摘要
随着城市化水平的不断提高,城市空间扩张成为必然趋势,合理控制城市空间扩张规模成为社会关注的热点。以乌鲁木齐2000―2017年宏观政策、社会经济、人口规模、居民生活水平和交通环境方面的数据为依据,选取相关指标进行城市扩张强度分析和Lasso压缩变量构建模型研究城市建设用地扩张驱动因素。结果表明:乌鲁木齐城市建设用地面积呈逐年增加的态势,17年扩张了3倍多,扩张速度与扩张强度均是先增后减的趋势,最大值出现在2004―2008年这一时期;宏观政策对于城市空间扩张具有引导作用,由于受地理位置限制城市规划提出“南控、北扩、西延、东进”的战略;社会经济、居民生活水平和交通环境方面的部分指标对于城市空间扩张具有推动作用,其中,人均GDP、第三产业增加值和人均拥有道路面积是影响城市空间扩张的主要驱动力,其次是城镇单位在岗职工平均工资、城市公园绿地面积和社会消费品零售总额。因此,乌鲁木齐城市空间合理扩张与政策、经济和环境密不可分。
With the continuous improvement of urbanization level,urban spatial expansion has become an inevitable trend,and the reasonable control of scale of it has become a hot topic of social concern.Based on the data of Urumqi′s macro policy,social economy,population size,residents′living standard and traffic environment from 2000 to 2017,this paper selects relevant indicators to analyze urban expansion intensity and construct lasso compression variable model to study the driving factors of urban construction land expansion.The results show that:the area of urban construction land in Urumqi is increasing year by year,and it has expanded more than three times in 17 years.The expansion speed and expansion intensity are both increasing first and then decreasing,and the maximum value appears in the period of 2004-2008.The macro policy plays a guiding role in the urban spatial expansion.Due to the geographical constraints,the urban planning proposes"Control in South,Expansion in North,Extension in West,Advance in East".Among them,the per capita GDP,the added value of the tertiary industry and the per capita Road area are the main driving forces affecting the urban spatial expansion,followed by the average wages of urban employees,the green area of urban parks and the total retail sales of social consumer goods.Therefore,the reasonable expansion of urban space in Urumqi is closely related to policy,economy and environment.
