Impacts of Historical Land Use Changes on Ecosystem Services in Guangdong Province, China

Assessing land use change and its impacts on ecosystem services is of great significance for optimizing management enhancing sustainability. This study explores changes their five typical services, namely grain production (GP), water yield (WY), soil conservation (SC), habitat quality (HQ), carbon sequestration (CS), during 1990–2020 using the Integrated Valuation Ecosystem Services Trade-offs (InVEST) model in Guangdong province, which has experienced substantial change. During period, cultivated land, forest grassland, areas, built-up unused correspondingly had changed by ?10.7%, ?1.9%, ?5.1%, 13.7%, 97.9%, ?38.8%. For GP, SC, HQ averagely decreased ?8.66% (?12.3 t·km?2), ?0.02% (?2 and?2.74% (?0.02), respectively, while WY CS increased 3.10% (22 mm) 20.70% (515 respectively. Land that greatest average negative WY, HQ, were to (?150.9 areas (?1072 mm), grassland (?10,166 (?0.65), (?2974 t·km?2) positive (78.8 (943 (3552 (0.40), (3338 The results indicated a significant impact services.
