Abstract
Based on satellite remote sensing image, GIS and Fragstats, this study modeled and calculated the dynamic changes of land use, land cover and landscape patterns in Guizhou Province, China, and calculated the changes of ecosystem service values (ESVs). The impacts of the evolution of landscape patterns on the ESVs were analyzed, and reasonable policy recommendations were made. The findings are as follows: (1) In the past two decades, the area of cropland and grassland has decreased; the area of water bodies, urban and rural, industrial and mining, and residential areas has increased; the area of forestland has increased first and then decreased. (2) The two major types of landscapes, cropland and grassland, are clearly being replaced by two land types, forest land and water bodies. (3) Overall, the degree of landscape aggregation and adjacency has decreased, and the landscape heterogeneity has increased. (4) The total amount of ESV in 2000, 2008, 2013 and 2017 was 2574 × 108 Yuan RMB, 2605 × 108 Yuan RMB, 2618 × 108 Yuan RMB and 2612 × 108 Yuan RMB, respectively. The changes of landscape patterns had important impacts on the ESVs. In order to solve the problems caused by the increasingly prominent changes in the landscape patterns and improve the ESVs, it is necessary to rationally plan and allocate land resources, optimize the industrial structures, and develop effective regulatory policies.

Summary
Land use is the long-term or regular management of land by humans based on its characteristics. Changes in land use can directly reflect the impact of humans on land resources [1]. In 1995, the International Human Dimensions Programme (IHDP) and the International Geosphere-Biosphere. Programme (IGBP) jointly released a scientific research plan for land use and land cover change, opening up a new field of research [2]. In 1999, IHDP and IGBP collaborated again and proposed the “LUCC Change Implementation Strategy” [3]. The nature of land cover in different regions of the world is mainly determined by natural factors. Due to the intensification of human resource utilization and remediation activities, land cover changes have been greatly affected [4,5,6]
