摘要：

Drought risk to climate change in Laohahe River Basin located in semi-arid of northeast China assessed by applying Soil Moisture Index (SMI) in sub-basins scale were simulated by defining scenarios for changes in climatic inputs to SWAT. The results indicate that in most sub-basins, SMI is very sensitive to climate change. Precipitation shifts would have a greater impact on SMI, as compared with temperature. Dry and warm climate increased drought risk obviously. The northern sub-basins were more sensitive and in relative stronger risk. Drought risk was smaller in forestland than in agricultural areas.
