[Objective] The spatial and temporal changes in land use and ecosystem service value from 2007 to 2015 in Dongguan City

Guangdong Province

were analyzed. The aim was to determine the ecological effects of land use change and to provide a decision-making reference for sustainable use of regional land resources and ecological environmental protection.[Methods] The spatial and temporal changes in land use and ecosystem service value were analyzed using the theories and methods of land use and ecosystem service value

remote sensing

and geographic information technology.[Results] ① From 2007 to 2015

construction land in Dongguan City accounted for more than 50% of the total area of the study area

and increased continuously. The increased construction land mainly replaced cultivated land and forest land. The area with water and forest land first increased and then decreased

and the area of cultivated land and grassland decreased continuously. ② During the study period

the value of ecosystem services showed a downward trend. The total value of ecosystem services decreased by 1.97×108 yuan. The value coefficient of ecosystem services was the highest for forest land and the water area

and the profit and loss of ecosystem services fluctuated considerably. The value of forest land and water area decreased by 1.40×108 yuan in 2015. ③ From a spatial distribution perspective

the ecosystem service value of Dongguan City was centered in the central region and extended to the east and the west

forming a "high-low-high" spatial distribution pattern. The main urban area corresponded to the low-value center of the ecosystem service values of Dongguan City.[Conclusion] The land use of Dongguan City changed significantly from 2007 to 2015:the total ecosystem service value decreased

and the ecosystem service value presented heterogeneity and uneven spatial distribution.
