摘要： Changes in land use significantly affect the environment by disrupting the natural landscape patterns. These changes may alter the ecological processes that affect the flow and provision of ecosystem services. In this study, we quantified land-use changes and the effects of landscape patterns on estimated Ecosystem Service Values (ESVs) at spatial and temporal scales in Ghana for four different years: 1995, 2005, 2015, and 2020. Using Fragstats spatial software, we computed landscape metrics to calculate the landscape patterns of the study area. We established a relationship between ecosystem services and landscape patterns by using correlation and regression analyses. The dominant land use in Ghana found in decreasing order were agriculture, forest, and savannah. The proportions covered by settlement and bare land were relatively small. The estimated ESVs for the study periods were US$172.11 billion in 1995, US$166.38 billion in 2005, US $166.07 billion in 2015 and US$166.59 in 2020. The entire decline observed was very significant (US$5.52 billion) because of the huge reduction in wetlands during this period. Linear multiple regression and correlation analyses revealed the relationships between ecosystem services and landscape patterns. According to the regression models, the landscape metrics of landscape composition and configuration had a net effect on the individual ecosystem services. This study provides useful reference material for land use policy makers, managers, and institutions involved in the implementation of policies and conservation practices to enhance the provision of ecosystem services.
