昆仑岩带新生代钾质火山活动是青藏高原北缘深部动力学过程的重要记录。有关岩浆源区的性质和岩浆产生的机制一直存在较大的认识分歧。阐述了昆仑岩带黑石北湖钾质火山岩的岩石学和地球化学特征,并与西昆仑康西瓦和泉水沟新生代火山岩进行了成因对比分析。研究表明,昆仑火山岩带玄武质岩石的K2O和Na2O含量变化较大,从钠质过渡到钾质,硅碱图显示玄武质初始岩浆向钾质安粗岩方向演化。黑石北湖火山岩的高场强元素和Sr、Nd同位素组成显示岩浆源区具有EMⅡ的性质。岩石LREE的强烈富集和HREE的强烈分馏指示岩浆来自富集型含石榴子石地幔源区。不相容元素K/Nb、Ba/La等比值具有岛弧火山岩与OIB型玄武岩的过渡特征,指示源区为曾遭受软流圈流(熔)体交代的古俯冲地幔楔。

Science China Earth Sciences 2006年第S2期49卷 150-162页

Two years of eddy covariance measurements of above- and below-canopy carbon fluxes and static opaque chamber and gas chromatography technique measurements of soil respiration for three treatments (bare soil, soil+litterfall, soil+litterfall+seedling) were carried out in a tropical seasonal rain forest. In addition, data of photosynthesis of dominant tree species and seedlings, leaf area index, litter production and decomposing speed, soil moisture, soil temperature and photosynthetic photon flux density within the forest were all measured concurrently. Data from January 2003 to December 2004 are used to present annual variability of carbon flux and relationships between carbon flux and impact factors. The results show that carbon flux of this forest presented unusual tendency of annual variation; above-canopy carbon fluxes were negative in the dry season (November-April) and mainly positive in the rainy season, but overall the forest is a carbon sink. Carbon flux has obviously diurnal variation in this tropical seasonal rain forest. Above-canopy carbon fluxes were negative in the daytime and absolute values were larger in the dry season than that in the rainy season, causing the forest to act as a carbon sink; at night, carbon fluxes were mainly positive, causing the forest to act as a carbon source. Dominant tree species have greater photosynthesis capability than that of seedlings, which have a great effect on above-canopy carbon flux. There was a significant correlation between above-canopy carbon flux and rate of photosynthesis of tree species. There was also a significant correlation between above-canopy carbon flux and rate of photosynthesis of seedlings; however, the below-canopy carbon flux was only significantly correlated with rate of photosynthesis of seedlings during the hot-dry season. Soil respiration of the three treatments displayed a markedly seasonal dynamic; in addition, above-canopy carbon fluxes correlated well with soil respiration, litterfall

利用RCPs情景,对青海高原典型生态功能区2019-2050年气温和降水变化趋势进行了研究。结果表明:在RCP2.6、RCP4.5和RCP8.5三种排放情景下,三江源地区、祁连山地区、柴达木盆地地区、青海湖地区和河湟地区5个生态功能区的年平均气温均呈升高趋势;在RCP2.6和RCP4.5情景下河湟地区的年降水量呈减少趋势,其他4个地区的年降水量呈增加趋势,在RCP8.5情景下,5个生态功能区的年降水量均呈增加趋势。通过年代际分析发现,在RCP2.6、RCP4.5和RCP8.53种排放情景下2040-2049年年平均气温达到高峰,而且在RCP4.5和RCP8.5情景下2040-2049年5个生态功能区的气温达到2.0~2.1℃和2.4~2.5℃。通过M-K检验发现,在RCP2.6、RCP4.5和RCP8.5情景下5个生态功能区的年平均气温均发生了突变,但发生突变的时间不一样。柴达木盆地地区的降水在3种情景下,在不同的年份中发生了突变;青海湖地区的降水在RCP4.5和RCP8.5情景下发生了突变;祁连山地区的降水在RCP4.5情景下发生了突变;河湟地区的降水在RCP2.6情景下发生了突变,三江源地区的降水在RCP8.5情景下发生了突变。通过累积距平检验可知,在RCP2.6、RCP4.5和RCP8.53种情景下,5个生态功能区年平均气温和降水量的累积距平曲线均呈上升趋势,表明2019-2050年是气温偏暖,降水偏多的时期。1971-2000年5个生态功能区的气温和降水量均呈升高趋势,在中、高排放情景下5个生态功能区的增温速率均大于气候基准年的增温速率。除河湟地区外的4个生态功能区基准年的降水增加速率均小于未来30多年3种排放情景下的降水增加速率。在这种暖湿环境中,牧草(农作物)的生长将会受到一定的影响,从而影响畜牧业和农业的发展。
