Abstract:: By runoff determination,the regional vegetation and habitat survey,we integrate ecohydrologidal parameters measured in a small-scale and ecological changes in environment.We used the RS and GIS technology and hydrological analysis methods in the research.We reveal the distribute pattern and change of the surface runoff in typical steppe of Inner Mongolia from the late 1970s to the beginning of 21th century.Resorting to this method,preliminary conclusions are as follows:(1) The surface runoff is between 0~1 mm in late 1970s and late 1980s and is between 1~2 mm in the beginning of 21th century in most of the study area.The largest area of surface runoff all appear in the southwest of Abaga Banner in three periods,and the minimum area appear in the near the border and Huitengliang.(2)The total volume of the average runoff of study area increases continually in the growing season in nearly 30 years.The total volume of the average runoff is 4.22 × 10⁷ m³ and 4.87 × 10⁷ m³ in late 1970s and late 1980s respectively and increases significantly to 7.46 × 10⁷ m³ in the beginning of 21th century.
