The hexi corridor is the northmost foreland basin of the Tibetan Plateau and its formation is controlled by the northern marginal fault of Tibet, Altyn Tagh Fault （ATF）-North Qilian Shan marginal Fault （NQF）, and the southern Kuantan Shan-Longshou Shan Fault （KLF）. So its study is important to understanding the mechanism of Tibet formation and its influence on global climate change. The oldest Cenozoic sediments in the corridor is the Huoshaogou Formation which consists of terrigenous fine conglomerate, sandstone, sandy mudstone and mudstone, depositing in al-luvial to lacustrine and fan delta sedimentary environments. Detailed paleomagnetic measurements of this sequence at Yumen clearly reveal eleven pairs of normal and reversed polarities. Fossil mammals found around the section support that most of the observed polarities can be well correlated with chrons between 13n and 18r of the standard geomag-netic polarity time scale, yielding ages of 40.2-33.35 Ma. The mean declinations of this sequence and its immediately above stratigraphy indicate an 18.3° rapid clockwise rotation of the hexi corridor. Since this sequence has been strongly folded and is capped by an angular unconformity, we think that the presence of the thick alluvial fan conglomeration at the bottom of the foreland basin may indicate the initial de-formation and uplift of the northern Qilian Shan. This proc-ess could occur at latest at 40.2 Ma, driven by the faults NQF and KLF that thrust onto the hexi corridor respectively from its southern and northern margins. These faults are in an early response to the collision of India with Asia, while the unconformable termination and rotation of the Huoshaogou Formation at33.35 Ma indicate other early episode of rapid tectonic deformation and uplift of the northern Tibet.

Sporopollen record in the Laojunmiao Section at Yumen in the hexi corridor foreland depression at the northern margin of the Tibetan Plateau revealed that during the period of 13.0―11.15 Ma the ecological environment of the Jiuxi Basin is characterized by steppe vegetation and a semi-moist climate. During 11.16―8.60 Ma prevailed forests of cypress and a still warmer, moister climate; steppe vegetation and dry climate began probably at about 8.6 Ma. Although aridification had been relaxed time and again during 8.40―6.93 Ma (forest-steppe, warm-semi-moist), 6.64―5.67 Ma (open-forest and steppe, warmer-semi-moist) and 5.42―4.96 Ma (steppe, semi-arid), the climate in the region became drier and drier in response to the fre- quent occurrence of aridity during 6.93―6.64 Ma (steppe, semi-arid), 5.67―5.42 Ma (de- sert-steppe, arid), 3.66―3.30 Ma (desert-steppe, arid) and 2.56―2.21 Ma (desert, arid). Perhaps the important findings of our study are the notable expansion of drought-enduring plants during 3.66―3.30 Ma and about 2.56 Ma and the replacement of vegetation by vast arid desert.

Photovoltaic （PV） power generation is an emerging energy industry that is developing rapidly. A number of PV power plants have been established in the desert and Gobi areas in northwest China in recent years. Is there any ecological significance to the establishment of PV power plants？ If yes, what is it？ This paper tries to find the answer by analyzing meteorological data from the hexi corridor as well as the observational data of light and vegetation in the Minqin desert area. The results show that the solar energy converted from 1 m2 of PV panels is equivalent to the solar energy that is utilized by 260.75 m2 of desert plants in the desert area. In China, there is vast area of desert and Gobi, with frequent dust storms and aeolian sand, as well as rich sunlight resources. Therefore, to develop the PV industry in the desert and Gobi regions will not only create considerable economic benefits, but will also be of great ecological significance. On the one hand, PV can effectively regulate thermodynamic equilibrium on the surface, helping to prevent sandstorms and reduce aeolian sand. The development of the PV industry is a win-win that generates economic returns and provides ecological protection by combating desertification. On the other hand, the PV industry can be developed without taking up arable land or other types of land. There are frequently high winds in the desert and Gobi region. PV power plants, together with wind power generation, are useful to transform and consume the power source that creates duststorms and aeolian sandflow in the desert and Gobi areas. This results in fewer sandstorms and reduced aeolian sandflow.

Sustainable development has become a primary objective for many countries and regions throughout the world now. The ecological footprint (EF) is a kind of concise method of quantifiably measuring the natural capital consumption and it can reflect the goal of sustainability. In this paper, the concept, the theory and method of ecological footprint are introduced. On this basis, the study brings forward the method of ecological footprint and capacity prediction. The method is employed for the ecological footprint prediction combining consumption model with population model and the technique is adopted for the ecological capacity (EC) prediction uniting the Geographical Cellular Automata (Geo CA) and Geographic Information System (GIS). The above models and methods are employed to calculate EF and EC in 1995 and 2000 and predict them in 2005 in hexi corridor. The result shows that EF is continually increasing, and EC ascended in the anterior 5 years and will descend in the posterior 5 years. This suit of method is of the character of accuracy and speediness.

基于西北干旱区河西走廊7个城市市区的水资源供应状况及其短缺程度和城市化进程加快与水资源短缺二者的矛盾关系，分析了在水资源约束下河西走廊城市竞争力和城市扩张的变动幅度等问题。认为河西走廊绝大多数城市“缺水又费水”，城市发展具有明显的“旱生性”。在水资源约束下，城市扩张的总体特征表现为以总量扩张为主，“农转非”空间和用地拓展空间大，以高耗低效扩张为主，水土资源投入产出效益普遍低下，城市发展处在主靠资源开发拉动经济增长的低级阶段，扩张质量有待提高。为了确保城市的有序竞争与扩张，建议在城市建设过程中坚持以人为本，以水为生命线，以经济发展为动力，以城市规划为法定依据，先发展后扩张，量水依法优质扩张，突出城市建设特色与个性，确保城市可持续发展。

全面抗战爆发后，中国东部大片领土被日军占领，西北成为国民政府抗战建国之重要基地。1941年，国民政府开始着力经略河西走廊，派蒙藏委员会委员长吴忠信前往甘青宁三省，游说马步芳、马步青兄弟换防。1942年，中央军入驻河西走廊，蒋介石巡视西北一个月，密切中央与西北各地的联系。国民政府加强在河西走廊的军政控制，对于解决新疆问题、维护西北稳定，具有重要意义。“嘉峪关为中华东西干线之中心”的提出，一改国人视嘉峪关外为偏远之地的既有看法，显示了抗战时期国民政府对西北边疆的重视和维护国家领土完整之决心。

河西走廊不仅是丝绸之路上沟通中原与西域的东西交通的孔道，也是联结祁连山与北方游牧地带的南北交通要道。同时作为“蒙新地区”这一相对独立的自然地理中的组成部分，它还是中原农耕文化与北方游牧文化的交错地带，具有地理交通与文化交流碰撞的双重意义，在陆路丝绸之路上的位置十分重要。地处河西走廊东边的凉州，在隋及唐前期，既要防遏北边突厥、又要防遏南边经由祁连山而至的吐谷浑等部，同时还是进一步控制河西走廊的基地和重镇，这充分体现了它的重要地位和作用。
