摘要
土地利用与城市化发展息息相关,若两者处于高度耦合优质协调状态则可促进城市社会经济的可持续发展。以呼包鄂城市群为例,计算了3个城市2001—2016年的土地利用效益与城市化综合指数、耦合协调度和灰色关联度,结果显示:①3个城市的土地利用效益与城市化水平均稳步上升,且呼包鄂土地利用效益平均增幅分别为8.96%、18.01%、24.19%,城市化平均增幅分别为9.45%、8.53%、27.71%,增幅最大的是鄂尔多斯市,包头的平均水平与增长水平都较低;②3个城市均处于高水平耦合阶段,且16a间协调度逐年递增,鄂尔多斯的增长幅度最大,为0.714 3,2009年开始3个城市均进入初级协调状态;③灰色关联度分析结果表明,呼包鄂3个城市的人口密度指标对土地利用效益的影响都是中度相关,分别为0.487 1、0.543 7、0.627 1,人口城市化是对土地利用效益影响最小的因素,所以重视土地利用的方式要远比减少人口数量更能提高土地利用的效率。
It was of practical significance for the sustainable development of urban social economy to realize the high coupling and high quality coordination between land use benefit and urbanization development level.Taking the Hohhot,Baotou and Ordos urban agglomerations as example,the results showed coupling coordination degree and grey correlation of land use efficiency and urbanization from^2001 to 2016 by calculating the comprehensiveindex:①The land use benefit and urbanization level of these three cities all increased steadily,with the biggest increase in Ordos city;whereas the average level and growth level of Baotou were both low.②All three cities were in high level of coupling stage,which increased year by year during these 16 years,with the largest growth in Ordos.All three cities entered the primary coordination state from^2009.③The results of grey correlation degree showed that the impact of population density on land use benefit was moderately correlated in three cities.Population urbanization was the least influential factor on land use benefit.Therefore,paying attention to land use pattern was far more effective than reducing the number of population.
