Abstract

This paper selected the soil erosion, land desertization, bio-inhabitation as sensitive factor to research eco-environmental sensitivity spatial distribution characteristics of the Xilingol Grassland. (1)slight sensitivity is the main level of soil erosion sensitivity, which mainly distributes in the flat terrain of the plain area. Moderately sensitive area is distributed in mountainous and hilly areas.(2)In-sensitive and slight sensitive areas of desertification accounted for 0.004% and 3.186% of the total area, respectively, and the proportion of moderately sensitive area was 46.533%, and highly sensitive area mainly distributed in the Hunshandake sandy land, where vegetation relatively sparse, and sand is the main soil type, and the sandstorm weather often happened. Sonid right and Sonid left banner is extreme sensitive area.(3)Bio-inha- bitation sensitive level has a downward trend from southeast to northwest, highly sensitive areas distributed in the mountainous areas with high vegetation coverage and abundant rainfall. (4)Eco-environmental sensitive index is between 1.50935-5.57577 in Xilingol grassland, where the main sensitivity type is slight sensitivity, moderately sensitive areas distributed in Sonid right banner, Sonid left banner, Boarder Yellow banner, Abagaqi, west ujimqin and Xilinhot.
