利用地理省情监测数据分析土地利用变化——以济南市东部老工业区为例

传统的土地利用变化分析方法无法进行大规模、长周期的土地动态变化监测,也无法适应城市日新月异的发展需求。本文利用山东省地理省情监测数据,采用多种土地利用指数模型对济南市东部老工业区的土地利用变化情况进行了研究。这些指数模型包括动态度、转移矩阵、多度、重要度等。本文通过定量分析2017—2019年老工业区各土地类型的空间格局演变过程,揭示其土地利用空间格局演化机理,并结合社会经济发展的相关资料,对发生变化的原因和内在驱动力作了合理的解释和说明,为新型城镇化政策制定提供了切实的数据支撑和决策依据。

Analysis of land use change based on geographical provincial condition monitoring: taking old industrial zone in the east of Jinan as an example

The traditional land use change analysis method can not satisfy the demand of large-scale and long-cycle dynamic land change monitoring, which also can not adapt rapid development demand of the city. Based on the monitoring data of Shandong geographical provincial condition, this paper studies the land use change of the old industrial area in the east of Jinan by using various land use index models. These index models include dynamic degree, transition matrix, frequency degree, importance degree, etc. Through the quantitative analysis of the evolution of the spatial pattern of various land types in the old industrial zone from 2017 to 2019, this paper reveals the evolution mechanism of the spatial pattern of land use, combined with the relevant data of social and economic development, this paper also makes a reasonable explanation on the causes and internal driving force of the change, which provides practical data support and decision-making basis for the formulation of new urbanization policies.
