SpatialTemporal Differentiation and its Causes of Land Use Change from 2011 to 2020 in Changqing District in Ji'nan City

摘要:

研究城市土地利用时空变化特征及驱动因素对城市促进合理利用土地资源、生态—社会—经济可持续发展具有重要意义。本研究运用ArcGIS定量提取土地利用数据，建立土地利用变化幅度模型和土地利用变化程度模型，分析长清区2011—2020年土地利用时空变化特征；选取8个社会经济驱动因子，利用皮尔逊相关系数法研究土地利用变化的社会经济驱动机制。结果表明，2017年后长清区土地利用处于调整阶段，应优化土地利用规划，提升土地利用社会—经济—生态综合效益。

Abstract:

Studying the spatiotemporal changes and driving factors of urban land use is of great significance for promoting the rational use of land resources and sustainable ecological, social, and economic development in cities. By using ArcGIS, land use data has been to quantitatively extracted, a land use change amplitude model and a land use change degree model have been established, and the spatiotemporal changes in land use in Changqing district from 2011 to 2020 has been analyzed. Selecting 8 social and economic driving factors, by using Pearson correlation coefficient method, social and economic driving mechanism of land use change has been studied. It is indicated that land use in Changqing district is in the adjustment stage after 2017, and land use planning should be optimized to enhance social economic ecological comprehensive benefits of land use.
