This paper proposes an estimating method of daily stream flow by using the AutoCAD according to Fractal Theory, and then,taking the four gauging stations of the Malian River as examples,calculates the fractal dimensions of the daily stream flow of four gauging stations.

Digital terrain analysis of Malian River Basin based on DEM;

The comprehensive post-assessment of Heihe River project on the ecological environment is necessary to the sustainable development of the whole Northwest China The comprehensive assessment by applying AHP￠success assessment and fuzzy comprehensive assessment may overcome the subjectivity of the traditional qualitative assessment and a more objective and more scientific conclusion may be got.
