Abstract：Eco-hydrological division is an important basis for watershed ecological protection and water envi⁃
ronment management. The watershed in the rapid topographic change basin on the eastern Tibetan Plateau
is one of the typical areas for eco-hydrological zoning research. Based on the ecological hydrological mutual
feed-back mechanism，an evaluation index system of eco-hydrological division is constructed，with 12 indi⁃
cators from four aspects of topography，climatic characteristics，ecological background and human activities，
which can comprehensively reflect the entire chain of hydrology-soil-climate-ecosystem in a river basin
with rapidly changing terrain. Taking the Dadu River Basin as an example，this paper quantified the ecolog⁃
ical hydrological index value of the basin，extracted small watersheds based on the SWAT model，and de⁃
scribed the regional ecological hydrological division pattern；Through the analysis of the superposition of eco⁃
logical hydrological divisions and land use types， nature reserves and ecological redlines， a scientific basis
for the development， utilization， protection and ecological regulation of watershed resources was provided.
Based on the value of the ecological hydrological index and the extraction of 384 small watersheds， three
types of zones were delineated，the less water ecological zone，the water balanced ecological zone，and the
multi-water ecological zone. The delimitation results were in good agreement with land use types，nature re⁃
serves and ecological red lines. Attention should be paid to the ratio of production and living spaces in
less water ecological areas，to coordinate the contradiction and balance between production and living water
and ecological water demand，and to serve the land and space planning of the river basin.
Keywords：eco-hydrological division；rapid topographic change basin；nature reserves；ecological red line；
eastern Tibetan Plateau
