Research of formation and submarine slope stability in Caofeidian Channel in Bohai Bay
Abstract: In this paper, by studying bathymetric survey and shallow seismic detection data over multiple periods of history, we outline the geomorphic features of Caofeidian Channel. The results of our studies indicate that the overall depth contour in the Caofeidian Channel sea area maintains its original form. The channel at the front end is dominated by erosion. The annual maximum erosion rate is -19 cm/a, and the maximum water depth reaches 42.2 m, which sets the highest record for the water depth in Bohai Bay; we preliminarily conclude that the formation of the early channel occurred because the subsidence rate of the deep structure is slightly smaller than the deposition rate of the upper strata, and Caofeidian Channel has existed for a long time, over 20,000 years. The trending of the channel experienced a transition from the NS to the NE and then NW direction; we conclude that endogenic and exogenic processes, such as geological structure, the evolution of the ancient Luanhe River Delta, marine hydrodynamics, and human activity, jointly control the development and evolution of the geographic system in the Caofeidian sea area. the slope stabilities under the extreme conditions of a heavy storm and an earthquake are analyzed by performing simulations.

Spatial Differentiation of Housing Dominance in Guangzhou and its Social Stratification Response
Abstract: Taking communities as a units, to build a comprehensive evaluation system of housing dominance in Guangzhou from the two aspects of building conditions and housing location conditions based on the theory of housing dominance. The building condition dominance is evaluated from four aspects: housing years, building structure, building area per household, and housing facilities; housing location dominance is evaluated by four aspects: housing dominance composed of convenience of daily life, convenience of public service, surrounding landscape level, and the quality of surrounding environment. Through the method of “quadruple evaluation model” and “average value” of dominance, the scores of community housing dominance are calculated, and the spatial differentiation pattern of housing dominance in Guangzhou is obtained. On this basis, I analyze the response relation between housing dominance and social stratification distribution in Guangzhou. Studies have shown that the social stratification distribution is determined by housing dominance, and the spatial differentiation pattern of housing dominance can largely reflect the pattern of social stratification differentiation. The characteristics of the housing dominance subsystems of different stratification are different.

The Application of 'Internet +' to Fossil Protection
Abstract: 'Internet +' represents a new form of economic development,which can optimize factors of production by internet and make an advanced conjunction between information technology and social economy. It can also remarkably promote creativity and prolificacy. With the development of fossil protection work, 'Internet +' can be also applied in the digital fossil technique, for example, makes it possible for modern information technology to serve paleontological research, popular science and fossil protection.
This paper discusses the technological and administrative problems of application of 'Internet +' in fossil protection, suggests constructing a digital platform which collects information of important fossil sites and specimens, and predicts the prospect of further developments in research, popular science and fossil protection.
