| Research Abstract |
Inner Mongolia was classified in to 6 zones and grasslands were classified in 5 types. The changes of grassland areas and grass productivities during past 20 years were determined in the present research. The grassland areas remarkably decreased in Meadow steppe, Typical steppe and Steppe desert, and the productivity decreased in all grassland. The decrease rates of the productivities were higher in zone 3 and 4, and in Typical steppe and Steppe desert. On the other hand, the remarkable increases of the livestock were recorded only in Meadow steppe and Typical steppe during 20 years. It was demonstrated that the different grassland types and zones have different grass productivities and the possibility that total nitrogen and phosphorus concentrations in soil were related to the difference of the productivity among grassland types and zones. On the other hand, no correlation was found between decrease rate of the productivity and the increase rate of livestock in each grassland type during 20 years in the present study. The interaction of the change of temperature and the rainfall was considered as alternative factor of the grassland degradation, but detail research is needed for this problem because each area did not have a weather station.
