项目摘要

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.

将内蒙古划分为6个区，草地划分为5个类型。本文测定了近20年来草地面积和牧草生产力的变化。草甸草原、典型草原和草原荒漠草地面积明显减少，草地生产力下降。生产力下降速率以3区、4区、典型草原区和草原荒漠区较高。而在20年中，仅草甸草原和典型草原的牲畜数量有显著增加。结果表明，不同草地类型和地带的牧草生产力存在差异，土壤全氮、全磷含量的变化可能与草地类型和地带的生产力差异有关。在本研究的20年中，各草地类型的生产力下降率与牲畜增加率之间没有相关性。气温变化和降雨量的相互作用被认为是草地退化的替代因素，但由于每个地区没有气象站，这一问题需要详细研究。
