The rate of subsidence has been decreasing from area near vertex of delta to the coastal zone and some place is even rising, particularly in the early formed area. What is the different in the coastal is that the rate of subsidence is still high and can sustain a long time. This is because the land subsidence in the delta is mainly caused by the consolidation of sediments if there is no human activity. Especially in the newly formed area, Qingshuigou sub-delta, the rate of subsidence was more than 50 mm/a in the begining and now is still higher than 10 mm/a. When the newly sediments discharged by the Yellow River landed on the subaquatic delta, its load can drive the concolidation of the silt, which is on the surface of the Bohai seafloor. The rate of consolidation of the silt will be decreasing quickly in the first years, but still a long time in the later time with a slow rate.

研究结果表明：现代黄河三角洲在以宁海为顶点的河口扇形区域，近期均经历了不同程度的地表下沉过程，但是随区域地理位置和时间的不同，地表变化空间差异性比较明显；三角洲顶点附近区域的下沉速率自上世纪末开始逐渐减小，后期甚至出现轻微的抬升；滨海沿岸附近地区的地表形变特征相对比较复杂，各期叶瓣相互叠置及其各类沉积物的不均匀分配，使由沉积物自然固结压实引起的地表形变具有显著的空间差异；目前，除清水沟流路叶瓣表现为快速沉降以外，其它滨海沿岸区基本上都表现为微弱的下沉。

Modern approach methods of geography, ecology, quantitative analysis, expert integration, remote sensing image analysis and geographical information system were combined to reveal the matters in this paper. The eco-geographical background of the research area and the research work studied by other scholars were comprehensively expatiated. The temporal and spatial variation of precipitation and soil moisture, vegetation and soil distribution, and land use/land cover were compared as well. On the basis of foregoing analysis, the eco-geographical differentiation was discussed. According to principles and indicators, with extension engineering method and integrated analysis, the physical geography boundary between subhumid and semiarid areas were demarcated. By using remote sensing image analysis, wavelet analysis of the perennial precipitation and temperature, and the comparison of temporal and spatial variation of the desertification, this paper accounted for the regional response to global environmental change and suggested the dominant environmental problems.

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。

Regional Economic Policy approach in Game Theory is prevailing in regional policy studies and regional development practice. Unfortunately, the efficiency of this approach that is always involved into the relation between local government and central authority is on the shadow of suspiciousness.

区域经济政策博弈方法、模型已经广泛及使用区域经济政策的教育研究，但是博弈理论是否适用于区域经济政策中的中央与地方政府关系的实践研究，仍然值得商榷。
