Leisure tourism in Yichang City has entered a golden period of great development,great transformation,great improvement and great leap forward. However,while pursuing the development of tourism industry,it is required to pay attention to the problem of improving its industrial development. This article mainly studied the current situation and existing problems of tourism in Yichang. Finally,it came up with some solutions and suggestions about how to promote the development of leisure tourism in Yichang City.展开更多

Three species that can be assigned to this genus, which are Y. ancarpa sp. nov., Y. monocarpa sp. nov., and Y. biscarpa sp. nov. Yanjiahella is comparable to certain echinoderm taxa in terms of morphology and some biological structures, which might indicate the early evolution and diversification of ancestral echinoderm lineages from the early Early Cambrian Yangtze Platform. The discovery of putative echinoderms in the Yanjiahe Biota provides significant clues about the origination and evolution of the deuterostome phylum Echinodermata.展开更多

Practice shows that any large State planned project will bring prosperity to the local economy. The Gezhouba Dam Project in Yichang has provided the first opportunity for the city’s development During the first stage of the Gezhouba project from 1971 to 1980, the annual average progressive growth rate of fixed assets investment and展开更多

Therefore,in the construction process of ecological civilization in Hubei Province,how to get the optimal economic output with minimum resource consumption and minor environment damage is one of the most urgent problems. Based on the panel data of 12 prefecture-level cities in Hubei Province from 2005 to 2014,the Malmquist Productivity Index( MPI) was used to calculate the eco-efficiency of 12 prefecture-level cities in Hubei Province. According to the analyzed results,it was found that there was a downward trend of ecological efficiency in Hubei Province during the study period. As for the overall environmental production situation of the whole province in this period,results showed that environmental production efficiency was improved while the level of environmental production technology has decreased greatly. This phenomenon maybe result from different speed,because the speed of technical efficiency improvement was less than the extent of technology decline,which finally led that the Hubei Province's environmental productivity declined.展开更多
