On the basis of pollen analysis of surface sample in North China, polynomial function analysis method was applied to establish pollen climate response surface of Pinus, Betula, Quercus, Artemisia, Chenopodiaceae, Compositae, Picea, Ephedra, Gramineae in North China, therefore an easy and applicable method for reconstructing palaeoclimate and palaeoenvironment with data of fossil pollen was founded; Multi-analysis method was applied to analyse the principal elements of surface sample pollen in central Inner Mongolia Steppe, the assemblages of surface sample pollen in steppe area and its relationship with vegetation type were discussed with helps from spore-pollen analysis of a peat section in Chasuqi, Inner Mongolia and 〓C chronometer, fossil pollen data were obtained with high resolution on the peat section in Chasuqi. Vegetation succession and environmental changes since Holocene at resolution of 70 years were primarily reconstructed in south Mount Daqingshan and Plain Tumete. The changes in the area were copmared with those in the neighbouring areas during the same period. It was found that Holocene environmental change had undergone the following stages: cold-arid, temperate-wet, warm-wet, temperate-arid and cold-arid, and the climatical optimum period occurred in 5000-4100 aB.

Because of the regional difference of soil and climatic conditions, the division of 4 stages of soil moisture circulation is not all the same between different areas; the soil moisture dynamics between different dry farming areas in the Yellow River Basin is contrasted in this report. The results indicate that soil moisture increases gradually from dry semi-arid area to semi-arid area, dry semi-humid area and semi-humid area, and the high value district generally appears during soil moisture resuming period in rainy season or soil melting period. While the low value district appears at the stage of fast evaporation in spring or slow evaporation in autumn; in views of vertical changes of soil moisture, it is showed that the variation range of upper lays is larger than that of lower among the different dry farming areas in the Yellow River Basin.
由于各区域之间土壤、气候条件的差异,各地土壤水分循环4个阶段的划分也不尽相同;黄河流域不同旱作类型区土壤水分动态变化比较结果表明:就季节变化而言(来源:A70b0B0bC论文网www.abclunwen.com),由半干旱偏旱区→半干旱区→半湿润偏旱区→半湿润区土壤水分含量呈逐渐增加的变化趋势,而且高值区一般出现在雨季恢复阶段或春季土壤融冻返浆时期;而低值区均出现在春季大量蒸发阶段或秋季缓慢蒸发阶段;就垂直变化而言,黄河流域不同旱作类型区土壤水分垂直变化的趋势均表现为上层变化幅度较下层大。

ARID (AT-rich interaction domain) protein is a transcription factor family in higher eukaryotes that regulates cell proliferation, development, and differentiation. Specificity of DNA binding ability in this family prefers AT-rich sequences, but some ARID family proteins are not sequence-specific DNA-binding proteins or they do not bind AT-rich sequences. We found two genes that encode ARID in Giardia lamblia genome database, garid1 and garid2. We analyzed the function of garid1 first. AU1-tagged gARID1 was found to localize to nuclei. During encystation, gARID1 mRNA level decreased emphatically, but protein level increased. We also found that gARID1 can bind AT-rich initiator of the cwp1 promoter by EMSA. Mutation analysis revealed gARID1 binding sequence was AGATC and AATAAAATA. We used ChIP to demonstrate that gARID1 can bind cwp1 gene promoter in vivo.
ARID(AT-rich interaction domain)蛋白质家族是真核生物的一种转因子,在许多同种的真核生物有它的同源基因,这个家族的蛋白质通常与调控细胞的生长、发育和分化的作用有关,而这个家族的蛋白质和DNA的结合能,各种ARID蛋白质的专一性尽相同,过大致上偏好於和AT-rich的序结合;我们已经在形鞭毛虫的基因组中找到个含有ARID 的基因,分别是garid1和garid2,我们首先对於garid1做分析;将AU1标记接到gARID1转染形鞭毛虫,用免疫萤光染色可发现gARID1存在於细胞核中。gARID1的讯息RNA在囊体化后会明显下,过其阳性染色和蛋白质表现有明显增加;EMSA实验中也发现gARID1会明显的与cwp1基因启动子之AT-rich initiator结合,经由突变序分析,也显示gARID1的结合序为AGATC和AATAAAATA,随后我们也用ChIP证明gARID1在细胞内也的确会和cwp1基因的启动子结合。

Reference crop evapotranspiration (ET0) and new wetness index were both calculated and analyzed according to Penman-Monteith scheme recommended by FAO with routine meteorological data from 616 weather stations in China from 1975 to 2004. In terms of grades of wetness index from Chinese Climate Classification Criterion, China is classified into severe arid, arid, semi-arid, semi-humid and humid zones, respectively, which are compared with the demarcations from rainfall-based indices in order to reveal the similarity and difference in association with the two schemes under current global climate warming. Besides, the spatio-temporal analysis of climate wetness over the country in the past thirty years was performed.

Beijing Real Estate and Construction Bar Association Professional Committee of Liu Hua, deputy director of the Law Society: The contract agreement in the area, it seems to me there are at least two flaws: First, it agreed to construction area for the sale area, construction area is passed and the pool area and the area, and in this contract on the pool area also lacks transparency, developers will not tell you specific assessments where the location of the area, the specific area is the number, which for him provided an opportunity for fraud; Secondly, the contract agreed by the parties, permit the forecast area of 3% error, if the pool size increases as long as no more than 3%, you can only increase the pool for this increase the size back the principal.

Shule River project area is located in northwest China\'s Gansu province,Hexi Corridor,which is the largest agricultural crop production base of Gansu province and typically arid and semi-arid areas. There are characteristics such as scarce rainfall,the temporal and spatial distribution inequality,strong evaporation,fragile ecological environment,the limited quantity of surface water. Agriculture,the people\'s living and ecological environment are significantly dependent on the groundwater. Based on the collection and processing of regional hydrological and geological data and the groundwater monitoring data,using the numerical simulation,geostatistics theory and multi-objective evolutionary algorithm,this paper studied the monitoring and evaluation of groundwater resources from the three aspects: groundwater numerical simulation and prediction,groundwater spatial variability and distribution and optimization modeling and sloving of groundwater monitoring network. The main work and research lies:(1) Using Yumen-Tashi basin,Anxi-Dunhuang basin and Huahai basin as study area,this paper used modflow model to simulate groundwater flow of three areas.
