【摘要】：基于南疆地区1989—2012年的社会,经济统计数据应用一元线性回归模型和协调度分析法,采用1990年,2000年,2010年3期Landsat TM,ETM+、ALOS/AVNIR-2数据作为数据源,提取城市和耕地面积信息,分析南疆地区城市化水平和耕地资源的变动情况、相关性以及协调性,找出城市化水平和耕地资源的互动关系,有助于为当地政府城市规划和进一步发展提供参考依据。结果表明:(1)近24a南疆地区处于城市化较慢的发展时期,其中城市化水平最高的是库尔勒市,较高的有阿克苏市、喀什市、和田市,最低的是阿图什市;(2)库尔勒、阿克苏、喀什等城市的耕地面积出现增长趋势,阿图什市和和田市耕地面积呈递减趋势;(3)1989—2012年南疆地区耕地资源与城市化水平的协调关系逐渐向良性发展,从1990年的不协调变了2012年的基本协调,说明研究期间南疆地区城市化水平与耕地资源协调度各年份的变化均不一致。
[Abstract]:Based on the social and economic statistics of the southern Xinjiang from 1989 to 2012, the linear regression model and the degree of coordination analysis were used to extract the urban and cultivated land area information from the three issues of Landsat TMM-ETM / ALOS / AVNIR-2 on 1990, 2000 and 2010. This paper analyzes the changes of urbanization level and cultivated land resources in southern Xinjiang, and finds out the interactive relationship between urbanization level and cultivated land resources. The results show that the southern Xinjiang region is in a slower period of urbanization in the past 24 years, of which the highest level of urbanization is in Korla City, and the higher one is Aksu City. Kashgar City, Hotan City, the lowest of which is Atush City, No. 2) Kurla, Aksu, Kashi and other cities have an increasing trend of cultivated land area. The cultivated land area in Atushi and Hotan cities showed a decreasing trend from 1989 to 2012, the harmonious relationship between cultivated land resources and urbanization level in southern Xinjiang gradually developed to a benign development, which changed from the disharmony in 1990 to the basic coordination in 2012. During the study period, the urbanization level and the degree of coordination of cultivated land resources in southern Xinjiang were not consistent with each year.
