Abstract：Water conservancy projects serve as a critical nexus between human society and natural water resource uti⁃
lization，with their construction and operational management being intrinsically linked to the realization of watershed

ecosystem service values. This paper aims to systematically investigate the connotation and key elements of ecological
service values in water conservancy projects，establish a scientific value quantification system，and explore pathways

for value realization and optimization. Guided by the methodological framework of “theoretical analysis-system

construction-method selection-value realization”，and based on the classification and functional characteristics of

water conservancy projects，this research integrates multidisciplinary theories and methods to achieve the following
objectives：1）develop a multidimensional ecological value quantification system through systematic investigation of

value connotations and elemental characteristics；2）conduct spatiotemporal heterogeneity analysis of ecosystem ser⁃

vice value，establishing an accessibility assessment framework for enhancing value realization；and 3）optimize value

realization pathways through systematic refinement. The findings reveal the spatial distribution patterns and driving

mechanisms of ecological service values in water conservancy projects，providing theoretical foundations and method⁃
ological support for enhancing watershed ecosystem service values.

Keywords：ecosystem service value of water conservancy projects；value calculation system；spatial-temporal het⁃

erogeneity；value realization
