The analysis results for community species component and plant diversity showed that exclusion did change the species component and increase plant diversity remarkably, while the indicateor life-form structure, palatability analysis indicated that community for old exclusion is becoming perennity and unpalatability, whereas community for comparative exclusion is under stable non-equilibrium condition, in the view of vegetation coverage, mean height, biomass, palatability of plant composition, community for old exclusion has lower than new, comparative exclusion which proves partly that long-term exclusion can not increase grazing values for semi-arid rangeland.

对3种封育措施群落组成和生物多样性的分析结果表明，封育改变了群落的组成成分并增加了生物多样性，同时对群落植物的生活型、饲用价值分析计算结果则显示，老封育的群落植物逐渐向多年生发展，放牧价值开始降低，而对照区则明显处于一种非平衡的稳定状态。从3种措施植被的盖度、高度、生物量和饲用价值来看，老封育区均低于新封育区和对照区，表明长期封育不利于促进并提高草场的放牧利用价值。

The crystallization temperature and pressure of clinopyroxene phenocrysts from the ankaramite and basalt were estimated on the basis of the clinopyroxene-melt equilibrium principle: 1345～1366℃ and 1.75～2.05Gpa for ankaramite, with average geothermal gradient of 20-24℃/km, suggesting anomalous heat or geothermal gradient in this region may be one of the key reasons to produce the porphyry copper deposits in the region. In contrast, those in the basalts fomed under a relatively low crystallization temperature (1129～1191℃), and the pressure (1.19～1.60Gpa) and depth (39～53km), suggesting that the basalt formed under a condition of lower temperature and pressure.

根据单斜辉石-熔体平衡原理计算了富辉橄玄岩和玄武岩中斑晶相辉石形成的温度和压力，前者变化范围主要集中在1345～1366℃和1.75～2.05GPa，其深度相当于58－67km，平均的地温梯度大约20～24℃/km，说明该区具有异常的热或地温梯度，这可能是导致本区斑岩铜矿形成的主要原因之一；后者的温度和压力都相对较低，分别为1129～1191℃和1.19～1.60Gpa，而相应的深度为39～53km，暗示着玄武岩是在相对低温低压的环境中形成的演化岩浆。
