| Research Abstract |
In semi-arid region, Northeast Asia, the livestock population has rapidly increased in recent years. Excessive grazing due to large numbers of livestock causes severe degradation of natural grassland. Furthermore, the vegetation cover of grassland has been reduced by extensive droughts caused by recent climatic changes in continental East Asia. These changes are likely to result in severe soil degradation and the release of large quantities of soil dust into the atmosphere.This study clarified that estrogen-like substances were contained in Hustai National Park(HNP)-tur river water and surrounding soil. It can be considerable that estrogen-like substances from urban area cause contaminations suburb area.For human health, wildlife (Takhi), and the environmental resource protection (grassland), it is necessary to rethink conventional wisdom about effluent treatment.In so far as Takhi protection in HNP, we should keep them away from Tur river.
