Referenced sub-drainage basins were selected in the upper reaches of the Madao main river way, and topographic parameters were obtained using software of River Tools in each sub-drainage. Monthly runoff simulations were then applied to them with the same parameters as Madao catchment, the responses of runoff simulation to topographic parameters were studied, and the Normalization of Runoff-total Length Index were presented. Analyses indicate that NRLI is influenced by source density. NRLI fluctuates tempestuously as source density decreases sharply.
