Erosion and Sediment Production in Small Watershed in Purple Hilly Areas and Prevention Techniques

Purple Soil distributes extensively and mainly in China. Because of abundant easily weatherable parent rocks/materials and unstable soil structure, and also influenced by parent materials, usage systems, and slope gradients, erosion and sediment production of purple soils are very severe with main fashions of water erosion and gravitational erosion. Basing on observed data in small watersheds, rainfall erosivity,vegetation coverage, previous soil water content, flow and relating factors such as climate, topograph of small watershed,land usage, and soil kinds are all the influence factors of erosion and erodibility of purple soil as well as sediment production and transport in small watershed of purple hilly areas.The effective technological countermeasures of ecosystem restoration, agricultural tillage for water conservation and erosion prevention, agriculture project, and soil changing for fertility and anti-erosion were provided.

Dynamic Characteristics of Inter-Satellite Links in LEO Networks

To establish an efficient inter-satellite link (ISL) in an LEO network, the effect of geometric characteristics of ISL on the ISLs and the devices on the LEO satellite should be examined. Because of the continuous movement of the LEO satellite, the time-varying behaviours of the ISL's geometric charactersistics continuously change with the changes of the satellite's position on the orbit. These dynamic geometric characteristics of the ISLs are important for ISL's performance analyzing and the design of the devices on the LEO satellite. This paper describes dynamic geometric characteristics of ISL, analyzes the impact of these regulations on the tracking system of the satellite's antenna and the power adjusting system of the satellite's transmitter, with the Iridium system as an example.     

在UBBE框架下考虑不肯定的上界的估计方法

对目前的ＵＢＢＥ模型进行了适当的推广，使在解决估计问题时可以考虑那些可能是误差上界的数值，并在此基础上提出了一种方法，能够通过对估计精度和可靠性进行合理的权衡确定所需估计值，实际案例研究结果表明所提方法能够较好地解决估计精度和可靠性之间的矛盾。     

儒家"诚信"特色及其现代转化

儒家"诚信"作为具有中国特色的古典伦理形态,与现代"信用"有许多本质差异。要实现其现代转化,必须达到:由适用于"熟人"社会的特定伦理,转变为适用于"陌生人"社会的普遍伦理;由一般人伦伦理,引入经济伦理;由主观"自诚"模式,转变为契约"合意"模式;由从属于封建礼教的次要道德义务,转变为从属于"社会公正"的道德义务,并进而提升为反映现代人本质的基本道德义务。为达此转化,需要创设诸如完善市场机制、推行宪政民主、培养契约文明观念等社会文化条件。这将是一个艰难漫长的自然历史进程。     

福建戴云山自然保护区植被景观斑块特征分析

利用戴云山自然保护区的植被分布图和地形图等,在GIS软件支持下提取植被景观斑块信息,从植被景观组分斑块特征的角度对戴云山自然保护区的植被景观格局及破碎化进行分析.研究结果表明,在戴云山自然保护区中,温性针叶林、常绿阔叶林、暖性针叶林景观是该区的3个主要景观类型;景观组分的面积、周长、斑块数的分布不均衡;各景观组分面积与周长的分布相似,而斑块数的分布却没有明显的规律性.植被景观斑块总体特征分析表明,农地景观的破碎化程度高,而温性针叶林、常绿阔叶林与暖性针叶林景观的破碎化程度低.
