拉萨河流域是西藏农业资源最集中、环境承载压力最大的地区。区域土壤微生物群落结构和数量变化能够反映气候变化和人类活动影响下的土壤生态及环境脆弱特征。本研究利用高通量测序方法,对拉萨河流域天然灌木林、稀疏灌木林、人工灌木林、人工乔木林、天然草地等5种生态系统的土壤微生物群落结构及其环境影响因子进行了分析。结果表明:(1)人工灌木林土壤细菌多样性和真菌多样性均最高。(2)5种生态系统土壤细菌均以变形菌门、放线菌门和酸杆菌门为优势菌群,真菌以子囊菌门、担子菌门、壶菌门及虫霉门为优势菌。(3)在浅层土壤中,天然草地和人工乔木林的细菌群落聚类相似,在深层土壤中,天然灌木林、稀疏灌木林、人工灌木林的细菌群落聚类相似。除天然灌木林外,其余4种生态系统的真菌群落在浅层和深层土壤中均呈现分离趋势。(4)土壤含水率、电导率和速效钾对细菌群落结构影响显著,而真菌群落结构主要受土壤含水率、总氮、有效磷和速效钾含量影响。以上研究结果揭示了拉萨河流域不同生态系统土壤微生物群落结构特征。

A key requirement for well performing devices based onorganic semiconductors is to ensure ohmic contacts, where anefficient hole and electron injection and extraction can beachieved at the electrode/semiconductor interfaces. The usualway to obtain ohmic contacts involves fine tuning of the energet-ics at the interfaces by using dopants (p- type and n-type) to con-trol the Fermi level of the semiconductor [1,2], or using suitablemetals or metal oxides as electrodes [3].

Quantitative description of the high-capacity channels in unconsolidated sandstone reservoirs, into which water was injected to improve oil recovery, is a hot topic in the field of reservoir development. This paper presents a novel approach to describing quantitatively the characteristics of connected macropores in unconsolidated sandstone reservoirs using in situ production data. Based on physical simulation for formation mechanisms of high capacity channels and interwell tracer test data, a mathematical model was established to describe high-capacity channels by grey correlation theory, flow mechanism of fluid in porous media and reservoir engineering, and a program was developed to describe quantitatively the channel characteristics. The predicted results were consistent with field monitoring data （80%）, so this model could be economically and effectively used to identify high-capacity channels.

曹魏时期,相和歌艺术生产出现了新变化,表现出新的特点,主要是:设立了专业艺术生产机构清商署;"魏三祖"等最高统治者积极参与相和歌艺术生产实践;朝廷乐奏辞除汉古辞遗存外,其他皆为"三祖"依相和旧题所作新辞,且为三祖所专制;而曹魏相和歌辞的演唱功能也发生了变化,突显了对制词者个体情志的表现性一面,因而也更加侧重文辞及其意义。这些变化对于深入理解此后文人乐府歌诗的发展演变具有重要意义。
