The major findings of this research can be summarized as follow:1 The comparison of USPED model-estimated amounts of soil erosion based on four different scales of DEMs (1:250,000, 1:50,000, 1:10,000, and 1:5,000) indicates that 1:50,000 -scale DEM is almost as good as higher-resolution DEM data in providing needed topographic information for assessing soil erosion, whereas 1:250,000-scale DEM underestimates soil erosion mainly because rill erosion and sheet erosion are greatly underestimated.2 Since precipitation is the most important forcing factor for soil erosion, the accuracy of soil-erosion estimates understandably relies on the adequacy of spatially distributing point-observed precipitation data.

取得的主要成果如下:(1)基于四个尺度(1∶250,000,1∶50,000,1∶10,000,and 1∶5,000)的数字高程模型和USPED模型计算的土壤侵蚀结果对比表明,1∶50,000的数字高程模型与更高分辨率数字高程模型提供了几乎一样的用以估算土壤侵蚀所需的地形信息,而1∶250,000的数字高程模型,由于过低的估算了细沟侵蚀和片蚀,从而过低的估算了土壤侵蚀的总量。

The regulation of gene expression is to have relations to the assembly of the DNA binding proteins which bind to DNA to initiate the transcription. Some of these proteins have the ability to promote bending or looping of DNA. The FIS protein regulates gene expression in Escherichia coli by this property of bending DNA. There are many researches to discover the mechanism of FIS protein binds to DNA. However the experiment data only show the supposititious results and figure out the model of FIS-DNA complex structure. This research uses molecular dynamics simulation to compute the detail of the interaction between FIS and DNA. We observed FIS prominently affects the DNA bending by the type of local bending. Analyzing the DNA structure properties, roll and slide, also demonstrates the local bending type and region. The hydrogen bonds between FIS and DNA are analyzed to compare with the experiment data. Finally we compute the binding free energy between FIS and DNA to estimate the result of simulation and compare with the value of λ-repressor-DNA complex.

基因的表现与结合於DNA促使DNA转录作用起始的DNA结合蛋白组装有关,一些这类的蛋白质具有促使DNA扭曲或将DNA形成环状的能力,FIS蛋白质即是藉由扭曲DNA的特性调控大肠杆菌基因的表现,目前已有很多的研究发现FIS与DNA结合的机转,然而这些实验的数据仅能显示推测性的结果,进而利用这些结果推论出FIS与DNA聚合体结构的模型,本研究利用分子动态模拟的方式计算FIS与DNA交互作用的细节,我们观察到FIS主要影响DNA的扭曲方式为DNA区域扭曲的类型,并且分析DNA结构特性roll与slide也指出扭曲方式为区域扭曲与其扭曲的区域,我们也分析FIS与DNA之间的氢键,并且与实验的资料作比较,最后我们计算FIS与DNA之间的结合自由能评估模拟的结果,并且计算出的值和λ-repressor与DNA聚合体结构的实验值作比较。

Several main results on the evolutions of the life and environment on early earth are summarized as follows:(1) the oxygenation of surface environment didn''t cease until a stable stage for 0.4Ga appeared after 1.6Ga;(2) compared to the isotopic compositions of kerogens and coexisted carbonates, the differences between two can effectively carrier the signals from local environments and bio-assemblages;(3) multiple isotopic relationships between kerogens and individual alkanes in Proterozoic samples were observed, which would depend on the specific biogeochemical processes;(4) repeated biogeochemical changes were observed accompanying Neoproerozoic glaciations, which suggesting that environmental rather than evolutionary forces were driving the biogeochemical changes;(5) the bio-radiations after Neoproterozoic glaciations were definitely suggested by molecular and isotopic data to be at the early Cambrian and after the middle of Doushantuo deposition with different triggers for them.
