Love was the maternal donor of the polyploid Elymus; the "Y" genome existed in the StY-genome Elymus may be differentiated from the St genome, i.e., the autopolyploid StSt-genome species probably experienced genomic differentiation within a species after autopolyploidy, leading to the significant genomic change and resulting the StY-genome allotetraploids; the StY genome species distributed in the Central Asia with a high level of genetic diversity radiated to the Western and Eastern Asia, under the environmental selection and other factors, and only a few species spread to the western Asia and most species have remained in the Central and eastern Asia.
3分子证据表明在StY基因组的物种之间有明显的地理分化,中亚可能是StY基因组披碱草属植物的分化中心,并在此基础上,StY基因组的披碱草属植物向东亚和西亚进行了快速的辐射,形成了现代StY基因组物种的分布格局;多次杂交、迁移和分化是StY基因组的披碱草属植物进化的主要动力。(4)拟鹅观草属物种可能是所有披碱草属植物的母本供体。

Taking the administrative villages as units, a comprehensive and detailed survey was made to attain the rich and reliable data, including the information about the status of the land use, the relationship of the land supply and demand, the living standards of farmers and the minimum of urban resident living guarantee and so on. Then the estimating system was established. Afterwards, basing the survey and the system, the character of each unit was transfer into data. And, utilizing the frequency law, the whole county was divided into four expropriation land blocks. The area was measured and the map, showing the differences between blocks, of the Arable Land Blocks for expropriation of Siyang was protracted by the method of GIS. Finally, the land expropriation price is calculated by agricultural land economical function compensate method and urban construction land criterion price avulse method, then the price was tested by expropriation case comparison method. It is beneficial not only for protecting farmers rights and interests, but also for link up with the current land compensate standard, so this way to calculate the land expropriate price is more reasonably.
以行政村为基本单元,对该地区的农用地利用现状、土地供求关系、农民生活水平扣城镇居民最低生活保障水平等情况进行了调查,建立征地区片价格评价体系,根据每个评价单元的综合评价分值,运用总分频率法将全县分为四个区片,并对各级区片进行面积量算,借助地理信息技术绘制了《泗阳县农用地征地区片价格分布图》,显化了农用地征地区片价格的空间分布及其差异,最后运用农用地经济功能价格补偿法和城镇建设用地基准地价剥离法综合测算农用地征地区片价格,并用征地案例比较法的测算结果加以比较验证,证明此测算结果相对更加科学合理,既有利于保障被征地农民的合法权益,又有利于与现行的征地补偿标准相衔接。

In this research a new mathematical model - cubic polynom with two given derivatives at end points - was proposed which can good match the S-shpae curve.This model has a number of analytical features:describing the geographic phinomena prosesses in three hierarchies (textural fractal,structural fractal and state fractal); the boundary values of the structural fractal can be considered as the boundary values of interval of scaleless.
在研究中提出了扩展分维表达函数:带导数三次多项式,它能很好地表达反S形分布曲线,具有一系列解析特征:可从三个层次(纹理分形、结构分形和态势分形)上描述地理现象或过程;其中结构分形的边界可近似地看作是非扩展分维无标度区的上下界。

Time series simulations are consistent with sediment records from lake bottom cores back to 100 years ago, and spatial distribution modeling of nutrient resources are agreement with changes in the geographical features. The work suggests that the simulations can catch basic characters of the basin nutrient changes, and provides a powerful tool to evaluate nutrient resources, sedimentations and distributions responding to historical changes in catchment environments.
模拟总氮和总磷浓度与太湖沉积钻孔沉积样推算的水体含量的数量级和变化范围相当,太湖流域的营养盐空间来源模拟也能够与流域自然地理变化吻合,表明模拟能够捕捉到流域营养盐历史变化特征,对湖泊营养物质来源、沉积和空间分布的流域环境历史变化响应具有良好模拟能力。

Using Spatial Lag Model and Spatial Error Model, a spatial econometric analysis on institutional spillover effect of marketization degree in China's provinces and the effect on regional economic growth is performed. The results of spatial analysis show that after nearly 30 years' development of China's provincial economies reform and opening, the spatial association becomes closer while geographical clustering obviously intensifies, and the institutional spillover effect among the provinces becomes confessedly.
摘要本文从空间分析的角度研究各地区市场化进程的空间效应及其对区域经济增长绩效的影响,空间计量经济分析的结果表明市场化进程的空间分布在整个样本区间与GDP、资本和劳动一样呈现出集聚的趋势,区域差异显著,各地区的市场化进程在地理空间上存在显著的自相关关系,证实了各地区市场化进程存在制度溢出效应。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
