چکیده
The water conservation function of ecosystems is a research hot spot in the field resources, and it also an important ecological service terrestrial key point eco-hydrology research. With increasing frequency human activities climate change, how to reveal response ecosystem changing environment scientific problem that needs be urgently addressed hydrology To eco-hydrological processes under environment, this study was based on distributed hydrological model (SWAT) used amount (WCA) as indicator assess capacity ecosystems. Scenario analysis statistical were determine spatial temporal evolution WCAs farmland, forest, grassland further investigate influence mechanisms land use change WCA. findings show (1) conditions Hanjiang watershed have determined distribution pattern ecosystem’s patterns WCA each differed significantly between dry season wet season. Under combined there no significant (2) Climate patterns, which dominated by precipitation influenced evapotranspiration, changes In addition, differences environments Differences type local main reasons for such differences. (3) There among Forest had highest WCA; most sensitive change. This can provide theoretical basis alleviating increasingly serious resource problems basin ensuring security basin.
