Abstract:

In this paper, the coupling and coordination relationship between urbanization and intensive utilization of cultivated land in Aksu City, Xinjiang was studied using the entropy method, multi-objective linear weighted function method and coordination degree model based on the statistical data from 1990 to 2015. The results are as follows: ①The urbanization level in Aksu was significantly improved in the research period, and the score of urbanization level was increased from 0.046 in 1990 to 0.330 in 2015, but the overall level was not high. The development speed of urbanization level was different in different periods. It was developed slowly from 1990 to 2004 and stepped into the rapid development stage in 2005. The economic urbanization level and social urbanization level were higher, the population urbanization level was lower than other urbanization levels, and the economic urbanization dominated the total urbanization in Aksu; ② The overall intensive utilization level of cultivated land was low. In the study period, it was in a slow growth at first and then in a slow downward trend. From 1990 to 2009, the intensive utilization level of cultivated land was unchanged at first and then increased slowly with score of 0.129-0.193. From 2010 to 2015, the score was decreased slowly in a range from 0.191 to 0.167. The level of social input and the utilization efficiency and sustainability of cultivated land was fluctuated significantly. After 2008, the cultivated land area was enlarged substantially, resulting in a downward trend of intensive utilization of cultivated land in the later study period; ③The coordination degree between urbanization level and intensive utilization level of cultivated land was increased at first and then decreased, the coordination degree was developed from a mild maladjustment in 1990 to a high-quality coordination in 2011, and it was dropped to a serious maladjustment during 2012-2015. The coordinated development degree was increased from 0.42 in 1990 to 0.78 in 2012, but decreased to 0.75 during 2013-2015. The coordination development level was changed from a serious maladjustment in 1990 to a moderate one in 2015, a retarded type of urbanization occurred during1990-2010, and a retarded type of intensive utilization of cultivated land appeared during 2011-2015.
