They are all distributed in the Upper Yangtze old land. As a result of the Hunan-Guizhou palaeo-faulting, the crust on the northern side of the fault was uplifted and became land, thus suffering denudation. The bauxitic substances left in the weathered crust evolved and were reworked into bauxite. On the other hand, the crust on the southern side of the fault sank and remained to be part of an ocean. The bauxite deposits of Ia and Ib subtypes were formed by in-situ enrichment of residual bauxitic substances in the weathered crust of the old land, but bauxite deposits of Ic and Id subtypes resulted from transportation, accumulation and sedimentation of allothogenous bauxitic substances on the weathered crust of the old land. The processes of transportation may be distinguished as dry transportation and wet transportation, both of which proceeded under atmospheric conditions.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

文摘In recent years,the scale of rice and shrimp cultivation in Hubei Province is expanding year by year,and cultivation model is innovating continuously,while consumption market is enlarging constantly.It realizes"dual use of one land,win-win of grain and fishery,stable grain production,and efficiency increase",and effectively solves the problems that"benefit of grain planting is low,and it is difficult to increase farmers'income".But there are still many problems at present,such as degeneration of crayfish germplasm,increase of disease incidence,centralized entering in the market affecting breeding efficiency,the benefits of rice not brought into full play,large number of business entities,lack of leading enterprises and sufficient supporting.To realize sustainable development of rice and shrimp cultivation industry,Hubei Province should adhere to the problem orientation,do a good job in supporting and capital guidance,increase effective supply,promote scale operation,cultivate leading enterprises,strengthen production management,and improve product quality.
文摘This paper discusses geological-geophysical-geochemical models of such typical deposits as the Tieshan-type Fe-Cu deposit, the Tonglushan-type Cu-Fe deposit, the Yehuaxiang-type Cu deposit, the Jiguanzui-type Cu-Au deposit, and the Tongshankou-type Cu (Mo) deposit. The models were established based on practical data of the polymetallic deposits dominated by copper ore in southeastern Hubei. These models, which are graphically illustrated in the paper, systematically summarize the metallogenic geological conditions and the geophysical-geochemical characteristics of copper deposits in this area. The models are of practical significance for studying copper deposits, predicting mineral resources, choosing exploration methods, and searching for ore deposits based on existing ones in the study area.
文摘In the Cambrian-Ordoviclan strata in the lower reaches of the Qingjiang River (western Hubei province), many well-consolidated paleokarst breccia bodies of different sizes and occurrences have been observed. By studying them in detail and by introducing new ideas of modern sedimentology into the study, the authors described and classified these paleokarst breccias. Their forming conditions and mechanisms are also explained on the basis of our research
文摘By using multi-source and multi-temporal high resolution remote sensing data and related techniques of remote sensing and geographic information systems, this paper analyzes the spatial and temporal changes of land occupation caused by mine development in four mining areas of eastern Hubei Province from 2011 to 2014, including Chengchao-Tieshan iron-copper polymetallic deposit area, Daye-Yangxin iron-copper polymetallic deposit area, E-Nan mining area, and Wuxue-Yangxin non-metallic mining area along the Yangtze River. The results show that: In the research area, land occupation of energy mine exploitation is small and in scattered distribution, with coal mine occupying the largest area, showing a downward trend in four years; land occupation of metal mines is large and in centralized distribution, with iron mine and copper mine occupying the largest area, showing a downward trend in four years; non-metallic mines are large and in great quantity, with mines of limestone for building and limestone occupying the largest area, showing a upward trend in four years.
文摘Commercial linear alkylbenzene sulfonate (LAS), mixture of alkylchain lengths and phenyl position isomers (C10-C13), is widely used as a major constituent of household and industrial detergents in the People’s Republic of China. Degradation process and behaviour of LAS compounds during an 82-hour lake water die-away study, with an added LAS concentration of 1. 5mg .L-1, was quantified and accomplished by HPLO-UV after extractionon the SepPek C18 reversed - phase cartridges. The degradation rate became progressively faster with increasing chain length. The technique described in this study is fast, sensitive and specific, and can be used to determine low levels, of LAS and for establishing water quality criteria and standards relating to LAS and its compounds.
文摘Nowadays,Hubei Province pays more attention to sustainable development with the purpose of building green province. 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.
