| Outline of Final Research Achievements |
The Horqin area in the Inner Mongolia of China is a climate where the grasslands are originally distributed, but the grassland has been destroyed by excessive human activities of recent centuries and transformed into desert. The desertification gave catastrophic blow to pastoral livestock industry, causing severe environmental problems such as sandstorm and yellow sand generation. Restoration of these sandy areas can be said to be the last fort to stop desertification. In this study, we first examined the relation between shrubs growing in desert area and soil micro environmental factors. As a result, it was revealed that compared to lowland, the slope and top of desert dunes had lower nutrient and moisture contents in soil and more shrubs. In addition, we succeeded in cultivating the local varieties (Aohan) of shrub Alfalfa in sandy soil. It was shown that cultivation of autogenous shrub plants had a great effect on restoration of desert.
