| 1 | Evapotranspiration and soil water relationships in a range of disturbed and undisturbed ecosystems in the semi-arid Inner Mongolia,China显示文摘Aims Evapotranspiration(ET)is a key component of water balance and is closely linked to ecosystem productivity.In arid regions,large proportion of precipitation(PPT)is returned to the atmosphere through ET,with only a small amount available to plants.Our objective was to examine the variability in ET–soil water relationship based on a set of ecosystems that are representative for semi-arid Inner Mongolia and its main land use practices.Methods This study used Eddy covariance(EC)data of water vapor(i.e.ET,mm),PPT(mm),soil volumetric water content(VWC,%),root biomass density and soil properties from three paired sites in semi-arid Inner Mongolia:cropland(Cropland-D)versus undisturbed grassland(Steppe-D),grazed grassland(Grazed Steppe-X)versus fenced grassland(Fenced Steppe-X)and poplar plantation(Poplar-K)versus undisturbed shrubland(Shrubland-K).The paired sites experienced similar climate conditions and were equipped with the same monitoring systems.Important Findings The ET/PPT ratio was significantly lower at Cropland-D and Grazed Steppe-X in comparison to the undisturbed grasslands,Steppe-D and Fenced Steppe-X.These differences are in part explained by the lower VWC in the upper soil layers associated with compaction of surface soil in heavily grazed and fallow fields.In contrast,the ET/PPT ratio was much higher at the poplar plantation compared to the undisturbed shrubland because poplar roots tap groundwater.The VWC of different soil layers responded differently to rainfall events across the six study sites.Except for Poplar-K,ETwas significantly constrained by VWC at the other five sites,although the correlation coefficients varied among soil layers.The relative contribution of soil water to ET correlated with the density of root biomass in the soil(R2=0.67,P<0.01).The soil water storage in the upper 50 cm of soil contributed 59,43,64 and 23%of total water loss as ET at Steppe-D,Cropland-D,Shrubland-K and Poplar-K,respectively.Our across-site analysis indicates that the site level of soil water for ET differs between land use and land cover type due to altered root distribution and/or soil physical properties.As a result,we recommend that ecosystem models designed to predict the response of a wide variety of vegetation to climatic variation in arid regions include more detail in defining soil layers and interactions between evaporation,infiltration and root distribution patterns. | Nan Lu Shiping Chen Burkhard Wilske Ge Sun Jiquan Chen | 2011 | Journal of Plant Ecology2011，4，1： | 2 |
| 2 | 夜间低温对生长在两种光强下两个芒果品种的气体交换和叶绿素荧光的影响(英文)显示文摘研究了夜间低温对两个芒果(Mangifera indica)品种翡翠芒(Khieo Sawoei)和四季芒(Choke Anand)光合生理的影响。两个芒果品种的幼苗盆栽于全光和50%相对光强下一年。在第二年的冬季,连续7天晚上将芒果幼苗移到4℃的冷库中,白天保持原条件。于低温处理前、处理期间和结束低温处理后10天中测定芒果幼苗的光合生理特征。结果表明,夜间低温导致两个芒果品种的净光合速率、气孔导度和光系统II的最大光化学效率(Fv/Fm)降低、非光化学猝灭(NPQ)上升。夜间低温对生长在全光下的芒果幼苗光合作用的抑制比50%光下的更重。翡翠芒的Fv/Fm比四季芒下降的更多,但后者的NPQ上升更多。夜间低温还导致两种光下芒果幼苗叶片的叶绿素含量下降,类胡萝卜素/叶绿素比值、丙二醛含量、膜的透性和可溶性化合物(可溶性总糖和脯氨酸)上升。解除低温胁迫后,四季芒Fv/Fm的恢复比翡翠芒的快。解除低温胁迫7天后二者的Fv/Fm能完全恢复。上述结果表明,翡翠芒对低温更敏感,遮荫可以明显缓解两个芒果品种低温引起的光抑制。 | Nabil I.ELSHEERY Burkhard WILSKE 曹坤芳 | 2008 | 云南植物研究2008，30，4： | 2 |
