ABSTRACT: In recent years, with the high attention paid to the protection and development of ecological environment, Assessing the spatio-temporal evolution of ecosystem service functions has become a hot topic. Liaoning Province is one of the traditional industrial bases in China. With the rapid development of economy, the ecological system is also facing the challenges of desertification and soil erosion. Therefore, this study took Liaoning Province as the main research object. Based on land use, climate and soil data from 2000, 2010 and 2020, the InVEST model was used to select indicators and analyze the spatio-temporal evolution of ecosystem service functions in Liaoning Province from two functions: water production and carbon sequestration, so as to provide support for the ecological environment protection and development of Liaoning Province. The results show that: 1) Over the course of the past two decades, water resources supply in Liaoning Province increased first and then decreased, showing a significant trend of decreasing from the eastern mountains to the western hills. 2) Carbon storage in Liaoning Province showed a slow and steady upward trend in twenty years, and in spatial scale, carbon sequestration storage showed a gradually decreasing trend from the east and west sides of Liaoning Province to the middle part of Liaoning Province. The analysis of temporal and spatial evolution characteristics of water production, carbon storage, in Liaoning Province can provide support and reference for ecological environment protection and development in Liaoning Province.
