They show certain temporal-spatial distribution characteristics. Volcanic fragments were probably derived from two different volcanic sources north and south of the North China Platform, while the magma of the two volcanic sources was probably derived from the lower crust. A new stratigraphic correlation scheme is put forward for the Benxi and Taiyuan Formations in this region on the basis of previous biostratigraphic work with the regionally widespread volcanic event layers as the marker bed for the isochronous stratigraphic correlation on a super-regional scale and in conjunction with the maximum transgressive event layers.展开更多

By using MATLAB language to establish a SOM neural network model, this paper evaluates the coastal ecotourism suitability of four regions, Qingdao, Yantai, Weihai and Rizhao of Shandong Province and divides 33 subordinate regions of those four cities into four categories, i.e. regions poorly suitable for ecotourism resources, regions highly suitable for coastal ecotourism, regions secondly suitable for coastal ecotourism, regions ordinarily suitable for coastal ecotourism. Related suggestions on development of regional coastal ecotourism have been given in the final conclusions.展开更多
