摘　　要：为了解释青海湖北岸草地中矿物元素分布格局及蓄积分异性的成因,通过青海湖北岸退化与封育草地中矿物元素分析比较,发现生物矿物元素饥饿效应现象,提出生物矿物元素饥饿效应假说理论,阐释了草地矿物元素空间分布格局以及具有蓄积分异性等科学问题,为退化草地恢复与重建,草地畜牧业可持续发展和草地生态系统保护等提供科学依据和管理对策。The aims of this study were to get to know the origin of the distribution pattern and accumulating differentiation behavior of mineral elements in grassland plants on the north bank of Qinghai Lake. Through comparative analysis of mineral elements of the grassland, we finally find the＂ Starvation Effect＂ phenomena of the mineral elements in biology, and put forward the＂ Starvation Effect＂hypothesis theory of the mineral elements in biology. It has answered the question why mineral elements accumulate differently in plants and can be applied to the spatial distribution patterns of mineral elements in plants. This is play an important role of the protection in grassland ecosystem, and the sustainable development of prataculture and grassland animal husbandry, and the recovery and rebuild of the degraded grassland.
