Above 90% of the area of grassland is degraded and the degraded area is increasing more and more. Although the degradation is contained by the control measures to certain degree, there are still some problems such as property right restriction, difficulty in supervision, unitary policy and neglect of herdsmen's income, for this reason, the view of livestock reduction subsidy is presented. Subsidy of 50 Yuan for one sheep or goat is given to herdsman's family, 600 Yuan for one cattle; meanwhile 200kg grains is given to every one of the herdsman's family for fuel subsidy, standard culture plot construction subsidy, livestock insurance subsidy to make sure that herdsman's income is increased while the grassland is protected.

我国90%以上的草原已退化，并且还在不断扩大，虽然采取的治理措施在一定程度上遏制了草原退化，但产权制约、监理执法困难、政策手段单一以及忽视牧民增收还是目前退化草原治理过程中存在的问题，为此提出减畜补贴的观点：给予小牲畜50元／只、大牲畜600元／头的直接补贴，同时给减畜牧户家庭每人200kg基本生活口粮和燃料补贴、标准化规模养殖小区建设补贴和灾害保险补贴，做到在保护草原生态的同时促进牧民增收。

Based on the field investigation in Aug 2001 and Aug 2002, digital China Vegetation Map in 2001 and Qinghai-Xizang Plateau Vegetation Regionalization Map in 1996, vegetation characteristic along two sides of Qinghai-Xizang highway and railway is studied in this article Meanwhile, the impacts of Qinghai-Xizang highway and railway constructions on the ecosystems are analyzed using ARCVIEW、ARC/INFO and PATCH ANALYSIS It was found that:(1) Qinghai-Xizang highway and railway span 9 altitudes,12 longitudes and 6 natural regions (East Qinghai and Qilian mountain steppe region, Chaidamu mountain desert region, South Qinghai alpine meadow steppe region, Qiangtang alpine steppe region, Guoluonaqu alpine scrub meadow region and South Xizang mountain shrub steppe region);(2) the constructions of Qinghai-Xizang highway and railway destroyed natural vegetation and landscape, especially in 50m-wide buffer regions along both sides of the roads, it was estimated that the Primary Productivity deceased by about 30504.62t/a and the gross biomass deceased by 432919.25～

：根据2001-08和2002-08月野外调查数据及2001年1∶100万中国植被图、1996年1∶400万青藏高原植被区划图和2000年青藏铁路沿线自然保护区分布及功能区界调整图，以青藏公路铁路沿线植被生态系统为研究对象，运用ARCVIEW和ARC/INFO软件研究青藏公路铁路建设对沿线生态系统结构的影响，结论如下：①青藏公路铁路南北跨越9个纬度，东西跨越12个经度，共穿越青东祁连山地草原地带、柴达木山地荒漠地带、青南高寒草甸草原地带、羌塘高寒草原地带、果洛那曲高寒灌丛草甸地带和藏南山地灌丛草原地带6个自然区，对植被类型的统计结果显示了地带性。②青藏公路铁路的建设对生态系统产生直接的切割，使景观更加破碎。
