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.
