Abstract:[Objective] The change trend in land-use patterns of a port city during rapid urbanization was studied to provide a scientific basis for local land-use planning.[Methods] This research used five remote sensing images of Kuala Lumpur, Malaysia (for 2000, 2005, 2010, 2015, and 2020) as the source data. The index classification method was used to extract land-use information based on the interactive data language (IDL), and RS and GIS technology along with landscape ecology methods were used to study the change of the land-use landscape pattern of Kuala Lumpur from 2000 to 2020. Finally, the grey prediction model was used to predict land-use data for Kuala Lumpur in 2025.[Results] From 2000 to 2020, Kuala Lumpur's plantation and forest land decreased significantly, whereas construction land increased rapidly; plantations in the central part of the port and in the city circle were mainly converted into construction lands. The landscape shape of land use tended to be complex and irregular, the spatial connectivity of landscape types was reduced, and the landscape heterogeneity was enhanced. The estimated areas of construction land and plantation in Kuala Lumpur in 2025 were 1624.12 km2 and 2216.99 km2, respectively. Compared with previous years, the area of construction land will increase and the area of plantations will decrease.[Conclusion] In 2025, the main land-use type in Kuala Lumpur will still be plantation. From a macro perspective, with the rapid development of cities, the number of plantations will continue to decrease. Future development plans need to rationally plan land-use patterns, improve land-use efficiency, and strengthen the protection of plantations.
