ON THE LAYER-ZONE OF ALPINE MEANOW ON THE QINGHAI-TIBETAN PLATEAU

In this paper, the relationship of spatial variation betwere horizontal zoneand altitudinal beits of alpine meadow on the Qinghai (Tibetan) Plateau was studiedbased on its lower and upper limit distributions. The intersectin curve bforeen thetrend-suffoces of upper and lower lindt distributions of alpine meadow shows theboundary where alhtudinally distributed alpine meadow Starts disappearing towardsthe notheest of the plateau. Ihside the interswi curve between the trend-surfaceof lower limit distnbution of alpine meadow and that of the plateau's base suffoceindicates the ropon where alpine meadow horizontally occurs.
