The Study On The Coordinated Development Of Population, Economy And Envieonment Based On Land Use Change

In this paper, we using ArcGIS, Fragstats and SPSS to study land use change in Xilingol League. I selected the TM remote sensing data of 2000,2004 and 2010. Combining with Inner Mongolia statistical yearbook and field investigation data, I take analysis on the land use change, the landscape index, the land use degree and coordination degree of the population, the economic and the environment. At last take the analysis of the driving force. The result shows that:(1)The grass is the dominate part of Xilingol League land use types. It takes more than 80% of the area in the study area. The grassland has degradation trends, the decreasing number is 10768.83km2. First of all, the grass turned out for the farmland and the number is 2486.19 km2 and 2666.08 km2, town land and the number is 12.57 km2 and 20.11 km2, rural residential areas and the number is 84.00 km2, mining and traffic land and the number is 0.45km2 and 64.14km2, saline-alkali land and sand and the number is 10241.84km2 and 1391.92km2. Secondly, the higher coverage grassland turned into a lower coverage grassland. Learn from the landscape transition matrix between 2004 and 2010. The number high coverage grassland Conversed to middle and low coverage grassland is 7790.48 km2, and there is 12.13 km2 grassland switched into high coverage grassland. The number middle coverage grassland Conversed to low coverage grassland and high coverage grassland are 4916.48 km2 and 0. The low coverage grassland did not roll out the land area.(2) The influence of human is increasing. But due to its low starting point, the performance is not outstanding. We can see that the influence of human activities on land use is gradually enhanced from the growth trend of farmland, town land, rural residential areas and mining and traffic land, and the trend of the development of population, the economic and government policy.(3) From the coordination degree study of the study area we can found that the coordination degree is at a medium level. The coordination degree from 2003 to 2009 is 0.70,0.70,0.77,0.74,0.88,0.77,0.70. And coordination degree is in decline after 2007 (0.88-.068). The reason restrict the coordinated development is the population, and the environment in which also played a certain effect.(4) The driving force of land use change is temperature, precipitation, demographic factors, economic factors and government policy. The main factor of land use change is economic factors and government policy.
