摘　　要：近20年来成都市经历了快速的城市化进程,其国土空间格局发生了剧烈变化。研究国土空间格局的时空演变,对成都市高质量发展具有重要意义。本文基于Landsat系列卫星影像和土地利用/覆盖数据集,调查了成都有关生产、生活和生态用地的土地功能变化。后采用土地动态度、景观格局指数和Pearson相关系数等方法,分析了成都景观格局的节奏空间演变,并提出了一些建议。结果表明,成都市PLE用地动态程度严重,生产用地和生态用地面积在2015年之前有所减少;2015年后动态程度有所下降,2000–2019年动态程度较高的地区开始向东北移动。生产用地的变化是影响成都景观格局的主要因素。综上,本研究提出了支撑成都高质量发展的"一核、两带、四区、一方向"的宏观发展战略和建议。Chengdu has experienced a rapid urbanization in the past two decades,and its land spatial pattern has undergone severe changes.It’s meaningful to investigate the tempo-spatial evolution of land spatial pattern and then contribute to high-quality development in Chengdu.Based on the Landsat-series satellite imagery and land use/cover datasets,this paper investigates Chengdu’s land function change concerning Production,Living and Ecological(PLE)land.The methods of land dynamics degree,landscape pattern index and Pearson correlation were be employed to analyzes the tempo-spatial evolution of landscape pattern in Chengdu,and some suggestions were finally made.We found that there were severe dynamic degree of PLE land in Chengdu and the production and ecological land were decrease obviously before 2015.Contrastingly,the dynamic degree is decrease after 2015,high dynamic degree regions are move to the northeast from 2000–2019.In addition,the change of production land is the main factor affecting the landscape pattern of Chengdu.In general,we put forward the macroscopic strategy and suggestions of“one core,two belts,four regions,and one direction”to support the high-quality development of Chengdu.
