| Research Abstract |
The distribution of AI on the area of natural forest and natural grass-land is significant difference in the distribution of AI between natural forest and natural grass-land, though there is no difference in the distribution of WI. In conclusion, transition of vegetation from forest to grass is caused by aridity level in Shaanxii area. In the transition belt of vegetation from the forest to the meadow (steppe), AI ranges from 0.34 to 0.58, approximately. The spatial distribution of potential forest area and meadow area was presumed by using AI and WI through the relationship between climate and vegetation in the Shaanxii area from this result.
