喀什市城市化发展与建设用地结构变化之间的关联性

Correlation Between Urbanization and Construction Land Use Change in Kashgar City

[目的] 分析城市化与建设用地结构变化之间的关联性，为城市长期可持续发展提供一定的科学依据。[方法] 用2009-2013年统计数据，先用相关统计法分析喀什市城市化与建设用地结构变化的一般特点和变化趋势，在此基础上，用灰色关联法分析其相互关联性。[结果] 研究时段内3种建设用地类型发生了较明显的变化，其中城镇村及工矿用地所占比重始终占最大优势；城市化与建设用地结构变化之间有显著的关联性，非农业人口比重、人均GDP、建成区面积和人均日生活用水量等指标与建设用地之间的关联度都在0.65～0.85之间，属于强关联，人均公园绿地面积的关联度在0.35～0.65之间，属于中度关联；城市化指标与建设用地指标之间有较强的相互关联性，平均关联系数都大于0.65。[结论] 喀什市城市化与建设用地结构变化之间存在着较强的关联性。合理调整人口结构和规模，统筹兼顾人口、经济、空间、社会、环境城市化发展，有效并合理利用有限资源并优化配置土地资源等是喀什市可持续发展的有效措施。

[Objective] The objective of this study is to analyze the relationships between the urbanization and urban construction land use in Kashgar City in Xinjiang Uygur Autonomous Region, in order to provide a scientific basis for long-term sustainable development.[Methods] Based on the statistical data, we analyzed the characteristics of urbanization and construction land use changes in Kashgar City, and examined the relationship between them during the period from 2009 to 2013 by using Grey relation analysis method.[Results] The changes of construction land use were obvious, and the ratio of town-village and industrial-mining land was the biggest in total land area. There was a significant relationship between urbanization and construction land use. The average correlation coefficient between non-agriculture population proportion, per capita GDP, urban built-up area, daily water consumption per capita and construction land were ranged from 0.65 to 0.85, which belongs to the strong correlation. The correlation coefficient between per capita park green space and construction land was about 0.35 to 0.65, and it was a moderate correlation. There was a strong correlation in the two-way average correlation coefficient values between urbanization and construction land use and they were greater than 0.65.[Conclusion] There is a strong correlation between the urbanization and urban construction land use in Kashgar City. Reasonable adjustment of population structure and size, balancing development of population, economy, space, society and environment, effective and reasonable use of limited resources and optimal distribution of land resources are the effective measures for sustainable development of Kashgar City.
