Abstract从2005年到2007年,本研究根据地上植被残留量及参照前人对该地区放牧强度和演替阶段的划分,选取四个处理,分别为禁牧(G0)、轻牧(G1)、中牧(G2)和重牧(G3),对不同放牧强度下植被和土壤动态进行了三年系统监测和分析,可以说是对高寒地区放牧研究的重要补充,并且为青藏高原和的可持续利用和发展提供了较为全面的理论基础。
Other AbstractAccording the residual biomass and earlier studies, our research chose no grazing (G0), light grazing (G1), moderate grazing (G2) and heavy grazing (G3), aimed to investigate the vegetation and soil dymatics under different grazing intensity from 2005 to 2007, which not only complements previous studies on the effects of grazing in alpine area, but can also provide a theoretical framework for the utilization and development of Qinghai-Tibetan plateau.
