\begin{abstract}
The rapid urbanization has caused changes in climate and environment and
threatened the ecosystem with multiple risks. The ecological service
capacity has shown a downward trend accordingly. It is significant to
explore the spatio-temporal evolution of land use and ecological service
value in mountainous counties at small scales, as it coordinates
economic growth and ecological protection, and promotes sustainable and
high-quality development. Based on the SD-PLUS model, taking Qianshan
city as an example, the study simulated three scenarios of land use
change: ecological protection, coordinated development, and economic
priority, and studied the impacts of land use change on the value of
ecosystem services. Results showed that:  Under the three scenarios,
the construction land in the study area increased significantly, the
forest and water area have a decreasing trend, and the scale of gardens
has partly increased.  Construction land expands in clusters in the
urban built-up areas and dots in mountainous areas; land use changes are
primarily affected by roads, followed by areas where artificial
facilities are relatively sparse, and DEM has the greatest impact on
land use changes.  The overall ecosystem service value shows a downward
trend, with the comprehensive coordination type dropping the least
(8.79\%). The value distribution changes little at space scale, and
different regions demonstrate different degrees of changes. From the
perspective of value type, the service values of climate regulation and
water conservation are significantly reduced, while that of food
production is relatively stable; and from the perspective of various
lands with their ecological service values, cultivated land and forest
remain stable. The study results can provide technical ideas for the
coordinated economic development and ecological protection of
mountainous cities, and boost the implementation of green development.%
