As the beginning of this thesis, the important meanings of sea ice to global climate change and ocean engineering in polar and subpolar sea regions are explained firstly. Then, it is pointed out that sea ice numerical modelling, as a powerful tool of sea ice research, is limited by the precision of parameters within models instead of itself so far. It is meaningful to study the important parameters of sea ice dynamics by means of the rapidly developing digital imaging techniques so as to provide better input parameters needed in numerical models.

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.
