新疆地区遥感、融合和陆面模式模拟的蒸散产品的不确定性分析

蒸散是干旱区水资源消耗的主要方式,由于该地区地表植被覆盖稀疏且空间异质性较大,目前国际常用的众多蒸散产品的结果存在较大差异。故选取中分辨率成像光谱仪(MOD16)蒸散产品、全球陆地蒸散阿姆斯特丹模型(global land evapotranspiration amsterdam model,GLEAM)和通用陆面模式(common land model,Co LM)的蒸散产品为代表,利用三角帽(three cornered hat,TCH)方法定量评价3种蒸散产品在新疆干旱区模拟结果的空间不确定性。结果表明:GLEAM和MOD16蒸散产品的空间分布规律相似,山区蒸散值均显著高于平原区;Co LM在阿尔泰山、天山蒸散值显著高于平原区。此外,全疆多年平均蒸散值分别为:GLEAM[(142.36±11.11)mm·a~(-1)]、Co LM[(126.66±19.12)mm·a~(-1)]、MOD16[(78.64±4.61)mm·a~(-1)]。基于TCH方法的全疆蒸散模拟的不确定性结果大小依次为:Co LM(24.18 mm·a~(-1)),GLEAM蒸散产品(21.58 mm·a~(-1)),MOD16蒸散产品(17.66 mm·a~(-1))。在灌丛,山地半干旱区和山地半湿润区,3种蒸散产品的不确定性显著不同,其中Co LM不确定性最大(33.47 mm·a~(-1)、30.46 mm·a~(-1)、32.11 mm·a~(-1)),MOD16不确定性最小(9.50 mm·a~(-1)、14.80 mm·a~(-1)、14.34 mm·a~(-1))。量化新疆地区蒸散的不确定性为更加准确估算该地区的蒸散有着重要的科学意义。

柑橘黄龙病兼性厌氧型伴生细菌的分离及优势菌群分析

To analyze the diversity of entophytic bacteria and find the companion microbe in Huanglongbing pathogen-infected and healthy citrus plant tissues, various parts of citrus tissues were collected from different locations of citrus planting areas. The facultative anaerobic and entophytic bacteria were isolated and identified based on bacterial morphology, physiology, biochemistry characteristics and PCR-DGGE analysis (denaturing gradient gel electrophoresis, analysis of the sequence of 16S rRNA V6-V8 fragment). By the directional isola-tion of the facultative anaerobic and entophytic bacteria and 16S rDNA amplification methods, total 12 genera of bacteria were identified from 19 cultivable bacterial populations. The dominant bacterial population were Bacillus sp. (IF: 21. 03% ), Planococcus sp. (IF:20. 69% ) and Pseudomonas sp. (IF:17. 44% ) in healthy citrus tissues, while Curtobacterium sp. (IF: 29. 07% ), Bacillus sp. (IF: 23. 12% ), Microbacterium sp.(IF: 21. 09% )in infected citrus plants. Based on the results of DGGE, 9 genera of cultured bacteria were identified. The dominant bacteria population was Serratia sp. (IF: 28% ), and Pantoea sp. (IF: 14% )was second only to it. ‘Candidatus Liberibacter asiaticus爷was found only in tangerine pith of deformed orange fruit, which suggested that the contents( > 1% )of Huanglongbing were more in diseased fruits. The density and species of entophytic bacteria were also observed in remarkable difference between infected and healthy citrus plants according to the DGGE profiles.

Species composition and diversity,and carbon stock in a dune ecosystem in the Horqin Sandy Land of northern China

In this study, we determined carbon allocation and carbon stocks in the plant-soil system of different dune ecosystems in northeastern China. We quantified the species composition, above- and below-ground biomasses, and carbon stocks of three dune types(i.e. active dunes, semi-stabilized dunes and stabilized dunes) and their corresponding inter-dune lowlands(i.e. interdune lowlands of active dunes, interdune lowlands of semi-stabilized dunes and interdune lowlands of stabilized dunes) in the Horqin Sandy Land. The results showed that the succession series on interdune lowlands of the Horqin Sandy Land confirmed differences in species composition of the various dune types. Aboveground carbon(AGC) on the interdune lowlands of semi-stabilized dunes(33.04 g C/m2) was greater(P<0.05) than that on the interdune lowlands of active dunes(10.73 g C/m2). At the same time, the different dune types did not show any significant differences(P>0.05) in belowground plant carbon(BGC). However, the percentage of plant BGC in interdune lowlands of active dunes(81.5%) was significantly higher(P<0.05) than that in the interdune lowlands of semi-stabilized dunes(58.9%). The predominant carbon pool in the study dune ecosystem was in the soil. It accounted for 95% to 99% of total carbon storage. Soil organic carbon(SOC) was at least 55% greater(P<0.05) in the interdunes than in the dunes. Stabilized dunes showed at least a 37% greater(P<0.05) SOC content than active dunes up to a 1-m soil depth. Meanwhile, SOC content of interdune lowlands of semi-stabilized dunes was greater(P<0.05) than that of interdune lowlands of active dunes only up to a 20-cm soil depth. The dune ecosystem showed a great potential to store carbon when interdune lowlands of active dunes were conversed to interdune lowlands of semi-stabilized dunes, which stored up to twice as much carbon per unit volume as interdune lowlands of active dunes.

大麦条纹花叶病毒中国株三基因盒(TGB)序列对比分析

 The tripe gene block (TGB)genes of Barley stripe mosaic virus China strain (BSMV-CH)were amplified from cDNA of BSMV-CH RNAβ (GenBank accession No:AY789694)by PCR with special primer pairs, and cloned into pMD18-T vector for sequencing. Analysis of the sequences showed that the full length of BSMV-CH TGB1, TGB2 and TGB3 were 1 539, 396 and 468 bp, with deduced 512, 131 and 155 amino acids, respectively. BSMV-CH TGB1 shared 94.1%-95.4% nucleotide identities and 91.0%-94.5% amino acid identities with that of other BSMV strains, BSMV-CH TGB2 shared 96.5%-97.2% nucleotide identities and 98.5%-99.2% amino acid identities with that of other BSMV strains, and BSMV-CH TGB3 shared 95.7%-96.6% nucleotide identities and 94.2%-96.8% amino acid identities with that of other BSMV strains. Phylogenetic tree based on the amino acid of Hordeiviruses TGB genes showed that BSMV-CH was relatively closed to CV17 in genetic relationship. Therefore, BSMV-CH was deduced to be a recombined strain of CV17 and CV42.

Adjustment of precipitation measurements using Total Rain weighing Sensor(TRwS)gauges in the cryospheric hydrometeorology observation(CHOICE)system of the Qilian Mountains,Northwest China

Precipitation is one of the most important indicators of climate data,but there are many errors in precipitation measurements due to the influence of climatic conditions,especially those of solid precipitation in alpine mountains and at high latitude areas.The measured amount of precipitation in those areas is frequently less than the actual amount of precipitation.To understand the impact of climatic conditions on precipitation measurements in the mountainous areas of Northwest China and the applicability of different gauges in alpine mountains,we established a cryospheric hydrometeorology observation(CHOICE)system in 2008 in the Qilian Mountains,which consists of six automated observation stations located between 2960 and 4800 m a.s.l.Total Rain weighing Sensor(TRwS)gauges tested in the World Meteorological Organization-Solid Precipitation Intercomparison Experiment(WMO-SPICE)were used at observation stations with the CHOICE system.To study the influence of climatic conditions on different types of precipitation measured by the TRwS gauges,we conducted an intercomparison experiment of precipitation at Hulu-1 station that was one of the stations in the CHOICE system.Moreover,we tested the application of transfer functions recommended by the WMO-SPICE at this station using the measurement data from a TRwS gauge from August 2016 to December 2020 and computed new coefficients for the same transfer functions that were more appropriate for the dataset from Hulu-1 station.The new coefficients were used to correct the precipitation measurements of other stations in the CHOICE system.Results showed that the new parameters fitted to the local dataset had better correction results than the original parameters.The environmental conditions of Hulu-1 station were very different from those of observation stations that provided datasets to create the transfer functions.Thus,root-mean-square error(RMSE)of solid and mixed precipitation corrected by the original parameters increased significantly by the averages of 0.135(353%)and 0.072 mm(111%),respectively.RMSE values of liquid,solid and mixed precipitation measurements corrected by the new parameters decreased by 6%,20% and 13%,respectively.In addition,the new parameters were suitable for correcting precipitation at other five stations in the CHOICE system.The relative precipitation(RP)increment of different types of precipitation increased with rising altitude.The average RP increment value of snowfall at six stations was the highest,reaching 7%,while that of rainfall was the lowest,covering 3%.Our results confirmed that the new parameters could be used to correct precipitation measurements of the CHOICE system.

Spatial pattern of land cover change in China’s semiarid environment

This study seeks a routine to quantify spatial pattern of land cover changes in semiarid environment of China based on post-classification comparison method. The method consists of three major steps: (1) the image classification and unification of classified results based on two-level land cover classification themes, (2) the establishment of land cover change classes based on an unification land cover classification theme, (3) the reclassification and mapping of land cover change classes with three overall classes including no-change, gain and loss based on the unification land cover class. This method was applied to detect the spatial pattern of land cover changes in Yinchuan Plain, one of famous irrigation agricultural zones of the Yellow River, China. The results showed the land cover had undergone a remarkable change from 1991 to 2002 in the study area (the changed area was over 30%). Rapid increase of cropland (12.5%), built-up area (131.4%) and rapid decrease of bare ground (51.7%) were alarming. The spatial pattern of land cover changes showed clear regional difference in the study area and was clearly related to human activities or natural factors. Thus, it obtained a better understanding of the human impact on the fragile ecosystem of China’s semiarid environment.     

来源于新疆的3 个苹果褪绿叶斑病毒分离物的分子变异研究

Apple chlorotic leaf spot virus (ACLSV) isolates from Korla pear (KI-2), New pear no. 7 (XI-1) and Red Fuji apple (API-4) were collected from XinJiang and characterized by analyzing sequences of their near genomic 3忆-terminal. The RT-PCR products were cloned, and analyzed by single-strand conforma-tion polymorphism (SSCP). Eight out of 39 collected positive clones showing different SSCP patterns were sequenced. The results showed that the amplified products had sizes ranging 676 - 703 bp, including partial coat protein (CP) gene (506 bp, accounts for 87% of the complete cp gene) and 3忆-terminal non-coding re-gion (3忆NCR) sequences. The cp gene sequences from isolate KI-2 showed a high intra-isolate divergence,with 84. 8% - 85. 4% identities at the nucleotide (nt) level, and the intra-isolate identities were 99. 8 % and 92.5% - 99. 8 % for isolate XI-1 and API-4, respectively. Phylogenetic analysis on the nt sequences of cpgene showed that the analyzed ACLSV variants from three isolates fell into two different clusters. A variant KI-2-6 from KI-2 was clustered into a group with an apple isolate aclsv-c from China and a plum isolated from France, and all other variants fell into a large cluster. The 3忆NCR sequences of these variants were identical ranging 80. 6% - 100 % .

Effects of vegetation cover on recruitment of Ulmus pumila L. in Horqin Sandy Land,northeastern China

Understanding the effects of vegetation cover on seedling survival is helpful for promoting vegetation restoration in environmentally fragile zones. This study was conducted in the desertified, moving sand dunes of Horqin Sandy Land, Inner Mongolia, northeastern China. We hyphothesized that(1) seed density(i.e., number/m2) increases as vegetation cover increases, and(2) there will be more surviving seedlings in locations with higher vegetation covers. Total vegetation cover and initial densities of seeds, germinated seeds and surviving seedlings of Ulmus pumilia were evaluated under various vegetation covers in trying to clarify the effects of vegetation cover on the early stages of the plant life history. In agreement with the first hypothesis, initial seed densities were greater(P<0.05) under higher vegetation covers. The relationship between vegetation cover and initial seed density was represented by a quadratic regression, where a threshold occurred with a vegetation cover of 36%(P<0.05). The higher total vegetation covers, however, did not result in increased densities of germinated seeds(P>0.05), which on average represented 16.7% of initial seed densities. Even more, three months after the study initiation, total vegetation covers were similar(P>0.05) at all positions in the dunes, and they determined a similar number(P>0.05) of surviving seedlings at those positions(i.e. the second hypothesis had to be rejected). The mean number of seed- lings that survived at all positions was only 4.5% of germinated seeds. The number of surviving elm seedlings(0 to 1.7 seedlings/m2) under various vegetations covers(12.2% to 20.8%) at all dune positions by late summer would most likely not contribute to vegetation restoration in the study area.
