Besides, six horizon samples of 4 other profiles randomly takenfrom the studied area were examined for calculation of the redistributing enrichment coefficient, which wasapplied for a better understanding of the element redistribution between soil and clay fraction along with soildevelopment. The results showed that the enrichment, migration and redistribution of the elements variedstrongly among the investigated soils and horizons, due to the differences of weathering degrees and moisturestatus, influences of sea bird activities, etc.展开更多

It was concluded that on the weathering crusts resulted from various physical courses, the strong freeze thaw action within regolith, significant organic matter accumulation, evident leaching and illuviation, as well as initial argillification dominated the formation and development of the soils on the Fildes Peninsula. Furthermore, this study indicated that the juvenility of genesis, poor profile expression, variation in column thickness, etc. characterized the pedogenetic features of the soils of the Fildes Peninsula.展开更多

"The Maritime Silk Road" needs desperately legal guarantee of State's marine rights and interest. The primary target of this paper is to put forward several suggestions on the legal guarantee of maritime rights protection based on analyzing the present situation of China legal system.展开更多
