| 1 | Quantitative estimation of the shrub canopy LAI from atmosphere-corrected HJ-1 CCD data in Mu Us Sandland显示文摘The leaf area index(LAI) is an important ecological parameter that characterizes the interface between vegetation canopy and the atmosphere.In addition,it is used by most process-oriented ecosystem models.This paper investigates the potential of HJ-1 CCD data combined with linear spectral unmixing and an inverted geometric-optical model for the retrieval of the shrub LAI in Wushen Banner of Inner Mongolia in the Mu Us Sandland.MODTRAN(Moderate Resolution Atmospheric Radiance and Transmittance Model) was used for atmospheric correction.Shrubland was extracted using the threshold of the normalized difference vegetation index,with which water bodies and farmland were separated,in combination with a vegetation map of the People's Republic of China(1:1000000).Using the geometric-optical model,we derive the per-pixel reflectance as a simple linear combination of two components,namely sunlit background and other.The fraction of sunlit background is related to the shrub LAI.With the support of HJ-1 CCD data,we employ linear spectral unmixing to obtain the fraction of sunlit background in an atmospherically corrected HJ image.In addition,we use the measured shrub canopy structural parameters for shrub communities to invert the geometric-optical model and retrieve the pixel-based shrub LAI.In total,18 sample plots collected in Wushen Banner of Inner Mongolia are used for validation.The results of the shrub LAI show good agreement with R2 of 0.817 and a root-mean-squared error of 0.173. | CHEN Wei1,2,CAO ChunXiang1,HE QiSheng1,2,GUO HuaDong3,ZHANG Hao1,2,LI RenQiang4,ZHENG Sheng1,2,XU Min1,2,GAO MengXu1,2,ZHAO Jian1,2,LI Sha1,NI XiLiang1,2,JIA HuiCong1,JI Wei1,TIAN Rong1,2,LIU Cheng1,2,ZHAO YuXing5 & LI JingLu6 1 State Key Laboratory of Remote Sensing Science,Jointly Sponsored by the Institute of Remote Sensing Applications of Chinese Academy of Sciences and Beijing Normal University,Beijing 100101,China 2 Graduate University of Chinese Academy of Sciences,Beijing 100049,China 3 Center for Earth Observation and Digital Earth,Chinese Academy of Sciences,Beijing 100190,China 4 China Key Laboratory of Ecological Network Observation and Modeling,Institute of Geographical Sciences and Natural Resources Research,Chinese Academy of Sciences,Beijing 100101,China 5 Ordos Forestry Sand Control Science Institute,Dongsheng 017000,China 6 Inner Mongolia Biomass Thermoelectricity Limited Company,Wushen 017300,China | 2010 | Science China Earth Sciences2010，53，S1： | 6 |
| 2 | Dissecting Maize Productivity:Ideotypes Associated with Grain Yield under Drought Stress and Well-watered Conditions显示文摘To increase maize (Zea mays L.) yields in drought-prone environments and offset predicted maize yield losses under future climates,the development of improved breeding pipelines using a multi-disciplinary approach is essential.Elucidating key growth processes will provide opportunities to improve drought breeding progress through the identification of key phenotypic traits,ideotypes,and donors.In this study,we tested a large set of tropical and subtropical maize inbreds and single cross hybrids under reproductive stage drought stress and well-watered conditions.Patterns of biomass production,senescence,and plant water status were measured throughout the crop cycle.Under drought stress,early biomass production prior to anthesis was important for inbred yield,while delayed senescence was important for hybrid yield.Under well-watered conditions,the ability to maintain a high biomass throughout the growing cycle was crucial for inbred yield,while a stay-green pattern was important for hybrid yield.While new quantitative phenotyping tools such as spectral reflectance (Normalized Difference Vegetation Index,NDVI) allowed for the characterization of growth and senescence patterns as well as yield,qualitative measurements of canopy senescence were also found to be associated with grain yield. | Jill E.Cairns Ciro Sanchez Mateo Vargas Raziel Ordoez Jose Luis Araus | 2012 | Journal of Integrative Plant Biology2012，54，12： | 3 |
| 3 | Ag-Zn粉末的机械合金化和随后的热处理(英文)显示文摘研究了在机械合金化过程中Ag和Zn以及随后的热处理中的显微组织演变。机械合金化在SPEX8000D铣床中进行。采用X射线衍射(XRD)﹑透射电子显微镜(TEM)和扫描电子显微镜(SEM)观察样品的显微组织。使用差示扫描量热计(DSC)研究样品的热性能。结果表明,在合金化初期的碾磨过程中能观察到ε,β,β′,α固溶体和剩余的Zn。随后,ε,β,β′和Zn相消失,α固溶体中的Zn浓度剧烈升高。在碾磨7.2ks后,机械合金化过程达到稳定状态。在此期间,α固溶体的组分和晶粒尺寸保持不变。后续热处理表明α固溶体也能够通过机械合金化结合热处理得到。最后,为了得到α固溶体,根据碾磨和热处理过程中样品的微观组织演变,提出一个最佳的工艺路线。 | Danny GUZMN Oscar RIVERA Claudio AGUILAR Stella ORDOEZ Carola MARTíNEZ Daniel SERAFINI Paula ROJAS | 2013 | Transactions of Nonferrous Metals Society of China2013，23，7： | 2 |
