%X Hydrological simulation for the Salt Lake basin encounters many difficulties by using traditional methods due to the lack of basic data.An air-space-ground stereoscopic monitoring system for the Salt Lake was established using satellite remote sensing technology,unmanned ships and other technologies to study the changes of ecological environment and hydrometeorology.The water level-area-volume relationship curve was obtained,the monthly-scale lake area was interpreted through monthly remote sensing data,and the storage variable as well as the monthly-scale runoff into the lake were deduced.Furthermore,a VIC(Variable Infiltration Capacity)model based on multi-source data was constructed to simulate the lake runoff by collecting and sorting out the Chinese regional ground meteorological element-driven data set CMFD and MODIS LAI(leaf area index).Results reveal that the Nash coefficient NSE and relative error of the simulated runoff of the Salt Lake basin are 0.87 and 11.81%,respectively,which reflects the change of the actual runoff.The air-space-ground stereo monitoring system combined with the VIC model could simulate the monthly-scale runoff change process of the Salt Lake basin,and hence offering reference for the hydrological simulation of rivers and lakes in areas with no data.
