The Huangtuling hypersthene-garnet-biotite gneiss at Luotian County, hubei Provine, is a typicalgranulite-facies rock of the Dabie Group Complex in the Dabie orogenic belt. Investigations on the morphology andoccurrence of zircons and their internal structures shown in the thin sections lead to the recognition of three types ofzircons, which are in good agreement with the types identified on the basis of morphology, colour and external fea-tures from the related zircon concentrates. The observation of zircons in the rock reveals that part of type 1 zirconsshow signs of a double-layered structure. The interval part existed in the protolith prior to the granulite-facies meta-morphism. Type 2, the prismatic zircons which mainly occur in garnet and hypersthene are metamorphic minerals ofthe granulite-facies metamorphism. Type 3, the round multifaceted zircons in felsic minerals and biotite, are proba-bly attributed to a later geological event related to migmatization. The ^(207)Pb/^(206)Pb zircon dating by direct evaporationon (thermal evaporation ion mass spectrometer) yields ages ranging from 2814 Ma to 1992 Ma. The age discrepancyamong these different zircon types is conspicuous. The yellow-brown(type 1) zircons give ages of 2814±29 Ma to2527±6 Ma, the prismatic euhedral zircons (type 2), 2456±7 Ma to 2254±4 Ma, and the round multifaceted zircons(type 3), 1992±10 Ma. The results are geologically interpreted in consideration of the complicated behaviours of zir-cons during Precambrian geological evolution of the Dabie area. (1) If the protolith of the gneiss is a sedimentaryrock, then type 1 zircons are clastic ones and the ages 2814±29 Ma and 2811±27 Ma may reflect the minimum age ofthe rocks of its source region. also the first geological event in the area. Sedimentation of the protolith occurred be-tween 2814 Ma and 2527 Ma, probably close to 2814 Ma. If the protolith is a volcanic rock, then the formation age ofthe supracrustal rocks of the Dabie Group Complex is

Objective To recognize and assess the impact of the South-to-north Water Transfer Project (SNWTP) on the ecological environment of Xiangfan, hubei province, situated in the water-out area, and develop sound scientific countermeasures. Methods A three-layer BP network was built to simulate topology and process of the eco-economy system of Xiangfan. Historical data of ecological environmental factors and socio-economic factors as inputs, and corresponding historical data of ecosystem service value (ESV) and GDP as target outputs, were presented to train and test the network. When predicted input data after 2001 were presented to trained network as generalization sets, ESVs and GDPs of 2002, 2003, 2004... till 2050 were simulated as output in succession. Results Up to 2050, the area would have suffered an accumulative total ESV loss of RMB 104.9 billion, which accounted for 37.36% of the present ESV. The coinstantaneous GDP would change asynchronously with ESV, it would go through an up-to-down process and finally lose RMB89.3 billion, which accounted for 18.71% of 2001. Conclusions The simulation indicates that ESV loss means damage to the capability of socio-economic sustainable development, and suggests that artificial neural networks (ANNs) provide a feasible and effective method and have an important potential in ESV modeling.

The issue concerning new generation migrant workers is an important part of current social management. How to improve employment ability of new generation migrant workers is the central part of improving living of migrant workers and development environment. Based on survey data of 6 counties in hubei province,I analyzed employment will and influence factors of new generation migrant workers. Researches have indicated that going out to work,employment opportunity,nature of subordinate service industry,industrial technical level,and financial support play a significant role in employment intention of migrant workers,while their employment ability is influenced by their cultural quality,professional skills, working endurance,degree of policy cognition,and information channel,etc. In view of these five aspects,I put forward following countermeasures: raise educational level,improve skills,strengthen endurance,enhance attention to policies,and expand information channel,to improve employment ability of new generation migrant workers.

Implication of Reported Viral Hepatitis Incidence Rate Change in hubei province, China, between 2004-2010

第二届中国青年学者微生物遗传学学术研讨会

作者： Kai Cheng, Da Pei, Fengxia Deng, Wei Liu, Yijun Zhao hubei Key Laboratory of Urban Water Environmental Ecology, Central China Normal University, Wuhan 430079, China

We carried out annual studies of virioplankton dynamics in several Chinese freshwater lakes with different trophic environments. Water was sampled monthly from 7 sites from August 2004 to July 2005, and we measured the abundance of viruses and bacteria, concentration of nitrogen, phosphorus and chlorophyll a, water transparency, and pH. Our results indicate that viral abundance is more closely related to host density than to the trophic status of the sampling sites. This in turn indicates that viral abundance is directly dependant on bacterial abundance in eutrophic lakes, while trophic status and temperature may only indirectly affect viral abundance. We also found that the slope coefficient of the regression between bacterial and viral abundance is higher in more productive water-bodies, and that the virus-bacteria ratio is significantly lower in less productive water-bodies, indicating that the control of virioplankton on its hosts may change according to the host density;this would help to explain the hypothesis of "Killing the winner".

This study examined the change of reported incidence rate for viral hepatitis in hubei province, China, between 2004 to 2010 to provide scientific evidence for viral hepatitis control. Reported viral hepatitis infection cases were queried from Centre for Disease Control of hubei province, China. The incidence of viral hepatitis A decreased steadily across the study period. Viral hepatitis B composed 85% of the viral hepatitis cases. When reported incidence rates for chronic hepatitis B increased, the rates of acute and unclassified cases dropped from 2005 to 2010. The reported viral hepatitis B incidence rate for males was around 1.5-2 times higher than for females. The average annual percentage change of reported viral hepatitis B incidence rates was 4%. The same index for viral hepatitis C was 28%. The reported viral hepatitis B incidence rate of people under 20 years old declined over the period. This decrease was mainly attributed to the recent implementation of vaccination plan. Reported incidence rate of viral hepatitis E also rose in those years. Having a better understanding on reported incidence rates of the present surveillance system is important for developing strategies for further prevention of viral hepatitis. In addition, the data showed that a surveillance system that differentiates new and former infected cases will be more effective in providing evidence for disease control.
