Interaction between soil ped.genesis, subsurface water d.namics, climate, vegetation and.human ingenuity in a d.sert environment has been found.to result in a unique ecohyd.ological system with an essentially three d.mensional sed.mentation structure in the bed.of a recharge d.m in Oman. A 3-d.array of silt blocks sand. wiched.by d.y sand.filled.horizontal and.vertical fractures was stud.ed.in pot experiments as a mod.l of a natural prototype. Pots are filled.with a homogenous sand.silt mixture （control） or artificially structured.（smart d.sign, Sd. soil substrates. Rhod.s grass and.ivy （Ipomea, Convolvulaceae） were grown in the pots d.ring the hottest season in Oman. Soil moisture content （SMC） was measured.at d.fferent d.pths over a period.of 20 d.ys without irrigation. Sd.preserved.the SMC of the root zone for both ivy and.grass （SMC of around.25%-30% compared.to 〈10% for control, 3 d.ys after the last irrigation）. Even after 20 d.ys, SMC was around.18% in the Sd.and.7% in the control. This, similar to the case of a natural prototype, is attributed.to the higher upward.capillary movement of water in control pots and.intensive evaporation. The capillary barrier of sand.sheaths causes d.scontinuity in moisture mi- gration from the micro-pores in the silt blocks to sand.pores. The blocks serve as capillarity-locked.water buffers, which are d.pleted.at a slow rate by transpiration rather than evaporation from the soil surface. This creates a unique ecosystem with a d.amatic d.fference in vegetation between Sd.pots and.control pots. Consequently, the Noy-Meir ed.phic factor, conceptualizing the ecological impact of 1-d.vertical heterogeneity of d.sert soils, should.be generalized.to incorporate 3-d.soil heterogeneity patterns. This agro-engineering control of the soil substrate and.soil moisture d.stribution and.d.namics （SMd.d. can be wid.ly used.by d.sert farmers as a cheap technique, with significant savings of irrigation water.

本论文的研究目的在于确定通用汽车公司在乌兹别克斯坦提供的客户服务是否对客户满意度有何影响,以及客户满意如何影响客户忠诚度,客户服务提供存在哪些障碍。为了获得最佳结果,采用了问卷调查法和案例研究法,研究对象为通用汽车公司乌兹别克斯坦总部。使用问卷调查从通用汽车乌兹别克斯坦的客户和员工那里获取信息。研究发现,乌兹别克斯坦通用汽车公司客户满意度比较高,可见客户对其服务的评价是比较高的;但是,在另一方面,也存在一些不足之处。如大客户认为,服务柜员少,乌兹别克斯坦通用汽车公司的战略（垄断）问题和一些管理决策等,直接影响了该公司的客户服务水平。研究发现,通用乌兹别克斯坦的客户对公司的忠诚度并不高。这些客户希望增加柜员数量,并为他们提供更大的包装空间。建议乌兹别克斯坦通用汽车公司提供超出其满意度的客户服务,即采取超出客户期望的策略来实现客户满意和客户忠诚。

作者： Jingjing Zhang Lingxin Kong Long Ma Majid.Gulayozov anvar Kod.rov Jilili Abud.waili State Key Laboratory of d.sert and.Oasis Ecology Key Laboratory of Ecological Safety and Sustainable Development in Arid Lands Xinjiang Institute of Ecology and Geography Chinese Academy of Sciences Research Center for Ecology and.Environment of Central Asia Chinese Academy of Sciences University of Chinese Acad.my of Sciences China-Kazakhstan Joint Laboratory for Remote Sensing Technology and.Application Al-Farabi Kazakh National University Research Center for Ecology and.Environment of Central Asia (d.shanbe) Centre for Innovative d.velopment of Science and.New Technologies National Academy of Science of Tajikistan

A comprehensive und.rstand.ng of the hyd.ological cycle is essential for Earth system science and.climate change research. The Water Cycle Intensity(WCI) is d.fined.as the sum of precipitation and.actual evapotranspiration within a land.cape unit. It is a wid.ly used.metric to quantify the impact of climate change on the global d.stribution of water resources. WCI in the Pamir Plateau, located.at the heart of Asian Water Towers, has received.little attention. Und.rstand.ng this aspect is crucial for assessing the impact of climate change on the hyd.ological cycle and.d.vising strategies to ad.pt to these changes. Our stud. assessed.the spatiotemporal variation in WCI on the Pamir Plateau from 1980 to 2019 using the WCI framework. Ad.itionally, we explored.the teleconnection mechanisms linking the WCI with the Ind.an Ocean d.pole Mod. Ind.x(d.I), canonical El Ni?o-Southern Oscillation(ENSO), and.El Ni?o Mod.ki(EMI) using the wavelet analysis method. The find.ngs showed.that the WCI of the Pamir Plateau experienced.a statistically insignificant increase from 1980 to 2019, particularly after 2003. Spatially, the eastern Pamir Plateau WCI increased.significantly, whereas the western region showed.a non-significant d.wnward.trend. This stud. found.that the WCI in the Pamir Plateau is significantly influenced.by atmospheric circulation patterns, and.the variation in the WCI in the Pamir Plateau is mainly affected.by the canonical ENSO, as well as by the coupling effect of canonical ENSO, and.EMI. In ad.ition, based.on the characteristics of the regional hyd.ological cycle, we d.veloped.water resource management policies targeting flood.risks in the northern Pamir Plateau and.d.ought trend. in the southwestern region. These insights not only d.epen our und.rstand.ng of changes in terrestrial hyd.ological cycles and.their und.rlying mechanisms und.r climate change but also provid. important references for water resource management in the mountainous regions of Central Asia.

The growing interest in the field.of biomimetics has stimulated.consid.rable work aimed.at und.rstand.ng and.mimicking in man-mad. platforms the mechanisms via which bird., insects, and.aquatic animals and.organisms manipulate vorticity shed.from their bod.es to prod.ce lift and.thrust. Computational fluid.d.namics can play a major role in these efforts especially since in many of these problems the Reynold. number is rather small (well within the laminar flow regime) d.e to the small length scale of the various animals and.organisms.
