock counties is a group that have distinctive characteristics in this area is economy, by virtue of its unique grassland, mineral, energy and other natural resources, become a bright spot of social and economic development in Inner Mongolia.Population in any region is not evenly distributed, overlay, fusion analysis can not be generate between the demographic data based on administrative divisions and Natural Environmental Data based on geographical unit, and the traditional population data distribution exists regional abrupt, which is does not meet the actual population distribution. Currently with the rapid growth of3s technology, the traditional population data statistical methods which based on administrative boundaries has shown its many limitations in theory or in practice. Select the Shilin Gol League livestock counties as the spatial object, the author study area was the Shilin Gol League livestock counties where was abound with mineral resources and has fragile ecological environment, make a choice that fit this study area is indicator system and make sure the weights of each index, investigate the spatialization of population density. In this paper, promote the use of type, the main rivers, the main roads are main factors of population density distribution., distribution of pastoral settlements is the direct instruction factor of population density distribution, through the GIS platform and multi-factor fusion, we have got the population density distribution of this study area, simultaneously, we attempt to reveal the evolution mechanism of pastoral population density, the study on spatial distribution of population density in pastoral areas is the guide and basic of further space simulation of economic and social data, And pastoral areas is a very unstable, extremely fragile ecosystems, the study of the actual distribution of the population in pastoral areas and population carrying capacity, optimizing regulation of pastoral population density distribution has a significance on socio-economic development and ecological balance in pastoral areas. |
